CVT Repair Project

 

On my 25th, 2012 my std. Burgman 650 lost all traction as I was trying to get onto a highway onramp.  

I thought I heard a slight thud and a small jerk coming from the engine and then the throttle went flat with no way to get into any gears,

it would just rev into the higher RPMs. No F1 warning or code on the display.

Shut the engine off hoping for one of those Burgman miracles wishing that somehow the ECU had gone a bit goofy. Alas the scoot was as dead as a duck stuck in ice on a cold Winter lake...

It was clear that I wasn't going anywhere, so I called a tow truck and had it towed to the house, thankfully I was just only 8 miles away.

Here is a pic of what a 600 lbs paper weight looks like on the back of a tow truck.

I knew this day would eventually arrive, but now that it is here, I am totally bummed about it.

The scoot fires up and the engine idles and revs nicely but there is no play once the throttle is opened, the rear wheel doesn't spin

and I hear a slight clacking sound coming from the CVT.

I am inclined to think that the belt has broken but that is just an educated guess right now.

I will have to tear it down, take the CVT out and see what has gone wrong.


Planning -- Preparation

I formulated a plan of attack and put together my project details.  In the end I decided to divide the project into three main parts:

1. Tupperware Removal / Installation

2. Engine Removal / Installation

3. CVT Removal / Inspection / Installation

In order to gain access to the CVT housing on the 650, you must first strip it off all its tupperware.  

It sounds like a daunting task but it is rather simple if you take your time, it is basically a 25 steps process.

Next you need to separate the Engine from the frame, which is a 38 steps process, most of which is spent disconnecting electrical connections.  The only difficult part of the project is removing the throttle body assembly.

You can turn your attention to the CVT assembly once you have the engine separated from the frame.  

You will have to separate the CVT assembly from the engine body and crank it open to inspect its internal parts.


1.

Tupperware Removal / Installation

Removing the body parts on the 650 is rather easy, provided you follow the OEMs recommended steps.  

The table below shows the order in which I removed all the tupperware.  

Each piece has its own corresponding DIY document which you can check for more detailed step by step instructions and an accompanying video.

The video below shows the the entire Burgman striptease from start to finish:

Use saran wrap / plastic wrap to protect the painted pieces.  I wrapped all my painted pieces in saran wrap while in storage / on the shelf.

 

 

Here are some pictures of the finished tupperware project:

You are done with Phase 1.

Step

Tupperware Reinstallation

The tupperware can be reinstalled in the reverse order of how it was taken off.

However, I found that a few things deviation from the previous removal steps could make the reinstall go a lot easier which I have outlined below along with any pertinent torque values.

24.

I cleaned the trunk inside and out and installed it back in place and hand tightened the 8 mm bolts.

23.

Install the seat rail and torque the bolts according to the torque values below.

There are two side M10 bolts and two top M8 bolts.

Torque value for M10 side bolt.:  36 lb-ft

Torque value for M8 side bolt..:  16.5  lb-ft

Apply Thread Lock 1360 to the M10 bolts.

21.

Install the sub-frame brace first, it will make it easier to install the muffler bracket.

22.

Install the muffler bracket after installing the sub-frame brace.

Torque value:  16.5 lb-ft

19.

 

18.

Attach the Left / Right Tail Lights to the Left / Right Frame Covers.

Route the cables for the Left / Right Tail Lights and connect them to the OEM harness.

Install the seat Strut before installing the right Frame Cover.

If you plan to tap into the license plate for a switched power supply system, this is the time to do it.

Tap into the wire and route your cable to the front before installing the left Frame Cover.

  

    

Install the Left / Right Frame Covers and connect the harness / bulbs to the Tail Lights.

16.

20.

Install the Trunk Box Cover before the Seat.

Install the Battery before installing the Seat, a lot easier without the seat in the way.

Install the Seat and connect the seat strut.

15.

Install the Pillion Handle Bars.

The torque value is the same for all the Pillion Handle Bars.

Torque value:  16.5 lb-ft

13.

If you plan to power the lights on your top-box, this is the time to tape into the tail light wires and install your top box power cable and route it befoe installing the Center Frame Cover.

Tap into the wires using the pictures below:

   

Route your top box power cable:

   

Install the Center Frame Cover.


2.

Engine Removal / Installation

Now that you have all the tupperware off the scoot, it is time to turn your attention to separating the engine from the frame.  This part of the project consists of 38 steps, most of which is disconnecting electrical connections.  

Step

Preliminary Steps

There a number of preliminary steps that need to be done before starting the actual work on separating the frame from the engine.  

Perform the following:

1.

Disconnect the battery and put aside.  Battery Replacement / Maintenance 

I put mine on a trickle charger for the duration of the project.

2.

Drain the Engine Oil.    Engine Oil Change

3.

Drain the Transmission Oil.   Transmission Oil Change

4.

Drain the Coolant.  Coolant Maintenance

Drain the overflow reservoir.

5.

Cover the CVT filter opening to keep foreign elements out

Cover the CVT Exhaust opening to keep foreign elements out

Engine Removal Steps

1.

Remove the Air-Cleaner Box.  It houses the air-filter.  

Disconnect the following:

  • Joint hose (1)
  • Breather hose (2)

 

2.

Remove the air cleaner box.  Air Cleaner Box

  • Remove the Fuse Block (undo the 4 Phillips screws)
  • Remove the top bolt (10 mm)
  • Remove the bottom bolt (10 mm)
  • Remove the Air-Cleaner Box.

   

 

Tip:

The service manual calls for the radiator to be removed later on.  

However, I found it to be more effective to remove the radiator first, thus gaining easier access to the air chamber and the throttle body assembly.

3.

Disconnect the following:   Radiator

  • Engine coolant breather hose (3)
  • Radiator hose (4)

 

4.

Disconnect the radiator inlet hose

5.

Disconnect the cooling fan switch coupler (5)

6.

Remove the radiator:

  • Remove the main radiator bolt
  • Remove the two swivel arm radiator bolts
  • Remove the radiator

     

 

7.

Remove the following:    IAP / IAT / PAIR Solenoid Couplers

  • IAP sensor lead wire couple (1)
  • IAT SENSOR (2)
  • PAIR solenoid valve lead wire coupler (3)
  • Disconnect the vacuum hose

  

8.

Disconnect the vacuum hose (4) from the IAP Sensor

9.

Loosen the throttle body clamp screws

10.

Remove the PAIR solenoid valve (5)

 

11.

Remove the air chamber (6)  Air Chamber

  • Remove the 10 mm bolt
  • Disconnect the hose at the front
  • Remove the side joint hose to make the removal easier
  • Remove the Air-Chamber

     

12.

Disconnect the throttle cables (7)  Throttle Cables

  • Loosen the top throttle cable
  • Loosen the bottom throttle cable
  • Remove the cable anchors from the throttle wheel

Tip: I had to loose the throttle wheels 11mm bolt to free the cable anchors.

Tip: Label your cables so you know which one is the top and bottom cable.

 

13.

Disconnect the injector couplers (8) Throttle Assembly

 

14.

Disconnect the following:

  • TP SENSOR COUPLER (9)
  • IAC valve coupler (10)

 

15.

Loosen the throttle body clamp screws

16.

Disconnect the fuel delivery hose

 

17.

Remove the throttle body assembly

  • Disconnect the throttle body hoses

Removing the throttle assembly can be a bit tricky.  It would not come loose freely on my std. burgman 650 with just pure raw hand power.  In the end I had to resort to a small pry bar to lever it out by putting some pressure on a solid surface at one end and using the frame as a support surface.  Once I was able to loosen one end, the other end just popped out by itself.

Tip: I had to use a small pry bar to remove the throttle body.  

Tip: Once the throttle body is removed, use two small plastic bags to cover the engine intake openings.

    

Tip: Place the throttle body inside a clean plastic bag and set it aside in a safe place.

Tip: Check the inside of the throttle body assembly and clean it if you see any build-up.

   

  18.

Disconnect the following:

  • Pair Hose (1)
  • Crankcase Breather Hose (2)

Those were done in a previous step.

19.

Disconnect the engine ground lead wire  Engine Ground Wire

  • You will need an 8mm socket with a long extension as there is no room to operate a socket inside the engine.

 

20.

Disconnect the following: Disconnect Couplers

  • Disconnect the center stand switch lead wire coupler (1)
  • CVT pulley position sensor lead wire coupler (2)
  • CVT motor lead wire coupler (3)
  • CVT secondary pulley revolution sensor lead wire Coupler (4)
  • HO2 sensor lead wire couple (5)

 

21.

Disconnect the starter motor lead wire Starter Motor Wire

  

22.

Disconnect the ECT sensor coupler (6)  ECT Sensor

 

23.

Disconnect the following:  Step 23 Couplers

  • Disconnect the side-stand switch lead wire coupler (7)
  • Oil pressure switch lead wire coupler (8)
  • Oil Level switch lead wire (9)

  • Trunk light seat switch lead coupler (11)

24.

Disconnect the CMP sensor coupler (12)  CMP Sensor / Spark PLug Couplers

 

25.

Disconnect  the Ignition coil/spark plug cap wires

 

26.

Disconnect the generator coupler (1)  Generator / HO2 sensor Couplers

  • After disconnecting the coupler, trace the wire and remove it and let it hang on the side as it is attached to the engine.

27.

Disconnect the HO2 sensor coupler (2)  Generator / HO2 sensor Couplers

  • After disconnectiong the HO2 coupler, trace it downward and remove its holding loop below

 

28.

Remove the muffler  Muffler

  • Remove the 6mm hex bolts connecting the muffler to the engine at the front
  • Remove the 12 mm muffler bolt in the middle to drop the muffler.

Tip:  Place someting under the muffler before removing the 12 mm middle bolt.  It is rather heavy and will fall to

       ground if not supported.

Tip:  Cover the engine exhause holes to keep foreign elements out once the muffler has been removed.

    

    

29.

Remove the brake-lock cable clamp  Remove Brake-lock clamp/hose clamp/caliper

 

30.

Remove the Rear brake hose clamp

 

31.

Remove the rear brake caliper bolts and remove the rear brake caliper (3)  

 Rear Wheel Removal--Install

  • Remove the Rear Brake Caliper and let it hang on the outside of the frame until you have removed the shock absorbers.  
  • Once the shock absorbers are removed, move the brake fluid hose to the top of the frame and let it hang there.  (I zip-tied mine in place for some added security).

Tip:  I always insert a plastic shim between the brake pads on the caliper to prevent the pads from collapsing if

       the rear brake is applied by accident.

32.

Remove both sides of the rear shock absorber lower bolts (4)   Remove Rear Shock Bolts

  • Remove the Left / Right 14 mm lower shock absorber bolts
  • Loosen the top bolts a bit so you can lift the absorber.  This way they will drag on the ground when you remove the frame.

      

Note: The rear swing arm will drop by 1-2 inches once the shock absorber bolts are removed.

Tip:

The service manual calls for removing fuel line clamps and the fuel feed hose.

I found it easier to simple remove the fuel hose line from the front of the engine and let it hang on the side of the frame.  Decide for yourself what works best for you (steps 33-34).

33.

Remove the clamps  Relocate Fuel Line

I left my my line in place and didn’t bother with removing the clamps.

Undo the clamps if you deem it necessary.  

34.

Move the fuel feed hose not to interfere with the work

  • I traced the fuel line and moved it to the outside of the frame and left it clamped in place.
  • I zip tied mine in place so it would not get loose.

 

Tip:

I opted to use a mover’s dolly with a 1000lbs capacity instead of just an engine jack so I could moved the engine around the garage.  Decide what works best for you. (step 35).

At first I supported the engine with a jack and then lowered it onto the dolly and removed the jack later.

35.

Support the Engine using an engine jack  Support Engine

  • Place a jack under th engine and lift it a bit so it is supported slightly.  Don’t over lift it as it can cause the rear center stand to lose its balance and tipe the engine/bike over.

This is how I did mine:

  • I place the jack under the engine.
  • I place the dolly over the jack
  • I placed a piece of wood over the dolly and lifted the engine about ¼ of an inch.
  • Once the frame was removed, I lowered the piece of wood supporting the engine onto the dolly.

  

Later on, I removed the center stand which allowed me to move the engine around the garage.

36.

Remove the engine mounting bolts and nuts.  Remove Engine Mounting Bolts/Nuts

Both the engine and nut are 14 mm.  I would recommend using a breaker bar as the bolts are on pretty tight.

You may hear some squealing as you loosen them.  All three on mine required the use of a breaker bar.

Once loose, you can use a ratchet to get them out.

The back bolt requires the use of an extension bar as it sits in a recessed area.

I had to remove the rear passenger bracket to give myself some additional operating room.

Note: The engine bolt nuts are not reusable, you will have to replace them as they lose their tigthtening

         characteristics after they have been torqued to spec.

I removed the bolts in the following order:

  1. Rear Bolt / Nut                  
  2. Bottom Bolt / Nut / Collar    
  3. Top Bolt / Nut                    

Note: The bottom bolt has a small collar that fits between the frame and the engine, be sure to capture it and

         store it safely, you will need it at assembly time.

To remove the bolts / nuts, you will have to hold the nut with a wrench / socket and loosen the bolt from the other side.

 

37.

Remove the foot board bracket  Remove Foot Board / Side Stand

  • Remove the 12 mm foot board bolts.  There are two of them.
  • Once removed the side stand assembly will come off.

  

Tip:

I used a mover’s dolly to support the rear end of the frame so I could move the frame around and park it out of the way.

38.

Remove the engine from the frame.  Remove Engine from Frame

To separate the frame from the engine, do the following:

  • Make certain that the following couplers are all handing loosely on the side of the engine:

 

  • Hang the Rear Caliper over the frame

  • Remove the Engine Coolant hose so it won’t interfere with the frame removal.

I reinstalled mine once I had removed the frame.

  • Separate frame from the engine by lifting it at the back, moving forward as you straddle the engine.  Be carefull not to lose your balance as the front end is hard to steer.
  • Carefully lay down the frame ahead of the engine.  I had mine rest on a mover’s dolly.

A few pics of what the engine and separate frame look like by themselves:

     

  

You are done with Phase 2.

Engine Installation

Reassembly for phase 2 is basically the reverse order of the disassembly.

I am including the torque values for those steps that require torquing the bolts to spec.

I would highly recommend that you buy a torque wrench and follow the recommended specs by the OEM.

Step

Engine Installation Steps

37.

Foot Board Bracket: M8 (19 lb-ft)

36.

The engine mounting bolts must be replace after being undone, make sure you replace them.

The torque value is the same for all three bolts, top, bottom and rear.

Engine Mounting Bolts / Nuts: (40.5 lb-ft)

32.

Torque the rear shock top and bottom bolts to spec.

The torque value is the same for the top and bottom.

Rear Shock Bolts: (21 lb-ft)

Tip: Make sure the brake fluid line is properly placed behid the bottom right spring.

31.

Brake Caliper Bolts. (19 lb-ft)

30.

Brake Hose Clamp. (19 lb-ft) The rear clamp behind the spring.

Hand tighten the small clamp bolts in front of the spring.

29.

Brake Lock Bolts: (19 lb-ft)

Hand tighten the small clamp bolts.

28.

Muffler bolts.  The torque value is the same for all of them.

Muffler Bolts: (16.5 lb-ft)

17.

Reinstalling the Throttle Assembly was the most challenging part for me.  

Once I devised a plan on how to hold the assembly in place, using a pry bar, I was able to seat it by using a rubber hammer from the reverse side.  

Having the radiator out provides ample room to use the rubber hammer.  

You will have to remove the IAC Hose and IAC Hose Connector to gain a solid surface on top of the assembly to hold it in place and push it in.  

    

I also used a small amount of vaseline at first to get the assembly partly seated and then sprayed a bit of silicon spray now and then as I continued to seat it.  

Read about my second try technique below, works  much better.

I had to remove the assembly once more for another reason.

This time around I tried a different approach, and the trick is the way you seat the assembly and the direction in which you try to seat it.  I tried to seat it from to back above, however if you reverse the direction and go from back to front, you will have a lot more leverage.

On the second try I only used a pry bar to seat the assembly.  I seated it with the body partly seated at the front and then used a small pry bar pushing it against the frame and pushing on the assembly’s edges on the left, center and right, took all of but 5 minutes to get it back in, much more effective than the hammer from behind technique.

16.

Reposition the fuel line and connect it to the throttle assembly.

Make sure that it is free of any defect and doesn’t come into contact with any sharp corners that could cut into it.

15.

Tighten the throttle assembly clamp screw according to the direction in the picture below:

 

11.

Install the air chamber onto the throttle assembly.

It’s a tight fit so be patient and it will fall into place

Tighten the Air Chambler clamp screws according to the picture below:

 

Install the side hose and tighten it.

It has a directional tab that needs to be positioned properly.

 

Don’t forget to add coolant, engine oil and transmission oil.

 


3.

CVT Removal / Inspection / Installation

Now that the engine is separated from the frame, you can begin the process of separating the CVT assembly from the engine and split it open to inspect its internal components.

Depending on the type of damage your CVT may have sustained, you may have to perform all or part of the follwing:

Special Tools

You will need a number of special tools as mandated by Suzuki in the service manual to remove the CVT assembly.

This DIY covers them in details:    CVT Special Tools 

Special Supplies

You will need some special parts in the form of lubes, thread lock, oils and others to reassemble the CVT.

Below is the OEM materials list from the service manual:

99000-25140 --> Suzuki Moly Paste

99000-25030 --> Suzuki Super Grease

99000-32050 --> Thread Lock 1342 (needed if replacing pulley parts)

99000-32130 --> Thread Lock Super 1360 (needed for pully bolt/nut torquing)

99000-31110 --> Suzuki Bond 1215

Engine Oil -----> To lube 2ndary pulley bearing (10w-40 or whatever you use in your engine)

Here is my parts list and what I used as equivalents:

Item

Description

Suzuki Moly Paste

I have been using Honda Moly Paste 60 for years.  

I had a tube on hand so I stuck with it.

Suzuki Super Grease

I used Mobile 1 Synthetic Grease which seems to be a good equivalent for the Suzuki Super Grease

Thread Lock Super 1360

I already had a bottle of Suzuki thread lock 1360 on had that I had purchased for a previous project.

Suzuki Bond 1215

I opted to use Permatex’s Ultra Grey RTV Silicone as it came highly recommended by seasoned DIYers on BUSA

Engine Oil

I used the same engine oil that I use on a regular basis in my 650.  Shell Rotella 15w-40.

Use whatever oil you normall use in your engine / transmission on the 650.

Dielectric Grease

I use Permatex’s dielectric grease whenever servicing electrical compoents, connectors etc...

Electrical Cleaner

I always clean my electrical connectors with some electrical cleaner prior to applying the dielectric grease

Anaerobic Sealer

You will need an anerobic sealer / gasket maker to seat the primary pulley bearing.  There are a number of products availble on the market.  I used Mopar’s Gasket Maker which is readily available at most Chrysler dealerships in the US.

I checked all the online OEM parts vendors and ended up buying from my favorite local Suzuki dealer in Van Nuys, California that pretty much beat all the online vendors and provided great service by double checking on everything and making sure that I got all the right parts for my specific model year.

The primary pulley has been redesigned for all model years and comes with a longer Primary Pulley Bolt and a deeper bolt housing insidne the primary pulley.

Turn around time for the parts order was about one week from the time I placed my order and had the dealer enter it into their ordering system with Suzuki.

Below are a few pics of the parts as they arrived from the warehouse.

CVT Assembly Removal

The CVT assembly removal starts with the Engine removal which was described in Phase 2 of this DIY.

Below is the CVT Assembly components picture from the Service Manual:

Step

Description

1.

Remove the bracket in front of the right center stand leg.

  • Remove the bottom 12 mm bolt
  • Remove the top 14 mm bolt (One of the CVT guides will bolt into this hole)
  • Remove the bracket

     Remove Bracket

2.

Remove the other two bolts.  The remaining two CVT guides will be bolted in these slots.

  • Remove the other 14 mm bolts

     Remove CVT Bolts

  3.

Install the special tool as shown  09920-31050 CVT Guide 

  • Install the CVT guides in place

    Install CVT Guides

Note:  The threads on my DIY guides didn’t thread easily into the engine casing so I used the engine

           mounting bolts instead.  The down side is that you have to unthread them before removing the

           CVT assembly.

4.

Remove the remaining CVT mounting bolts

  • Remove the 14 mm top bolt
  • Remove the 14 mm middle bolt
  • Remove the 14 mm bottom bolt

      Remove CVT Bolts

5.

Remove the CVT assembly

  • Use a small pry bar to start the CVT assembly separation
  • Insert the pry bar between the engine and the CVt casing and apply outward pressure
  • You should see a gap appear between the engine and the CVTassembly
  • Don’t use force, repeat the outward motion with the pry bar and the gap will continue to grow
  • Once the CVT assembly becomes loose, it will glide onto the CVT guides
  • Grab the CVT Assembly with both hands and slide it off the CVT guides

 Remove CVT Assembly

  

     

Note: I placed a block of wood under the CVT assembly so I could put it down once it came off the guides.

         I had to undo the replacement CVT guides first (as I had used the engin moutning bolts).

         I had forgotten to disconnect the center stand switch cable from the cvt assembly, do that first.

 

CVT Assembly Installation

Below are the service manual steps for installing the CVT assembly back onto the engine:

Step

Description

I performed the following preparation steps to get ready for the CVT Assembly installation:

  • Clean the engine side area around the Primary Pulley and Secondary Pulley Housings

  

1.

Remove the valve timing inspection cap (1)

  • Remove the valve timing inspection cap with a 10 mm hex socket / key and set it aside.

      Remove Valve Timing Cap

2.

Apply Moly Paste

I used Honda’s Moly paste instead of Suzuki’s.  I have been using it for years with great success.

   

  • Apply an even coat of Moly Paste to Secondary pulley splines on the engine side.

         

  

  • Apply an even coat of Moly Paste to the Primary Pulley splines on the engine side.

  

  • Moly Paste Fully Applied

 

  • Apply an even coat of Moly Paste to the Secondary Pulley Shaft adapter splines.

 

  • Apply an even coat of Moly Paste to the Primary Pulley Shaft adapter Splines.

 

  • Moly paste fully applied to both adapters

 

I added an additional personal step to the CVT Assembly installation.

You don’t have to perform this procedure if you see no value in it, it is not an Suzuki recommended step.

  • I applied a thin layer of Anarobic Sealant / Gasket maker to the outer rim of the Primary Pulley

          area on the CVT assembly which will press against the engine casing.  I am hoping this will help

          form a good seal to keep any water and other foreign material from migrating in to the primary

          pulley bearing area on the CVT Assembly.

     Apply Moly Paste

 99000-25140: Suzuki Moly Paste

3.

Install the special tool to the engine assembly as shown

I made a new set of CVT Guides from some old Engine Mount Bolts.

I cut off the bolt heads, rounded the heades and polished them.

 

  • Install the CVT Guides in their respective locations.

   Install CVT Guides

 09920-31050 CVT Guide 

I also removed the CVT cover on the left side of the engine in order to have a clear view of the splines on the engine side and to make sure that they lined up properly with those on the CVT Assembly.

  • Remove the 10 mm bolts holding the CVT cap in place
  • Once the cap is removed, you should have a clear view to the other side through the engine.

   

4.

Install the CVT Assembly onto the Engine

  • Carefully slide the CVT Assembly onto the CVT Guides

 

  • Push the CVT Assembly forward until it makes contact with the engine.

 6.

Remove the secondary pulley shaft nut by holding the shaft with the special tools

You will need a special tool to hold the shaft while undoing the nut.  I opted to use a DIY tool instead of the OEM Suzuki tool.

Check the   CVT Special Tools  for all the detailed information on the special tools.

 

You will also need an impact gun, be it electric or air operated.   This particular nut is torqued at 165 lb-ft, not sure how well an extension handle would work, plus you run the risk of stripping the nut.

You will also need a 34 mm socket to remove the pulley nut.

        09920-31020: Extension Handle

                09920-31030: CVT Secondary Pulley Shaft Holder

  • Carefully place the special tool shaft holder over the pulley adapter’s teeth and tighten it
  • Connect the 34 mm socket to your impact gun and place it over the shaft nut
  • While holding the special tool with one hand, undo the nut, it should come off with a few short bursts

  

     Remove Secondary Pulley Shaft Nut

7.

Remove the secondary shaft adaptor with a bearing puller

The service manual calls for bearing puller to remove the pulley adapter.  However, I found it to be rather unstable and prone to slippage.  

Another alternative is to use a platorm style puller / bearing separator which provides a much more stable platform to get the job done.

Check the   CVT Special Tools  for all the detailed information on the special tools.

  

You will also need an impact gun, be it electric or air operated.   This particular nut is torqued at 165 lb-ft, not sure how well an extension handle would work, plus you run the risk of stripping the nut.

  • Install the puller tool around the base of the pulley adapter
  • Complete the puller tool assembly
  • Place a socket or a spacer on top of the shaft collar
  • Place a piece of solid metal on top of the socket / spacer
  • Hand tighten the puller tool’s extraction lever / arm
  • While holding the puller tool at is base, apply torque to the extraction lever / arm to force the

         pulley adapter off the shaft

  • Clean and bag the adapter for safe keeping

  • A few short bursts of the impact gun should get the job done

 Remove Primary Pulley Bolt

 

    

    

9.

Screw in the special tool and remove the primary pulley shaft adapter

I used the smaller pulley puller from the kit I bought from Harbor Freight to remove the Primary Pullery Adapter.  It fit perfectly and made the job quick and easy.  

You will need to find a small tool to sit inside the shaft opening without damaging the inner threads.

As luck would have it I had a piece from another kit that fit perfectly, it’s called a Button.

Check the   CVT Special Tools  for all the detailed information on the special tools.

  

You will also need an impact gun, be it electric or air operated.   It will make quick work of removing the adapter.  

         09920-31040: CVT Primary PUlley Shaft Adaptor Remover

  

  • Install the pulley puller tool around the Primary Pulley Adapter

  • Clean the Secondary Pulley bearing housing with rubbing alcohol.

 

  • Apply Anti-Seize to the inside of the secondary pulley bearing housing.
  • Using a small brush, apply a thik coating of the anti-seize to the inside of the secondary pulley bearing housing.

   

Note:  I applied the anti-seize before installing the CVT Belt.  This way you don’t run the risk of

          accidentally getting any on the Belt.

  • Completely clean the Secondary Pulley from grease or any foregin matters

   

  • Clean the Secondary Pulley washer

 

  • Grab the Secondary Pulley and carefully place it between the rag on the Primary Pulley and the CVT bet.  Squeeze the CVT belt to help it move inside the secondary pulley
  • With the belt properly positioned between the two pullies, gently seat the secondary pulley bearing inside the bearing housing.

   

 Install Secondary Pulley

2.

Remove the rags

  • Remove the protective rag(s)

 

  • Check to make sure that the secondary pulley is firmly seated.

  

Caution:  Degrease the secondary pulley faces completely

              Use caution not to cause scratches on the pulley surfaces, make sure they don’t come into

              contact with one another

3.

Check that the secondary pulley is located inward relative to the primary pulley

  • Make sure that the secondary pulley is properly seated, there should be a 2mm gap between the primary and secondary pulley surfaces.  In other words the secondary should seat below the primary pulley.

  Check Secondary Pulley Position 

4.

Check that the CVT belt is in parallel with the CVT cover mating face

  • Visually check the line-up between the CVT belt and the rim of the CVT cover.

  Check CVT Belt Alignment 

5.

Install the primary slide pulley idle gear (1) and (2)

 Align Idle Gears (1) and (2) 

  • Start by cleaning the idle gear housings for idle gears (1) and (2)

  

  • Install the (1) primary slide pulley idle gear (the short one)

 

  • Install the (2) primary slide pulley idle gear (the long one)

 

  • Make sure that the idle gears (1) and (2)are correctly inter-meshed at the top.

  • Make sure that the idle gear (2) is correctly inter-meshed with the primary pulley gear.

 

6.

Turn the idle gear until the primary pulley face just touch the CVT belt

  • Turn the idle gear (2) to the left until the pulley surface makes contact with the cvt belt.
  • You will know it when it happens as it gets rather hard to turn the idle gear any further.

  Turn Idle Gear (2) to Close Primary Pulley  

7.

Check the CVT belt movement for smooth rotation by turning both pulleys

  • Turn the belt by holdin both pullies and turning them to the left.
  • The Belt should flow smoothly and you should not feel any resistance or any kind of metal hitting metal.
  • I used the arrow guide as a marker and performed a full rotation of the CVT belt.

  Check the CVT Belt movement 

8.

Install the secondary pulley washer (3)

  • Clean and install the secondary pulley washer.

   Install Secondary Pulley Washer 

CVT Belt

Step

Removal

My CVT belt was obliterated and there wasn’t much left of it to be removed the traditional way using the service manual steps.

Below are a few pics of what I found when I cranked open the CVT assembly:

    

If your CVT belt is intact, perform the following after removing the secondary pulley assembly:

  • Make sure that you are wearing clean protective gloves whenever you handle the CVT belt.

1.

Remove the Secondary Pulley by following the removal instructions for the pulley.

 

2.

Place a piece of clean rag on the CVT cover mating face to prevent the CVT belt from scratches

 

3.

Remove the CVT belt

4.

Notice the direction mark on the CVT belt

Note: If you are only replacing the CVT belt, it is not necessary to remove the primary pulley.

Inspection

1.

Make sure that the drive belt is grease free

2.

Inspect the CVT belt for cracks or uneven wear

3.

If any damage is found, replace the CVT belt with a new one

Note: Do not spray a cleaning solvent directly on the CVT belt

Step

Installation

1.

Install the Primary Pulley Assembly first by following the assembly/installation instructions for it.

 

  • Make sure that the CVT Cover is completely clean and freee of all foreign elements.

2.

Install the primary slide pulley idle gear temporarily

 

  • I skipped the slide pulley idle gear step and just turned the pulley with my finger

3.

Turn the idle gear clockwise and open the primary pulley fully

  • I turned the pulley by using my figer and turning the pulley to the left.
  • It will come to a stop once the pulley is fully open.

    Fully open Primary Pulley 

4.

Place a piece of clean rag on the CVT casing mating face to prevent the cvt belt from scratches

  • Place a rag over the CVT cover to protect the CVT Belt
  • I also placed an additional rag on the opposite side just to be sure.

    Place Protective Rag 

 

5.

Install the CVT belt so that the direction mark on the CVT belt point in the normal turning direction

A few pictures of the new CVT Belt:  Install CVT Belt 

      

  • Pay special attention to the directional arrow on the CVT Belt, it should be pointing to the LEFT when holding the CVT belt.
  • Carefully place the CVT belt between the covered CVT Cover and Primary Pulley’s edge.
  • Gently push down on the Belt until it is inserted between the pulley surfaces.

   

Caution: Never touch the side walls of the CVT belt.

6.

Place a piece of clean rag on the primary pulley faces to prevent them from scratches

 Place Protective Rag Over Pulley 

  • Remove the rag that was placed between the CVT Cover and the Primary Pulley
  • Place a rag on the opposite side of the Primary Pulley to protect it from possibly getting scratched when the Secondary pulley is installed.

    

7.

Install the Secondary Pulley by following the installation instructions for it.

Primary Pulley Assembly

Depending on the type of damage your CVT has experienced, you may have to remove the primary pulley assembly for inspection / repair.

  

Note: If you are only replacing the CVT belt, it may not be necessary to remove the primary pulley assembly.

Note: I would recommend taking the Primary Pulley out and inspecting the CVT housing, shim and o-ring since

         you already have everything apart.

Step

Removal

1.

Remove the primary pulley stopper bolt (1)

  • Place the CVT case on a flat surface
  • Using a 14mm socket remove the Primary Pulley Stopper Bolt

   

   

Inspect the bolt for wear and replace it if necessary.

The bolt in the pictures above only had 4k miles on it.  However, I had previously replaced the bolt at 32k miles and was in a similar condition.

2.

Remove the primary pulley assembly

  • Holding the CVT case with one hand, wiggle out the Primary Pulley Assembly

Note:  My Primary Pulley was stuck in place and would not come out by just pulling on it.  
        I had to improvise and put together an extraction plan to get the pulley out of its housing.

At first I tried the same approach used to remove the Secondary pulley.

Alas I was only able lift the primary for a mere 1/8th  of an inch and got stuck after that.

You will need the following for this approach:

  • 12 mm x 1.25 x 100 mm bolt
  • Washers
  • 2 four inches side support bars
  • 2 x 4 x 12 inches cross bar with hole drilled in the middle
  • Heat Gun

Do the following:

  • Apply heat to the CVT housing from the outside at its base
  • Place the side bars on a solid surface on the sides of the CVT case
  • Place the cross bar over the support bars
  • Thread the bolt onto the primary pulley shaft
  • Using a wrench start to tighten the bolt thus lifting the primary pulley off its housing.

   

I next put together a slider hammer solution which did the trick for me, and allowed me to remove the

Primary pulley.

I didn’t have a 12mm x 1.25 adapter for my slide hammer, so I improvised combing parts from my pulley

puller kit and slide hammer kit and ended up with the following:

 

Note:  I would not recommend this same approach if you are not replacing the primary pulley.  

         My pulley needed replacing so I wasn’t worried about damaging the shaft on it.

Once the Primary pulley comes loose, just lift it up and remove it from the CVT case.

   

3.

Remove the shim (1) and O-ring (2)

  • Reach in and lift the shim out of the Primary Pulley housing
  • Using a small flat head screw driver, extract the O-Ring

    

Step

Inspection

1.

Check that the primary pulley faces are free from any greasy substance

  • Clean the primary pulley surfaces with either rubbing alcohol or disc brake pad cleaner

Caution: If the surface is found greasy, make sure to degrease it thoroughly

2.

Inspect the primary pulley faces for any abnormal conditions

After cleaning the primary pulley surfaces, turn your attention to the entire assembly and inspect it for unusual wear patterns.

My primary pulley had suffered what is commonly refered to as stepping wear at the base of the shaft and had a melted shaft o-ring as can be seen in the pics below:

  

Inspect the rest of the primary pulley:

    

   

Open and close the primary pulley making sure that it operates freely and correctly:

   

 Remove Primary Pulley   Primary Pulley in Action 

3.

If any damages are found, replace the primary pulley assembly with a new one.

The primary pulley bearing on my CVT failed which led to the dreaded step wear on the primary pulley shaft.  As a result I had to order a new primary pulley assembly.

Suzuki has redesigned the Primary Pulley Assembly.  They made a few small engineering changes and increased the lenght of the stopper bolt wth a deeper stopper bolt slot on the assembly.

The new part number for all model years as of this writing in 2012 is 21070-10810 .

Below are a few pictures of what the new and old primary pulley assemblies along with some measurements.  

I was very impressed with the packaging for the primary pulley as it was shipped from the Suzuki:

     

Here are few pictures of the newly redesigned primary pulley assembly:

     

A few pictures of the old primary pulley assembly:

 

A few pics with measurements showing the differences between the old and new primary pulley assembly.

The stopper bold slot has been deepened to accommodate the longer pulley stopper bolt:

New Primary PUlley Assembly:   

Old Primary Pulley Assembly:   

The face/flange areas next to the stopper bolts have been reveresed, with the longer face being at the bottom and the shorter one on top on the new assembly model as seen in the pics below:

Old Assembly:   New Assembly:

A few pictures of the worn out shaft vs a normal shaft:

Damaged Shaft:    Normal Shaft:  

A few more pictures of the old and new primary pulley with some measurements.

The reason why I could not get the primary pulley out was due to the splines on the shaft having worn out which resulted in a small lip at the base of the splines as seen in the pictures below.  The old bearing would not fit past the damaged portion of the splines above the shaft.

5.

Inspect the Primary Pulley Housing inside the CVT case.

  • Clean the inside of the primary pulley housing inside the CVT case
  • Inspect it for signs of uneven wear or stepping wear
  • Inspect the primary pulley bolt hole

    

Step

Assembly

Caution: Wear clean protective gloves

1.

Degrease the inside of the CVT cover and casing completely with a cleaning solvent by using a clean rag.

I performed the following:

  • I used an engine cleaner to completely clean and degrease the inside of both the case and cover.
  • I followed up with a soap and water rinse to remove any reside that the engine cleaner may have left behind.
  • I finished with a complete wipe down using 50% rubbing alcohol.

   

I also use 1200 wet/dry emery cloth to clean and polish the inside of primary pulley and secondary pulley housing and the rim on both the CVT Case / Cover.

  

2.

Install the O-ring (1) and shim (2)

  Install Primary Pulley O-Ring and Shim

Perform the following to install the O-ring and Shim:

  • Wipe clean the seating area for the O-Ring.

  

  • Apply a thin bead of Ultra Grey to 4 spots in the O-Ring seating area

  

  • Install the O-ring by placing it in its seating are and press it firmly into place making sure it makes good contact with the 4 ultra grey beads.

  

  • Place the shim over the O-Ring and push it place making sure it is seated properly.

  

Caution: If any of the primary pulley, CVT casing or CVT cover has been replaced, insall the shim whose

             thickness has been adjusted in the shim adjustment procedure

3.

Perform the following prior to installing the primary pulley back inside the CVT case.

You will need the following supplies (Rubbing Alcohol / Anti-Seize).:  

  • Clean the Primary Pulley Housing.

 

  • Apply a thin layer of Anti-Seize to the inside of the primary pulley housing.

  

 Apply Anti-Seize

4.

Clean the Pulley surfaces and turn the slide pulley gear to fully close the primary pulley

  • Clean the Primary Pulley Surfaces with rubbing alcohol

 

  • Fully close the Primary Pulley by turning the slide pulley gear

  

 Clean and Close Pulley

Caution: Degrease the primary pulley faces completely

5.

Align the cutaway (B) of the screw shaft with the portrustion (A)

 

The new pulley has a different pulley cover cut out, the coutout in the back is much smaller than the old style.  

Below are some picstures of both the old and new primary pullies, use the one that fits your particular Primary Pulley model.
