Torque Converter Rebuild Form

What's a torque converter rebuild?

Goerend torque converters are eligible to be sent back to Goerend for rebuild. The purpose of a rebuild is to refresh, restall, or repair the converter. All rebuilds are videotaped when cut for quality assurance. A standard torque converter rebuild procedure is as follows:
  1. Converter and its internal components are inspected and cleaned.
  2. Impeller, turbine, stator, clutch plates, damper, and front cover are individually balanced.
  3. Multiple internal and external dimensional inspections are completed before assembly.
  4. Converter is welded together by TCRS alignment equipment with <0.003 runout tolerances.
  5. Converter is leak-tested under water, while under pressure.
  6. Converter is balanced as a unit and the runout tolerance is inspected again.
  7. Total height of the converter is inspected.
  8. Internal end-play is inspected.
  9. Lock up clutch is applied and inspected for leaks and holding power.
  10. Lock up clutch is released; lock up clutch and turbine are spun while impeller is stationary.
  11. Lock up clutch is examined to insure proper release and no internal component interference. 
  12. Impeller hub is lubricated and a protector cap is placed.
  13. New bolts are provided where necessary.
