Torque Converter: Testing and Inspection

Differential Shim Selection





1. Install the differential and transfer shaft bearing cups on the bearings.





2. Install the Differential/Transfer Gear Bearing Shim Gauge 307-591 (307-591/1 and 307-591/2) on the differential and transfer shaft bearing cups.





3. Install the Differential/Transfer Gear Bearing Shim Gauge 307-591/3 (studs) in the transaxle case to align the torque converter housing.





4. NOTE: Make sure that the silicone has been cleaned off the machined surface of the transaxle case and the torque converter housing before installing the Differential/Transfer Gear Bearing Shim Gauge 307-591/3 (4 spacers) or the preload measurement may be inaccurate.

Install the Differential/Transfer Gear Bearing Shim Gauge 307-591/3 (4 spacers) on the studs to space the torque converter housing from the transaxle case.






5. Place the torque converter housing on the Differential/Transfer Gear Bearing Shim Gauge 307-591/3 (4 spacers).





6. Install the Differential/Transfer Gear Bearing Shim Gauge 307-591/3 (remaining 4 spacers, bolts and washers).
- Tighten to 24 Nm (18 lb-ft).






7. Install the Differential/Transfer Gear Bearing Shim Gauge 307-591/3 (4 nuts and washers) on the studs.
- Tighten to 24 Nm (18 lb-ft).






8. Rotate the transfer shaft and the differential several times to seat the bearings.





9. Using a feeler gauge, measure and record the smallest and largest preload gap on the Differential/Transfer Gear Bearing Shim Gauge 307-591/1 placed on the differential assembly. Add the 2 measurements and divide by 2. This is the thickness of the differential bearing preload shim. For additional information, refer to Specifications for the differential bearing preload shim part number.





10. Using a feeler gauge, measure and record the smallest and largest preload gap on Differential/Transfer Gear Bearing Shim Gauge 307-591/2 placed on the transfer shaft assembly. Add the 2 measurements and divide by 2. This is the thickness of the transfer shaft bearing preload shim. For additional information, refer to Specifications for the transfer gear bearing preload shim part number.





11. Remove the torque converter housing and the Differential/Transfer Gear Bearing Shim Gauge 307-591/3 (4 nuts, bolts and spacers and 8 washers) from the transaxle case.





12. Remove the Differential/Transfer Gear Bearing Shim Gauge 307-591/3 (4 spacers) from the transaxle case.





13. Remove the Differential/Transfer Gear Bearing Shim Gauge 307-591/3 (4 studs) from the transaxle case.





14. Remove the Differential/Transfer Gear Bearing Shim Gauge 307-591/1 and 307-591/2 from the differential and transfer shaft assemblies.





15. Remove the differential and transfer shaft bearing cups.





16. Assemble the torque converter housing. For additional information, refer to Torque Converter Housing .
