Differential Turning Torque Adjustment

ADJUSTMENT - DIFFERENTIAL TURNING TORQUE

NOTE: Differential turning torque should only be measured with the geartrain out of the transaxle. If measurement is taken with transaxle assembled, an inaccurate measurement will result.

NOTE: All differential cover-to-case bolts and bearing plate-to-case bolts must be installed and torqued to obtain accurate measurement.

1. If transaxle is assembled, remove geartrain and leave differential in place.
2. Install differential cover and torque differential cover-to-case bolts to 54 Nm (40 ft. lbs.).
3. Install extension housing and torque extension housing-to-case bolts to 28 Nm (250 inch lbs.).
4. Place transaxle on work bench so axle centerline is parallel to the ground.
5. Install turning torque tool C-4995 to differential at side opposite extension housing.





6. Using inch lbs./Nm dial indicator, rotate differential case multiple times and record measurement (Fig. 91). Differential turning torque should be within 2.3 - 3.4 Nm (20 - 30 inch lbs.). Refer to shim chart for proper shim selection. If turning torque measured is less than 2.3 Nm (20 inch lbs.), install a thicker shim. If turning torque measured is greater than 3.4 Nm (30 inch lbs.), install a thinner shim.
