DIFFERENTIAL BEARING PRELOAD ADJUSTMENT / SHIM SELECTION



Measure and adjust differential side bearing preload during any transaxle service, especially when the following components are replaced:

  • Transaxle gear case
  • Clutch bellhousing case
  • Differential case
  • Differential bearings

NOTE: True bearing turning torque readings can be obtained only with the geartrain removed from the case.






NOTE: Indicator is set up as shown for illustrative purposes only . Indicator must be parallel to T-Handle to obtain the most accurate reading.





total of end play, plus (constant) preload of 0.18 mm (0.007 in.).
STEP 7

The turning torque should be 6 to 12 in. lbs. If the turning torque is too high, install a 0.05 mm (0.002 inch) thinner shim. If the turning torque is too low, install a 0.05mm (0.002 inch) thicker shim.
