Turning Torque of Spiral Bevel Pinion Shaft and Differential
Assembly Combined (New Type : Without Collar)
1. Reassemble the differential assembly with shim 1 (1) and shim 2
(3) same as before disassembling.
2. Check that there is a backlash. If there is no backlash, remove a
shim 2 (3) and add a shim 1 (1).
(Reference)
• If the thickness of shims is not known, refer to the following.
• Reassemble the differential assembly with no shim at bearing
support L (2) side and with an adequate number of shims at
bearing R (4) side. And proceed to the next step.
3. Measure the turning torque by turning the spiral bevel pinion
shaft, and then remove a shim from the bearing R (4) if the
turning torque exceeds the factory specifications, or add a shim
to there if the turning torque is less than the factory specifications.
4. And repeat the above procedure until the turning torque becomes
the factory specifications.
