Recommended Sequence for adjusting pinionring gear sets

When it is necessary to adjust the pinion ring gear, ist is in the interests of efficiency to adhere to the following sequence of procedures 1. Determine total shim thickness Stot (S1 plus S2) for the specified preloading of tapered roller bearing differential. 2. Determine total shim thickness Stot (S3 plus S4) for specified preloading of tapered roller bearing drive pinion. 3. Divide total shim thickness Stot in S3 and S4 in such a way that the distance from the center of the ring gear to the...

Checking Dimension E

Install drive pinion with measured shims S3 and S4. Bolt end plate and rotate drive pinion in both directions about 20 full revolutions by hand, so that both tapered roller bearings will be preloaded by the rotation and can settle. 2. Apply universal gage and check distance. 3. If shims have been selected correctly, the dial gage read counterclockwise should display the value of deviation r inscribed on the ring gear to a tolerance of
