Model C200






For quiet and reliable final drive operation, the following five adjustments must be made correctly:
1. Side bearing preload.
2. Pinion gear height.
3. Pinion bearing preload.
4. Ring gear-to-pinion backlash.
5. Ring and pinion gear tooth contact pattern.

A selection of carrier side bearing preload shims is required for successful completion of this procedure.
1. Make sure all parts are clean. Make sure, also, the bearings are well lubricated with light oil or type DEXRON automatic transmission fluid.
2. Place the differential carrier, with side bearings and bearing races installed, into the final drive housing.





3. Put the side bearing spacer in place.

CAUTION: Side bearing spacer is placed on either the right or left depending upon final drive gear ratio. Be sure to replace it on the correct side.





4. Use Tool number KV38100600 (J25267) to place original carrier side bearing preload shims on the carrier end, opposite the ring gear.





5. Install the side bearing caps in their correct locations and torque the bearing cap retaining bolts to 88 - 98 Nm (65 - 72 ft. lbs.)
6. Turn the carrier several times to seat the bearings.





7. Measure the turning torque of the carrier at the ring gear retaining bolts with a spring gauge Tool No. J8129.
Specification: 34.3 - 39.2 N (7.7 - 8.8 lbs.) of pulling force at the ring gear bolt.





8. If the turning torque is not within the specifications, correct the torque as follows:
- If the turning torque is less than the specified range, install washers of greater thickness.
- If the turning torque is greater than the specification, install thinner washers.





Refer to the illustration for washer dimensions and part numbers.
9. Record the total amount of washer thickness required for the correct carrier side bearing preload.





10. Remove the carrier from the final drive housing. Save the selected preload washers for later use during the assembly of the final drive unit.
