J 45053 Universal Clamp Press

1. Inspect the front differential transfer drive gear assembly rear bearing assembly, located in the transmission case cover assembly, before installing the front differential transfer drive gear assembly (14) to be sure that all roller bearings are in the correct position.

Important: When the front differential transfer drive gear assembly (14) is installed correctly, the front differential transfer drive gear assembly and the output gear will mesh evenly. If not, the front differential transfer drive gear assembly did not clear all 4-5 clutch plates in the 4-5 clutch assembly or is not seated into the front differential transfer drive gear assembly rear bearing assembly, located in the transmission case cover assembly.

2. Using J 45053 install the front differential transfer drive gear assembly (14) to the transmission case assembly.




Important: 

•	The front differential transfer drive gear thrust washer (264) is available as a select fit washer.

•	When installing the 1st design 1-2 reverse internal gear, the thrust washer (264) is not select fit and does not use a letter marking. No adjustment to the endplay is necessary.

•	When using the 2nd design 1-2 reverse internal gear, the thrust washer (264) is select fit. Adjustment to the endplay is necessary when installing the 2nd design gear.

•	Either design requires the installation of the thrust washer (264) without any letter markings. The thrust washer (264) without letter markings is the thinnest thrust washer.

3. Install the front differential transfer drive gear thrust bearing washer (264) without any letter markings onto the front differential transfer drive gear assembly (14).
4. Install the front differential transfer drive gear thrust bearing assembly (263) onto the front differential transfer drive gear thrust bearing washer (264).



5. When installing the 2nd design 1-2 reverse internal gear, place a straight edge on the top of the rollers on the thrust bearing to reach across to the case surface.
6. Using a feeler gage, measure between the straight edge and the case.

Specification
1.269-1.645 mm (0.050-0.065 in)

7. If the measurement is not within specifications, refer to Shim Size Specifications to select the correct thickness thrust washer.



8. If the measurement is not obtainable, using the thickest washer, the 1-2 reverse internal gear (594) will require removal and then a thicker shim (596) installed. Refer to 1-2-Reverse Carrier Gear Assembly Installation .
9. Refer to Shim Size Specifications to select the correct thickness of shim to obtain the correct measurement.



10. Install again the front differential drive gear (14), the thrust washer and the thrust bearing.



11. Measure the thrust bearing height again to make sure it is in the specifications. If not within the specifications, adjust the height by changing the thrust washer.
