^ Tools Required
- J 6116-01 Rear Gear Holding Fixture
- J 36850 Assembly Lubricant





1. Assemble the main shaft (662) into the rear internal gear (666).
2. Install the main shaft retaining ring (670) onto the main shaft (662).





3. Assemble the spacer (691) onto the main shaft (662).
4. Assemble the sun gear rear thrust bearing (664) and races (663 and 665) onto the main shaft (662).
5. The lips on the sun gear thrust bearing races (663 and 665) should face the sun gear rear thrust bearing (664).
6. Retain the spacer, sun gear rear thrust bearing and races with J 36850 or equivalent.





7. Lubricate the output carrier pinion gears (655) with DEXRON III transmission fluid.
8. Assemble the main shaft and rear internal gear assembly (666) into the output carrier assembly (661).
9. Place the assembly into the J 6116-01 with the main shaft facing down.





10. Assemble the sun gear front thrust bearing (647) and races (648 and 669). The lips of the sun gear thrust bearing races (648 and 669) should face the sun gear front thrust bearing (647).
11. Place the bearing and race assembly onto the rear internal gear hub. Retain with J 36850 or equivalent.





12. Assemble the output shaft (671) into the output carrier assembly.
13. Install the output shaft retainer ring (672).
14. Assemble the output shaft thrust washer (673) to the output shaft. Align the output shaft thrust washer tabs with the pockets in the output carrier.
15. Retain the thrust washer with J 36850 or equivalent.





16. Turn the gear unit assembly over and place it into the J 6116-01 with the output shaft (671) facing down.
17. Install the output carrier thrust washer (659) into the output carrier assembly (661).
18. Lubricate the reaction carrier pinion gears with DEXRON III transmission fluid.
19. Assemble the reaction carrier assembly (651) into the output carrier assembly (661).
20. Rotate the reaction carrier assembly (651) to ease assembly.





21. Assemble the sun gear (650) into the reaction carrier assembly (651).
^ Insert the chamfered inner diameter first
^ Rotate the sun gear to ease assembly
22. Assemble the sun gear shaft (649) with the long splined end into the sun gear (651).





23. Assemble the longer lipped sun gear rear thrust bearing race (648) onto the sun gear with the lip facing upward.
24. Assemble the sun gear front thrust bearing (647) onto the sun gear rear thrust bearing race (648).





25. Assemble the sun gear front thrust bearing race (646) to the rear hub of the center support (640). Retain the sun gear front thrust bearing race (646) with J 36850 or equivalent.
26. Assemble the reaction carrier thrust washer (642) (brass) into the recess of the center support. Retain the reaction carrier thrust washer (642) with J 36850 or equivalent.





27. Install a new center support (640), or the reconditioned center support, into the reaction carrier (651).
28. Verify correct assembly by holding the reaction carrier assembly (651) stationary and by rotating the center support (640). The center support (640) should only turn counterclockwise.
