10. Install and load low/reverse spring compressor tool (3, 4, 5) as shown to facilitate snap ring (2) installation.




11. Install snap ring (1) and remove compressor tool.




12. Install rear carrier (4) front bearing cone.





Check output bearing preload. Output bearing preload must be checked and/or adjusted if any of the following items have been replaced:

- Output shaft (rear carrier assembly)
- Output shaft bearings
- Transmission case

13. PRELOAD CHECK/SHIM SELECTION: Install rear output shaft bearing cone and Support Plate 6618A (1).




14. Install Support Plate 6618A (1). Lightly tighten retaining screws. Screws should be below the plate surface, but do not snug screws.
15. Turn case over on arbor press so that the plate is resting on the press base.

CAUTION: The output shaft will extend through the hole of Support Plate 6618A. Ensure your press table has clearance for the output shaft.




16. Install shim (1) on output shaft (2). Apply small amount of petrolatum onto the shim to hold it in place. Use the original shim as a starting point. If original shim is not available, use the thickest shim available.




17. Install output shaft/rear carrier into rear bearing. The shaft must be pressed into position. Use special tool MD-998911 (Disc) (2) and C- 4171 and C4171-2 (Handle) (1) to press shaft into rear bearing.





CAUTION: Do not re-use old output shaft nut because the removed stake weakens the nut flange. Using special tools 6497 and 6498-A, install new output shaft nut. Tighten new output shaft nut to 200 Nm (147 ft. lbs.).

18. Check the turning torque (1) of the output shaft. The shaft should have 1 to 8 in. lbs. of turning torque. If the turning torque is higher than 8 in. lbs., install a thicker shim. If turning torque is less than 1 in. lb., install a thinner shim. Make sure there is no end play.





CAUTION: Failure to stake nut could allow the nut to back-off during use.

19. The new nut (3) must be staked after the correct turning torque is obtained. Use Staking Tool 6639 (2) to stake output shaft nut.




20. Verify that the nut has been properly staked (2) to the output shaft.
21. Install the snap ring onto the output shaft




22. Install low/reverse clutch pack (1, 2). Leave uppermost disc out to facilitate snap ring installation.

34. Set up Tool 5058 (1) as shown. Compress 2/4 clutch just enough to facilitate snap ring installation.




35. Measure 2/4 clutch clearance: Set up dial indicator (1) as shown. Press down clutch pack with finger and zero dial indicator. Record measurement in four (4) places and take average reading. The 2/4 clutch pack clearance is 0.76 to 2.64 mm (0.030 to 0.104 inch). If not within specifications, the clutch is not assembled properly or is excessively worn. There is no adjustment for the 2/4 clutch clearance.




36. Install the #7 needle bearing (1) to the rear sun gear (2). The number 7 needle bearing has three antireversal tabs and is common with the number 5 and number 2 position. The orientation should allow the bearing to seat flat against the rear sun gear. A small amount of petrolatum can be used to hold the bearing to the rear sun gear.




37. Install rear sun gear (2) and #7 needle bearing (1).




38. Install front carrier/rear annulus assembly (2) and #6 needle bearing (1).




39. Install front sun gear assembly (1) and #4 thrust washer (2).




40. Determine proper #4 thrust plate thickness. Select the thinnest available #4 thrust plate.
41. Install #4 thrust plate (2) using petrolatum to hold into position.
42. Install input clutch assembly. Ensure the input clutch assembly is completely seated by viewing position through input speed sensor hole. If the speed sensor tone wheel is not centered in the opening, the input clutches assembly is not seated properly.




43. Remove the oil pump O-ring (2) and install oil pump and gasket to transmission. Use screw-in dowels or phillips-head screwdrivers to align pump to case. Be sure to reinstall O-ring on oil pump after selecting the proper No. 4 thrust plate.




44. Measure the input shaft end play with the transmission in the vertical position. This will ensure that the measurement will be accurate.
45. Set up and measure endplay using End Play Set 8266 (1, 2) and Dial Indicator Set C3339 (3) as shown.
46. Measure input shaft end play. Input shaft end play must be 0.127 to 0.635 mm (0.005 to 0.025 inch). For example, if end play reading is 0.055 inch, select No. 4 Thrust Plate which is 0.071 to 0.074 thick. This should provide an input shaft end play reading of 0.020 inch, which is within specifications.




47. Remove oil pump, gasket, and input clutch assembly to gain access to and install proper #4 thrust plate.
48. Install input clutch assembly (1) with proper thrust plate.




49. Install #1 caged needle bearing (1).
