Part 1

ASSEMBLY










Use petrolatum on all seals to ease assembly of components.

1. Using an arbor press (2), install input shaft (1) to input shaft hub (3).










2. Install input shaft snap ring (3).










3. Place OD/Reverse piston (1) return spring (2) and snap ring (3) into position.










4. Using an Arbor Press (1) and Disc 6057 (4), install OD/Reverse piston (5) return spring (6) and snap ring (3).










5. Install the OD/Reverse piston assembly (1) to the input clutch retainer (2).










6. Install the input hub/shaft assembly (1) to the OD/Reverse piston/clutch retainer assembly (2).










7. Install input hub tapered snap ring (2).










8. Install UD clutch piston (1).










9. Install UD piston return spring (1) and Installer 5067 (2).










Refer to the exploded view as necessary when performing the following steps.










10. Place the UD spring retainer (1) and snap ring (2) into position.










11. Using Compressor 5059-A (6) and an arbor press (1), Install the UD spring retainer and snap ring (3), Compress just enough to install snap ring.

CAUTION: Compress return spring just enough to install snap ring.











12. Install the UD clutch pack (1,2). Leave out upper disc, until snap ring is installed.










13. Install the UD clutch flat snap ring (1) using a screwdriver (2).










14. Install the last UD clutch disc (1).










15. Place the OD/UD clutch reaction plate (1) and snap ring into position. The OD/UD clutches reaction plate has a step on both sides. Install the OD/UD clutches reaction plate tapered step side up.










16. Install the snap ring (1) using a screwdriver (2).

NOTE: Snap ring ends must be located within one finger of the input clutch hub. Be sure that snap ring is fully seated, by pushing with screwdriver, into snap ring groove all the way around.











17. Seat tapered snap ring (1) to ensure proper installation.










18. Install input clutch assembly (1) to the Input Clutch Pressure Fixture Tool 8391 (2).










19. Set up dial indicator (1) on the UD clutch pack (2).










20. Using moderate pressure, press down and hold (near indicator) (1) the UD clutch pack (2) with screwdriver or suitable tool and zero dial indicator. When releasing pressure on clutch pack, indicator reading should advance 0.005-0.010.

CAUTION: Do not apply more than 30 psi (206 kPa) to the underdrive clutch pack.

21. Apply 30 psi (206 kPa) to the underdrive hose on Tool 8391 and measure UD clutch clearance. Measure and record UD clutch pack measurement in four places, 90° apart.
22. Take average of four measurements and compare with UD clutch pack clearance specification. Underdrive clutch pack clearance must be 0.94-1.50 mm (0.037-0.059 in.).

23.




If necessary, select the proper reaction plate to achieve specifications:










24. Install the OD clutch pack (1,2).










25. Install OD pressure plate waved snap ring (1) using a screwdriver (2).










26. Install the OD/Reverse pressure plate (1) with large step down (towards OD clutch pack) (2).










Refer to the exploded view as necessary when performing the following steps.










27. Install OD pressure plate flat snap ring (3) using Compressor 5059-A (2) and an Arbor Press (1).










28. Measure OD clutch pack clearance. Set up dial indicator (1) on top of the OD/Reverse pressure plate (2).
29. Zero dial indicator and apply 30 psi (206 kPa) air pressure to the overdrive clutch hose on Input Clutch Pressure Fixture 8391. Measure and record OD clutch pack measurement in four places, 90° apart.
30. Take average of four measurements and compare with OD clutch pack clearance specification. The overdrive (OD) clutch pack clearance is 1.07-3.25 mm (0.042-0.128 in.).

If not within specifications, the clutch is not assembled properly. There is no adjustment for the OD clutch clearance.
