Assembly, Input Clutch: Assembly: Assembly

WARNING: This page is about a different car, the 2013 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

When installing the OD / Reverse piston Belleville spring, orientate it such that it contacts a new surface on the piston.

    NOTE:

    Install all new seals and o-rings onto the input shaft and input hub. The o-rings on the input hub are color coded. Be sure to install the correct o-ring in the correct location.

  3. Check the transmission lubrication check valve (20) located in the input shaft using shop air. The valve should only allow air flow in one direction. If the valve allows no air flow, or air flow in both directions, the valve will need to be replaced.
  4. Lubricate all seals with Mopar® ATF +4, Automatic Transmission Fluid, prior to installation.
  5. Assemble the OD/reverse piston (15) onto the input clutch hub (1).
  6. Assemble the input clutch retainer (13) onto the input clutch hub (1).
  7. Install the input clutch retainer tapered snap-ring (5) with tapered side up onto the input clutch hub (1).

  10. Install the UD balance piston return spring pack into the input clutch retainer.
  11. Install Piston (special tool #8252, Installer) (1) into the input clutch retainer to guide the UD balance piston seal into position inside the underdrive piston.

    NOTE:

    The UD clutch discs can be identified by their cross-hatched groove pattern (two sets of parallel grooves at 90 degrees to each other). The UD separator plates can be identified by semi-circular cutouts on the edges of the teeth. The reverse clutch and UD clutch use common separator plates.

  12. Install the UD balance piston (3) into the input clutch retainer and the underdrive piston.
  13. Using Spring (special tool #8251, Compressor, Spring) (2), compress the UD return spring pack and secure the piston in place with the snap-ring.
  14. Install the underdrive clutch pack into the input clutch retainer.

  15. Install the UD reaction plate lower flat snap-ring (16). The correct snap-ring can be identified by the two tabbed ears.
  16. Install the UD reaction plate (15) into the input clutch retainer. The reaction plate is to be installed with the big step down.
  17. Install the UD reaction plate upper tapered snap-ring (14) with tapered side up.

  19. Mount a (special tool #C-3339A, Set, Dial Indicator) (1) on the input clutch hub. Push down on the UD clutch discs and zero the indicator against the underdrive clutch discs. Apply 20 psi of air pressure to the underdrive clutch and record the dial indicator reading. Measure and record UD clutch pack measurement in four (4) places, 90° apart. Take average of four measurements and compare with UD clutch pack clearance specification. The correct clutch clearance is 0.84-1.54 mm (0.033-0.061 in.). The reaction plate is not selective. If the clutch clearance is not within specification, replace the reaction plate along with all the friction and steel discs.

  20. Install the overdrive clutch pack (13) into the input clutch retainer. The overdrive steel separator plates can be identified by the lack of the half-moon cuts in the locating tabs. The OD clutch discs can be identified by their radial groove pattern. The OD clutch discs can be identified by their radial groove pattern.
  21. Install the overdrive clutch wavy snap-ring (3) with the two tabbed ears into the OD/reverse piston.
  22. Install the OD/reverse pressure plate (4) into the input clutch retainer. The pressure plate is non-directional.
  23. Install the OD/reverse reaction plate flat snap-ring (6) into the OD/reverse piston.

  24. Mount a (special tool #C-3339A, Set, Dial Indicator) (1) on the input clutch hub and zero the indicator against the OD/reverse pressure plate (2). Apply 20 psi of air pressure to the overdrive clutch and record the dial indicator reading. Measure and record OD clutch pack measurement in four (4) places, 90° apart. Take average of four measurements and compare with OD clutch pack clearance specification. Verify that the clutch clearance is 1.103-1.856 mm (0.043-0.073 in.). The pressure plate is not selective. If the clutch clearance is not within specification, replace the pressure plate along with all the friction and steel discs.
  25. Install the reverse clutch pack into the input clutch retainer.
  26. Install the reverse reaction plate into the input clutch retainer.
  27. Install the reverse reaction plate selective snap-ring into the input clutch retainer.

  28. Mount a dial indicator to the assembly, push down on the clutch discs, pull up on the reaction plate to ensure the plate is properly seated and zero the indicator against the reverse clutch discs (2). Apply 20 psi of air pressure to the reverse clutch and record the dial indicator reading. Measure and record Reverse clutch pack measurement in four (4) places, 90° apart. Take average of four measurements and compare with Reverse clutch pack clearance specification. The correct clutch clearance is 0.81-1.24 mm (0.032-0.049 in.). Adjust as necessary. Install the chosen snap-ring and re-measure to verify selection.
    NOTE:

    The 65RFE uses one of three (3) different selective snap rings. They are identified by the end cuts (either straight [square] cut or "butterfly" [S-curved] cut):

    SELECTABLE END PLAY SNAP RINGS

    • One Square End, One Butterfly End = 1.55 mm (0.061 in.)
    • Both Ends Square Cut = 1.85 mm (0.073 in)
    • Both Ends Butterfly Cut = 2.2 mm (0.087 in.)
