101. C5 Clutch Reaction Plate Selection

C5 Clutch Reaction Plate Selection

Tools Required
^ J24204-2 Bar and Stud Assembly
^ J44530 C3/C4 Piston Spring Compressor





Important: The C5 clutch backplate installs in either direction. The plate may have no grooves, one side grooved, or both sides grooved.

1. Install C5 clutch backplate (3).

Important: The C5 clutch pack uses a single selective reaction plate. The C5 clutch pack is stacked out of order to allow determining the required selective reaction plate part number. When properly stacked, the top plate is a reaction plate and the next two plates are friction plates. The selective reaction plate is not stacked. Reaction plates have an ID number stamped on a tang. The identification number that does not match the other identification numbers is the selective reaction plate.

2. Starting with a C5 clutch friction plate, alternately install the remaining five C5 clutch friction plates (2) and the C5 clutch reaction plates (1).





Notice: DO NOT install special tools, J tools, onto the gear thrust plate rivets of the C3 clutch backplate assembly. The special tools could damage the gear thrust plate rivets.

3. Install J24204-2 (3) and J44530 (1) into the main housing.
4. Make sure J24204-2 does not damage gear thrust plate rivets (4) on the C3 clutch backplate assembly.

Important: The C5 clutch plates need to be compressed enough to remove the coning from the plates. Hand tightening the wing nut of J24204-2 should be sufficient to remove the coning.

5. Using the J24204-2 wing nut, compress C5 clutch plates (2) until hand tight.





6. Place a 25 mm (1 inch) gage bar (2) on the rear surface of the main housing at a location near J44530.
7. Measure the distance from the top of the gage bar to the top of C5 clutch stack (3) (Dimension A).
8. Subtract dimension B. the width of the gage bar; from dimension A.
9. Dimension C is the result of the subtraction.
10. Select a C5 clutch reaction plate based upon Dimension C. Refer to Selective Components Specifications.





Notice: DO NOT damage the P1 planetary carrier bushing when removing J24204-2 from the main housing. The threaded rod of J24204-2 must pass through but not touch the bushing.

11. Remove J24204-2 (3), and J44530 (1).





12. Remove six C5 clutch friction plates (2) and five C5 clutch reaction plates (1).
