19. Remove the retaining ring (1) from the 1-2-3-4 clutch piston housing (3).





20. Position the 1-2-3-4, 4-5 clutch housing (7) on the base of J 24204-2 (8) so that the rear of the housing is facing up.
21. Install J 43777 (5) onto the 1-2-3-4 clutch piston return spring assembly.
22. Align the J 43777 (5) notch with the gap in the retaining ring (6).
23. Install the J 43777 (4) extension onto the shaft of J 24204-2 (8).
24. Install the J 24204-2 ball bearing (3) and washer (2) onto the shaft of J 24204-2.
25. Install the J 24204-2 wing nut (1) onto the shaft of J 24204-2 (8).
26. Compress the return spring assembly until the retaining ring (6) can be removed.
27. Remove the retaining ring (6) from the groove in the 1-2-3-4, 4-5 clutch housing inner hub.
28. Remove J 24204-2 and J 43776 from the 1-2-3-4, 4-5 clutch housing.
29. Remove the retaining ring (6) from the 1-2-3-4, 4-5 clutch housing (7).





30. Remove the 1-2-3-4 clutch piston return spring assembly (1) from the 1-2-3-4 clutch piston (3).
