6. Remove twelve stud nuts and washers (3) and carefully remove the clutch spider (8) with a hoist and 1/2"-13 NC forged eyebolts. Be sure not to damage the clutch studs (16). Weight of the clutch spider (8) is approximately 65 lb. (29 kg).
NOTE: Put marks on clutch plates and clutch assemblies for installation purposes. This will prevent the wear of components.
7. Use 7/16"-14 NC screws and 1/2"-13 NC forged eyebolts and make a separation of the reverse clutch drive ring (9) from the clutch cylinder assembly (12).
8. Remove reverse clutch drive plates (10) and driven plates (11) from clutch assembly. Inspect the clutch plates (10) and (11) and make a replacement if worn or damaged.

10. Remove the forward clutch drive ring (13) from the plate assembly.
11. Remove the forward clutch plates (14) and (15) in the same sequence as the reverse clutch plates (10) and (11).
12. Remove the plate assembly (17). Make sure the main shaft group has support.
13. Remove retainer rings (19) from the forward piston (20) with tool (B).
14. Lift cylinder assembly (12) off forward piston (20). Be careful not to damage pins (23).
NOTE: The cylinder assembly will then have to be turned over to remove the retainer rings (19) on the reverse piston (18).
Assemble Clutches
NOTE: Before assembly install plate assembly on tooling (B).
1. Lift cylinder assembly (1) and put it on the forward piston (3) without damage to pins (2).
2. Install springs (4), washers (5) and retainer rings (6) with tool (A).
3. Install the clutch plates (7) and (8) in sequence with a sintered bronze plate first.
4. Install forward clutch drive ring (9) on plate assembly (10).
5. Install cylinder (1) on forward clutch drive ring (9).
6. Install reverse clutch plates (11) and (12) in the same sequence as for the forward clutch.
