4-2. CLUTCH MAINTENANCE (Contd)
1. Loosen twelve screws (4) evenly until spring pressure is released.
2. Remove twelve screws (4), lockwashers (3), pressure plate (2), cover (5), and clutch disc (7) from
engine flywheel (1). Discard lockwashers (3).
3. Remove pilot bearing (8) from flywheel bore (9).
b. Cleaning and Inspection
1. For general cleaning instructions, refer to para. 2-8.
2. For general inspection instructions, refer to para. 2-9.
3. Inspect clutch contact face of flywheel (1) for grooves, scuff marks, and discoloration due to over-
heating. Replace flywheel (1) if damaged (para. 3-21).
4. Inspect clutch disc (7) for warpage of more than 0.004 in. (0.010 cm). Replace if defective.
5. Inspect pilot bearing (8) (TM 9-214). Replace if damaged.
6. Inspect flywheel bore (9) for dirt and metal particles. Remove dirt or metal particles.
c. Clutch Lever Adjustment
1.
Lay pressure plate (2) on flat surface and measure distance from outer surface of pressure plate (2)
to inner surface (14) of cover (5). Distance should be 1.281 in. (3.25 cm). If distance is not correct,
loosen and adjust three screws (13) until distance is correct at all points.
2. Measure distance from top of three levers (12) to inner surface (10) of pressure plate (2). If
measurement is not 2.16 in. (5.49 cm), go to step 3.
3. If measurement of step 2 was less than specified, turn three nuts (11) an equal amount to left until
correct measurement is obtained. If measurement was more than specified, turn nuts (11) an equal
amount to right until correct measurement is obtained.
Pack pilot bearing (8) with GAA grease and install in flywheel bore (9).

NOTE
Ensure clutch disc hub and pilot bearing are alined for proper
installation of transmission input shaft.
2. Use clutch alinement tool to position clutch disc (7) and pressure plate (2) on flywheel (1) with long
end of drive hub (6) away from flywheel (1).
3. Install cover (5) on flywheel (1) with twelve new lockwashers (3) and screws (4). Tighten screws (4)
