Removal
1. Remove transmission assembly, refer to ºMANUAL
TRANSMISSIONº of Section 7B for ºRemoval AND
INSTALLATIONº procedure.
2. Mark the flywheel, clutch cover and pressure plate lug
for alignment when installing.
3. Remove pressure plate assembly (3).
4. Remove driven plate assembly (1) or (2). Use the pilot
aligner 5-85253-001-0 (J-24547) to prevent the
driven plate assembly from falling free.

Inspection and Repair
Make necessary correction or parts replacement if wear,
damage, or any other abnormal condition are found
through inspection.
Pressure Plate Assembly
201RS002
1. Visually check the pressure plate friction surface for
excessive wear and heat cracks.
2. If excessive wear or deep heat cracks are present,
the pressure plate must be replaced.
Pressure Plate Warpage
201RS003
Page 2520 of 3573

CLUTCH7C±11
1. Use a straight edge and a feeler gauge to measure
the pressure plate friction surface flatness in four
directions.
2. If any of the measured values exceeds the specified
limit, the pressure plate must be replaced.
Pressure Plate Warpage
Limit: 0.3 mm (0.012 in)
Clutch Cover
201RS004
1. Visually check the entire clutch cover for excessive
wear, cracking, and other damage.
2. The clutch cover must be replaced if any of these
conditions are present.
Clutch Set Force
201RS005
1. Invert the pressure plate assembly.2. Place a new driven plate over the pressure plate. A
metal sheet with ªAº thickness of 8.3 mm (0.327 in)
may be used in place of the driven plate.
3. Compress the pressure plate assembly until the
distance ªBº becomes 12 mm (0.472 in).
4. Note the pressure gauge reading.
5. If the measured value is less than the specified limit,
the pressure plate assembly must be replaced.
Clutch Set Force
Standard: 7208 N ( 1621 lb)
Limit: 6468 N (1454 lb)
Diaphragm Spring Finger Height
201RW009
Legend
(1) Release Side
1. Place a new driven plate or a 8.3 mm (0.327 in)
spacer beneath the pressure plate.
2. Fully compress the pressure plate and diaphragm
spring.
3. There are two ways to do this.
4. Use a bench press to press down on the assembly
from the top.
5. Tighten the fixing bolts.
NOTE: Preload on diaphragm spring finger must be 49 ±
98 N (11 ± 22 lb) in direction of release, when clutch cover
assembly is bolted to the flywheel.
6. Measure the spring height from base to spring tip ªAº.
If the measured value exceeds the specified limit, the
pressure plate assembly must be replaced.
Diaphragm Spring Finger Height
Standard: 49.9 mm ± 51.9 mm (1.965 in ±
2.043 in)
