/ 3.
CLUTCH PLATE / 2. CLUTCH REACTION PLATE
(1) When installing the clutch pressure plate, clutch plate,
and clutch reaction plate, align the areas where one
tooth is missing [indicated by @I.
NOTE
This ensures that the automatic transmission fluid
escapes well and the plate and disc are cooled
efficiently.
(2) Install the plates so that the shear droop side of each
plate is located as shown.
(3) Make sure that the thickest plate (clutch reaction plate)
is located on the snap ring side.
1. SELECTION OF SNAP RING
(1) Check clearance between the snap ring and clutch
reaction plate. To check the clearance, hold entire
circumference of the clutch reaction plate down with 50
N (11
Ibs.) force. If clearance is out of standard value,
select a snap ring to obtain the standard value.
Standard value: 0.8
- 1.0 mm (.032 - .039 in.)
