(2) Remove the snap ring.
SERVICE POINTS OF REASSEMBLY6. INSTALLATION OF SNAP RING
(1) Compress the return spring with the special tool.
(2) Install the snap ring.
5. INSTALLATION OF CLUTCH PRESSURE
PLATE/3.CLUTCH
DISC/P. CLUTCH REACTION PLATE
(1) Assemble the clutch pressure plate, clutch plate and
clutch reaction plate, arranging them by the missing
tooth [See figure
@I.
NOTEThis is so the automatic transmission fluid escapes
easily and there is good cooling of the plate and disc.
(2) Assembly the plates so the beveled side is as shown inthe figure.
(3) Assemble so the thickest plate (clutch reaction plate) is
on the snap ring side.
1.SELECTION OF SNAP RING
Check clearance between the snap ring and clutch reaction
plate. To check the clearance, hold entire circumference ofthe 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:
0.7-0.9 mm (.028-.035 in;)
0.8-1.0 mm (.032-.039 in.)
