10. INSTALLATION OF CLUTCH PLATE/*. CLUTCH REAC-
TION PLATE
Assemble the clutch plate and 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.
7. 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:
1.0-1.2 mm (.034-.047 in.)
2. INSTALLATION OF INPUT SHAFT
Align the input shaft oil groove and rear clutch retainer

TFA02682. SELECTION OF SNAP RING
First install the snap ring and then check if the gap between
the snap ring and clutch reaction plate reaches the standardvalue. When measuring the gap, press the circumference
,“i
of the clutch reaction plate firmly with a force of 50 Nm (11
Ibs.). If the gap is outside the standard value, select a snap
ring and adjust until it reaches the standard value.
Standard value:
0.4-0.65 mm (.016-.026 in.)
0.6-0.85 mm (.024-.033 in.)
