10. INSTALL FORWARD CLUTCH RETURN SPRING
SUB-ASSY
(a) Install the return spring to the input shaft.
NOTICE:
Installing the spring sub- assembly, check all of the
springs are fit in the piston correctly.
(b) Coat the clutch balancer with ATF.
(c) Install the clutch balancer to the input shaft.
NOTICE:
Be careful not to damage the lip seal of the forward
clutch balancer.
Install the clutch balancer carefully not to have a
pinching and any other defects at the sealing lip.
Apply enough ATF to the sealing lip prior to assem-
bling.
(d) Place SST on the clutch balancer, and compress the
clutch balancer with a press.
SST 09387-00020
(e) Install the snap ring with a snap ring expander.
(f) Be sure the end gap of the snap ring is not aligned with
the spring retainer claw.
NOTICE:
Stop the press when the spring sheet is lowered to the
place 1 - 2 mm (0.039 - 0.078 in.) from the snap ring
groove.
This prevents the spring sheet from being deformed.
Do not expand the snap ring excessively.
(g) Set the end gap of the snap ring in the piston shown in the
illustration.
NOTICE:
The end gap of the snap ring should not coincide with any
of the stoppers.

If the piston stroke is less than the minimum, parts may have
been assembled incorrectly. Check and reassemble again.
If the clearance is not standard, select another flange.
HINT:
There are 5 different flanges in thickness.
Flange thickness: mm (in.)
