NOTICE:
SBe careful not to damage the O−ring.
SBe careful not to damage the lip seal of the piston.
12. INSTALL UNDERDRIVE CLUTCH RETURN SPRING
SUB−ASSY
(a) Install the return spring to the underdrive clutch drum.
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 underdrive clutch drum.
NOTICE:
Be careful not to damage the lip seal of the clutch balancer.
(d) Place SST on the clutch balancer and compress the pis-
