8. INSPECT MULTIPLE DISC CLUTCH CLUTCH HUB
(a) Using a caliper gauge, measure the inside diameter
of the forward clutch hub bush.
Standard inside diameter:
23.025 to 23.045 mm (0.9065 to 0.9073 in.)
Maximum inside diameter:
23.09 mm (0.9091 in.)
NOTICE:
• When the diameter is over the maximum,
replace the multiple disc clutch hub with a
new one.
• Check the contact surface of the bush in the
direct clutch shaft. If any scratch or discolor
is identified, replace the direct clutch sub-
assembly with a new one.
If the inside diameter is greater than the maximum,
replace the forward clutch hub.

(c) Coat the 1st and reverse brake piston with ATF, and
install it to the transaxle.
(d) Install the 1st and reverse brake return spring to the
1st and reverse brake piston.
(e) Using SST, a press and snap ring expander, press
the piston return spring and snap ring to the
transaxle.
NOTICE:
• Stop the press when the spring sheet is
lowered to the place 1 to 2 mm (0.039 to 0.078
in.) from the snap ring groove, preventing the
spring sheet from being deform.
• Do not expand the snap ring excessively.
