Caution
1.The gasket, O-ring, and oil seal should never be reused.Whenever they have been removed, they must be
replaced with new ones. (Note: The rubber used in theoil level gauge does not require replacement.)
2. Never use grease other than petrolatum.
3.Be sure to apply ATF to the friction elements and rotary
and sliding surfaces before reassembly.
A new clutch disc and brake disc should be dipped inATF for more than 2 hours before installation.
4. Do not use sealant or adhesive for gaskets.
5.When replacing a bushing, replace the whole assemblycontaining that bushing.
6.Do not use cotton work gloves or waste cloth for the
reassembly job. Use nylon cloth or paper towel if
necessary.7. Replace oil in the cooler.
(I) Using the special tool, press-fit the drive shaft oil seal into
position.
(2) Using the special tool, press-fit the outer race into the
transaxle case.
(3) Install the transfer shaft.

(4) Place 10 mm-long t.39 in.), 1.6 mm-dia. (.06 in.) solders at
the locations shown of the output bearing retainer and
install the outer race.
(5) Install the output bearing retainer and tighten bolts to
specification.
(6) Loosen the bolts and remove the output bearing retainer.
(7) Remove the outer race from the output bearing retainer and
remove the solders. If the solders are not crushed, use
larger dia. (3 mm or
.12 in.) solders to repeat steps (4) to (6).
Measure the thickness of the solders crushed with a
micrometer and select a spacer to obtain the specified
preload.Standard value: 0.075

retainer mounting bolts to specification.(I 1)lnsert the output flange into the case and fit the snap ring
over the periphery of the bearing.
