Assembling Axle Housing
1. Coat mating faces of two housings (A) and (B) with
sealant and attach selected shim to face of housing (B).
Put the two housings together and fasten them by
tightening bolts to following torque value:
Torque specification
2. Fit ball bearings to out end of each differential shaft,
then mount pinion (14T) and retain pinion by installing
circlip. The ball bearings have a groove cut in the end
faces of the inner and outer races. Be sure to position
the bearing to its grooved end is on inner side as shown.
3. Install o-rings to spacers. Insert differential shafts
through spacers then install differential shaft and spacer
to each axle housings.
Assembling Gear Case and Final Case
1. Use tool TOR4039 to install bushing into final case.

it to final case, making sure the seal is properly aligned.
NOTE: The steel part of this oil seal is so thin that the
seal can distort at the time of installation.
3. Insert final drive shaft into gear case, bringing its large
diameter end to top side and fitting pinion (14T) onto
splined end. Install inner race of upper tapered roller
bearing as shown.
4. Fit bearing out race into gear case. Apply sealant to
mating face of holder and secure to case by tightening
bolts to following torque value:
Torque specification
NOTE: Be sure to wrap each bolt with sealing tape
before installation.
5. Attach final case to gear case while fitting pinion (15T)
onto splined end of shaft.
6. Install tapered roller bearing. Apply sealant to mating
face of cover and secure cover to final case. Tighten
bolts to above listed torque value:
7. Wrap drain plug with sealing tape and install in bottom
cover.
8. Turn final case around gear case by hand and check
for smooth rotation.
