c. Remove final reduction case from
Stand, and press out drive pinion.
Pay attention to the reduction drive
gear end which protrudes from the
mating surface.
d. Press out the reduction driven gear
and bearing retainer as an ASSY
from the transmission side by press-
ing the driven gear with an appro-
priate size of steel rod or pipe.
During this operation, pay atten-
tion to keep the reduction driven
gear free from interfering with the
case.

2) Check
Wash all parts and carefully inspect
them as follows:
1) Cases
Replace if cracked or damaged.
Repair if a mating surface is scored or
seized.
Replace seized or cocked bushings.
2) Gaskets, oil seals, O-rings
Replace gaskets at every removal.
Replace O-rings if the sealing lips are
folded, torn of deformed.
Replace oil seals if getting loose of
spring, deformation of lip or any other
abnormality are recognized.
3) Bearings
Check bearings for damaged roller face
and abnormal wear.
If necessary, replace bearings as an
ASSY.
Replace bearings which show abnormal
color on the roller face.
4) Gears
If damage or abnormality are recog-
nized on the tooth surface of hypoid
gear, differential gear, reduction gear
and governor gear, replace them with
new ones.
NOTE:
Check the gears carefully, because
worn tooth surface of abnormal tooth
contact, which is difficult to find on
external appearance, will become a
cause of gear noise.
3) Installation
1)
When final reduction components
are disassembled, assemble them prop-
erly.
2) Press thrust bearing retainer with
front bearing cup preset in it and
reduction driven gear into final reduc-
tion case by using Installer
(499427000) and Handle
(498477000).
NOTE:
a. Be sure to align the projection of
retainer flange with the groove of
case.
b. Press the retainer until the end
surface of retainer flange reaches
that of case.
