1. General

B3M0037A
B: PRECAUTIONS
1) The following job should be followed before disassem-
bly:
(1) Clean oil, grease, dirt and dust from transmission.
(2) Remove drain plug

1to drain oil. After draining,
retighten it as before.
CAUTION:
Replace gasket with a new one.
Tightening torque:
44±3 N⋅m (4.5±0.3 kg-m, 32.5±2.2 ft-lb)
G3M0517
(3) Attach transmission to ST.
ST 499937100 TRANSMISSION STAND SET
2) Rotating parts should be coated with oil prior to assem-
bly.
3) All disassembled parts, if to be reused, should be rein-
stalled in the original positions and directions.
4) Gaskets and lock washers must be replaced with new
ones.
5) Liquid gasket should be used where specified to pre-
vent leakage.
6) Fill transmission gear oil through the oil level gauge
hole up to upper point level gauge.
C: INSPECTION
Disassembled parts should be washed clean first and then
inspected carefully.
1) Bearings
Replace bearings in the following cases:
Bearings whose balls, outer races and inner races are
broken or rusty.
Worn bearings
Bearings that fail to turn smoothly or make abnormal
noise when turned after gear oil lubrication.
B3M0038A
The ball bearing
3on the rear side of the drive pinion shaft


2should be checked for smooth rotation before the drive
pinion assembly is disassembled. In this case, because a
preload is working on the bearing, its rotation feels like it is
slightly dragging unlike the other bearings.
Bearings having other defects

3-1SERVICE PROCEDURE
1. General

2) Bushing (each gear)
Replace the bushing in the following cases:
(1) When the sliding surface is damaged or abnormally
worn.
(2) When the inner wall is abnormally worn.
3) Gears
(1) Replace gears with new ones if their tooth surfaces
are broken, damaged, or excessively worn.
(2) Correct or replace if the cone that contacts the
baulk ring is rough or damaged.
(3) Correct or replace if the inner surface or end face
is damaged.
B3M0039A
4) Baulk ring
Replace the ring in the following cases:
When the inner surface and end face are damaged.
When the ring inner surface is abnormally or partially
worn down.
If the gap between the end faces of the ring and the gear
splined part is excessively small when the ring is pressed
against the cone.
Clearance

A:
0.5 — 1.0 mm (0.020 — 0.040 in)
When the contact surface of the synchronizer ring

4
insert is scored or abnormally worn down.
B3M0040A
5) Insert
5(shifting)
Replace the insert if deformed, excessively worn, or defec-
tive in any way.

1. General

6) Oil seal
Replace the oil seal if the lip is deformed, hardened,
damaged, worn, or defective in any way.
7) O-ring
Replace the O-ring if the sealing face is deformed,
hardened, damaged, worn, or defective in any way.
8) Gearshift mechanism
Repair or replace the gearshift mechanism if excessively
worn, bent, or defective in any way.
G3M0521
9) Differential gear
Repair or replace the differential gear in the following
cases:
(1) The hypoid drive gear and drive pinion shaft tooth
surface are damaged, excessively worn, or seized.
(2) The roller bearing on the drive pinion shaft has a
worn or damaged roller path.
(3) There is damage, wear, or seizure of the differen-
tial bevel pinion, differential bevel gear, washer, pinion
shaft, and straight pin.
(4) The differential case has worn or damaged sliding
surfaces.
