10) Remove the 1st driven gear, 2nd driven gear
bushing, gear and hub using ST1 and ST2.
NOTE:
If replace the gear or hub assembly as necessary,
use the new gear & hub assembly as a unit. Do not
attempt to disassemble if at all possible because
they must engage at a specified point. If they
should be disassembled, mark engagement point
beforehand.

US ton, 1.0 Imp ton).
NOTE:
 Attach a cloth to the end of driven shaft to pre-
vent damage.
 When press fitting, align the oil holes of shaft and
bush.

8) Position the woodruff key in groove on the rear
of driven shaft. Install the 5th driven gear onto driv-
en shaft using ST and press.
CAUTION:
Do not apply load in excess of 10 kN (1 ton, 1.1
US ton, 1.0 Imp ton).
ST 499277200 INSTALLER9) Install the lock washer. Install the lock nut and
tighten to the specified torque using ST.
ST 499987300 SOCKET WRENCH (50)
Tightening torque:
260 N·m (26.5 kgf-m, 192 ft-lb)
NOTE:
 Stake the lock nut at two points.
 Using the spring balancer, check that starting
torque of roller bearing is 0.1 to 1.5 N (0.01 to 0.15
kgf, 0.02 to 0.33 ft).
10) Install the roller bearing onto drive pinion.
NOTE:
When installing the roller bearing, note its direc-
tions (front and rear) because the knock pin hole in
outer race is offset.

E: INSPECTION
Disassembled parts should be washed clean first
and then inspected carefully.
1) Bearings
Replace the bearings in the following cases:
 Bearings whose balls, outer races and inner rac-
es are broken or rusty.
 Worn bearings
 Bearings that fail to turn smoothly or make noise
when turned after gear oil lubrication.
 The roller bearing on the rear side of the drive
pinion shaft should 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
2) Bushing (each gear)
Replace the bushing in the following cases:
 When the sliding surface is damaged or abnor-
mally worn.
 When the inner wall is abnormally worn.
3) Gears
 Replace the gears with new ones if their tooth
surfaces are broken, damaged, or excessively
worn.
 Correct or replace if the cone that contacts the
baulk ring is rough or damaged.
 Correct or replace if the inner surface or end face
is damaged.4) Baulk ring
Replace the ring in the following cases:
 When the inner surface and end face are dam-
aged.
 When the ring inner surface is abnormally or par-
tially 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 insert is scored or abnormally worn down.
5) Shifting insert key
Replace the insert if deformed, excessively worn,
or defective in any way.
6) Oil seal
Replace the oil seal if the lip is deformed, hard-
ened, 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.

1. THRUST BEARING PRELOAD
1) Select the adjusting washer No. 1 so that dimen-
sion (H) is zero through visual check. Position the
washer (18.3×30×4) and lock washer (18×30×2)
and install the lock nut (18×13.5).
2) Using the ST1, ST2 and ST3, tighten the lock nut
to specified torque.

4) If the starting torque is not within specified limit,
select a new adjusting washer No. 1 and recheck
starting torque.
