MANUAL TRANSMISSION AND DIFFERENTIAL

Input Shaft Assembly

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 ex-
cessively worn, bent or defective in any way.
9) Measure the clearance between snap ring and
ball bearing using thickness gauge.

Clearance:

0 — 0.12 mm (0 — 0.0047 in)

If the measurement is not within specification, se-
lect a suitable snap ring.

F: ADJUSTMENT

1) Place transmission main shaft assembly and in-
put shaft on transmission main case without shim.
2) The proper number of shim can be determined
as follows:
D = A

− (B + C)

A: Main case length (353 mm (13.90 in))
B: Input shaft complete length
C: Main shaft assembly length

NOTE:
The thickness of shim is 0.45 to 0.55 mm (0.0177 to
0.0217 in).

A: REMOVAL

1) Remove the manual transmission assembly
from vehicle. <Ref. to 5MT-30, REMOVAL, Manual
Transmission Assembly.>
2) Remove the transfer case with extension case
assembly. <Ref. to 5MT-43, REMOVAL, Transfer
Case and Extension Case Assembly.>
3) Remove the transmission case. <Ref. to 5MT-
55, REMOVAL, Transmission Case.>
4) Remove the drive pinion shaft assembly.

NOTE:
Use a hammer handle, etc. to remove if too tight.

B: INSTALLATION

1) Remove the differential assembly.
2) Use hypoid driven gear of its match number cor-
responding with upper one on the drive pinion (A).
The figure (B) shows a number for shim adjust-
ment. If no number is shown, the value is zero.

3) Place the drive pinion shaft assembly on the
transmission main case RH without shim and tight-
en the bearing mounting bolts.
4) Inspect and adjust the ST.

NOTE:
• Loosen the two bolts and adjust so that the scale
indicates 0.5 correctly when the plate end and the
scale end are on the same level.
• Tighten the two bolts.

and read the value at the point where it matches
with the end face of drive pinion.

7) The thickness of shim shall be determined by
adding the value indicated on drive pinion to the
value indicated on the ST. (Add if the number on
drive pinion is prefixed by +, and subtract if the
number is prefixed by

−.)

9) Install the differential assembly. <Ref. to 5MT-
84, INSTALLATION, Front Differential Assembly.>
10) Set the transmission main shaft assembly and
drive pinion assembly in position. (So there is no
clearance between these two when moved all the
way to the front). Inspect the suitable 1st — 2nd,
3rd — 4th and 5th shifter fork so that the coupling
sleeve and reverse driven gear are positioned in
the center of their synchronizing mechanisms.
<Ref. to 5MT-81, INSPECTION, Drive Pinion Shaft
Assembly.>
11) Install the transmission case. <Ref. to 5MT-57,
INSTALLATION, Transmission Case.>
12) Install the transfer case with extension case as-
sembly. <Ref. to 5MT-43, INSTALLATION, Trans-
fer Case and Extension Case Assembly.>
13) Install the manual transmission assembly to ve-
hicle. <Ref. to 5MT-30, Manual Transmission As-
sembly.>

C: DISASSEMBLY

NOTE:
Attach a cloth to the end of driven shaft (on the fric-
tional side of thrust needle bearing) to prevent
damage during disassembly or reassembly.
1) Unlock the caulking of lock nut. Remove the lock
nut using ST1, ST2 and ST3.
