8. Preparation for Overhaul
A: PROCEDURE
1) Clean oil, grease, dirt and dust from the trans-
mission.
2) Using the TORX
®
bit T70, remove the drain plug
of the transmission gear oil, and drain the transmis-
sion gear oil completely.
3) Using the TORX
®
bit T70, tighten the transmis-
sion gear oil drain plug.
NOTE:
Use a new gasket.
Tightening torque:
44 N·m (4.5 kgf-m, 32.5 ft-lb) (Aluminum gas-
ket)
70 N·m (7.1 kgf-m, 51.6 ft-lb) (Copper gasket)
4) Attach the transmission to ST.

5) Apply oil to rotating parts before assembly.
6) All disassembled parts, if to be reused, should
be reinstalled in the original positions and direc-
tions.
7) Gaskets, lock washers and lock nuts must be re-
placed with new ones.
8) Apply liquid gasket to the specified areas to pre-
vent leakage.

9. Transfer Case and Extension
Case Assembly
A: REMOVAL
1) Remove the manual transmission assembly
from the vehicle. <Ref. to 5MT-24, REMOVAL,
Manual Transmission Assembly.>
2) Remove the back-up light switch neutral position
switch. <Ref. to 5MT-35, REMOVAL, Switches and
Harness.>
3) Remove the transfer case together with the ex-
tension case assembly.
4) Remove the shifter arm.
5) Remove the extension case assembly.
B: INSTALLATION
1) Install the center differential and transfer driven
gear into the transfer case.
2) Remove the bearing outer race from the exten-
sion case.
3) While holding the bearing outer race horizontal-
ly, rotate the driven shaft for ten turns.
4) Measure the height “W” between transfer case
and taper roller bearing on the transfer driven gear.

5) Measure depth “X” on bearing insertion part of
the extension case.
NOTE:
Measure with bearing outer race and thrust washer
removed.
6) Calculate the thrust washer thickness “t” using
the following calculation.
t = X – W + (0.15 — 0.25 mm (0.006 — 0.010 in))
7) Select the washer with the nearest value in the
following table.
Preload (standard protrusion) of the taper roller
bearing:
0.15 — 0.25 mm (0.006 — 0.010 in)
NOTE:
Be sure that the preload is always within the stan-
dard.
8) Fit the thrust washers on the transfer drive shaft.
9) Install the bearing outer race into the extension
case.
10) Measure the depth “S” between transfer case
and center differential.

11) Measure the height “T” between the extension
case and transfer drive gear.

NOTE:
Thickness of ST: 15 mm (0.59 in)
12) Calculate the thrust washer thickness “U” using
the following calculation.
U = S + T – 30 mm (1.18 in) [Thickness of ST]
