MANUAL TRANSMISSION AND DIFFERENTIAL

Transfer Case and Extension Case Assembly

9. Transfer Case and Extension 

Case Assembly

A: REMOVAL

1) Remove the manual transmission assembly
from vehicle. <Ref. to 5MT-30, REMOVAL, Manual
Transmission Assembly.>
2) Remove the back-up light switch and neutral po-
sition switch. <Ref. to 5MT-40, REMOVAL, Switch-
es and Harness.>
3) Remove the transfer case with extension 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 transfer case.

2) Remove the bearing outer race from extension
case.

3) While pressing the bearing outer race horizontal-
ly, turn the driven shaft ten rotations.
4) Measure the height “W” between transfer case
and taper roller bearing on the transfer driven gear.

5) Measure the depth “X” on bearing insertion part
of extension case.

NOTE:
Measure with bearing outer race and thrust washer
removed.

6) Calculate the thickness of thrust washer “t” using
following equation.
t = X 

− W + 0.2 to 0.3 mm (0.008 to 0.012 in)

7) Select the washer of nearest value in the follow-
ing table:

Standard protrusion amount of taper roller 
bearing outer race:

0.2 — 0.3 mm (0.008 — 0.012 in)

NOTE:
Be sure that the protrusion amount is within stan-
dard.

8) Fit the thrust washers on transfer drive shaft.
9) Install the bearing outer race into extension
case.
10) Measure the depth “S” between transfer case
and center differential.

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

12) Calculate the thrust washer “U” using following
equation.
U = 30 mm (1.18 in) 

− S − T − 0.15 — 0.35 mm

(0.0059 — 0.0138 in)

13) Select a suitable washer in the following table:

Standard clearance:

0.15 — 0.35 mm (0.0059 — 0.0138 in)

14) Fit the thrust washer on center differential.
