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”.
NOTE:
Measure with bearing cone and thrust washer re-
moved.
6) Calculate the space “t” using the following equa-
tion: t = X−W+0.2 to 0.3 mm (0.008 to 0.012 in)
7) Select the nearest washer in the following table:
Standard clearance between thrust washer and
taper roller bearing:
0.2 — 0.3 mm (0.008 — 0.012 in)
NOTE:
Set the clearance within standard clearance.
