B. TO ASSEMBLE
1. Sub-assemble the inner rim of taper roller bearing
(23) on 8 bevel pinion shaft (22).
2. Sub-assemble the outer rim of taper roller bearing
(23), shim (24) and the outer rim of taper roller bear-
ing (25) on differential gear case ass'y (5).
3. Install the sub-assembled 8 bevel pinion shaft (22)
on differential gear case ass'y (5).
4. Support the gear side of 8 bevel pinion shaft (22)
and knock the inner rim of taper roller bearing (25)
into the opposite side.
5. Install O-ring (26) on the inner bore of oil seal collar
(27) and apply grease to fix on 8 bevel pinion shaft
(22) with a replacing tool.
6. Apply grease on the inner rim of oil seal (28) to
install on the outer rim of oil seal collar (27) with a
replacing tool.
7. While tightening nut (29) to allow the turning torque
of 8 bevel pinion shaft (22) to be 0.13 ~0.17 kgf·m,
apply caulking after the adjustment. Turning torque:
0.13 ~0.17 kgf·m (1.27 ~ 1.667 N·m, 0.94 ~ 1.23
lbf·ft)
8. Sub-assemble front differential case (14) section.
• Install shim (18), differential side gear (17), differ-
ential side washer (16), differential pinion (15) in
due order and then differential pinion shaft (19) in-
side front differential case (14).
• When assembling differential pinion
shaft (19), let the section area located
opposite to 27 bevel gear (12).
CAUTION
Decide such installing shim (18) as to
allow backlash of differential pinion
(15) and differential side gear (17) to
be 0.1 ~ 0.3 mm (0.0039 ~ 0.0118 in.)
• Install parallel pin (21) on differential
pinion shaft (19).
- Install parallel pin (20) on front
differential case (14).
- Install shim (18), differential side
gear (17) on the inner bore of 27
bevel gear (12) and tighten 27
bevel gear (12) and front differen-
tial case (14) with 6 UBS bolts (13)
as aligned with the position of
parallel pin (20).
• Apply adhesive on the UBS bolt (Three
Bond 1324B) and fix at a tightening
torque of 3.0 ~ 3.5 kgf·m (29.4 ~ 34.3
CAUTION
