Differential Pinion Shaft
b. On the case or cover when dis-
assembled. However, when press-
ing
the bearing on the cover, a
block of wood or fibre must be
used as shown in Fig. 49 in order
to avoid damage to the cover.
ASSEMBLY
1.
Lubricate all parts with ESW-
M2C-119-A locker lubricant during
assembly.
2. Mount the differential case in
a soft jawed vice and place a side gear
thrust washer and side gear in the
counter bore of the case.
3. Install the pinion thrust wash-
ers and place the pinion gears on the
side gear aligning the holes in the
washers and gears with the holes in
the case.
4. Install the centre block so that
the shaft holes are aligned with the
holes in the pinion gears and case.
The centre block has two mach-
ined sides and two rough sides.
5. With a brass drift, drive in the
long pinion shaft from the outside of
the case aligning the lock pin holes in
the shaft with the holes in the case.
The centre block should be posi-
tioned so the long shaft is driven
through the rough side and short
shafts driven through the mach-
ined side (Fig. 50).
6. With a suitable drift, install
the shaft lock pins. Make sure the
pinion and side gears move freely.
7. Place the four pre-load springs
in the holes provided in the centre
block.
8. Position a pre-load plate over
the four springs, making sure the
springs
are properly seated. The pre-
load plate straddles the centre block
over its narrower or machined width.
9. Mount the differential cover in
a soft jawed vice or holding fixture.
10. Insert shim(s) of 0.050 total
thickness in the cover cavity.
11. When new clutch plates are
used, soak the plates in ESW-
