1.
Check
the
bevel gear and
pinion
and differen-
tial gears and
pinions
for
excessive
tooth
wear.
2. Measure
the
thickness
of
the
thrust
washers
(Items 15 and
17, Fig.
8.11115)
for
differential
gears and
pinions
and the service wear
of
the
pinion bushes.
Notice
that
if
the
bushings
are renewed they require reaming
after
fitting
to
ensure
the
correct
assembly clearance.
3. Check the
functional
efficiency
of
the
tapered
roller
bearings and
of
the
oil
seals
(Item
7)
of
differential
axle shafts.
4. Check the running surface
of
the
differential
lock
collar
and the
functional
efficiency
of
the
locating
hollow
pins.
5. Check
the
differential
lock
return spring
characteristics
versus the
specifications
given on
the
table
of
data.
BEVEL GEAR AND DIFFERENTIAL ASSEMBLY
Reverse the sequence
of
disassembly,
see
the
Fig.

and take
good
note
of
the

1. Smear grease over
the
differential
pinion
washers (Item 17, Fig.
6.11115).
2. Install
the
two
special head
bolts
(Item
C2)
securing the bevel gear
to
the
differential
carrier in
the
holes
at
both
ends
of
the
dif-
ferential
pinion
shaft
(Item
19).
3.
Fit the
differential
lock
return spring.
4.
