to
.006".
Add or subtract
necessary
shims
to
reach this
figure.
f.
Remove side

and repeat procedure
with

washers.
9.
Install
remaining side
gear
and

pack
with
correct shims in
case.
10.
Place
pinion
gears
on side
gears
and rotate
into
correct position.
11.
Compress the preload springs
with
a 2" C
clamp,
as shown in Fig.
4B-10,
and drive the preload
retainer and springs between side
gears.
12.
Insert thrust washers behind
pinion
gears.
13.
Install

14.
Check side
gear
splined hole to be certain
it
is in
line
with
hole in the preload spring retainer.
The spring retainer can be moved

The
following
procedure Is to be used In
assem-
bling
both the two
pinion
differential
and the
four
pinion
differential.
Slight
differences are noted In
steps
4 and 5.
CAUTION:
When assembling unit, use
axle
shafts
as
mounting tools to
assure
proper
gear and cone
spline
alignment. Do not
ignore
this
procedure
or
it
will
be impossible to
install
shafts at
final
as-
sembly. Attempting to
force
shafts into position
may
result
in damage to

1. Clamp one axle shaft in vise,
allowing
three
inches to extend above vise jaws. Then place cap
half
of
differential
case
over extended axle shaft,
with
interior
of
case
facing up (Fig. 4B-11).
2.
Install
proper cone over axle shaft splines,
seating it
into
position in cap
half
of
case.
NOTE:
Be
certain
that each cone is
installed
in
proper
case
half,
since
tapers and
surfaces
become
matched
and their positions
should
not be changed.
3. If
unit
was
originally
assembled
with
shims
located
between side
gears
and
cones
for backlash
adjustment, reinstall side
gear
with
shim so that
gear
may
seat
on shim. If
unit
was
originally
as-
sembled
without
shims,
reassemble
same
way.
