REMO
V A L
OF DIFFERENTIAL RING
GEAR AN D CASE ASSEMBLY
1. After removal of both axle shafts (par.
5-8), remove
differential
side gears and thrust
washers from case to pr event them
falling
out
and being damaged.
2.
If
ring
and pinion
gear set has been oper-
ating
quietly
and is to be
reinstalled,
it is ad-
visable to wash lubricant from between gear
teeth and check existing gear lash by means
of a
dial
indicator, so that t
he
same lash ca
n
be used when parts are reinstalled, to avoid
changing gear tooth contact. See paragraph
5-
23, steps 8 and 9.
CAUTION:
Backlash will be reduced w
hen
pinion is locked by prying up with a bar if
there is excessive pinion lift due to worn bear-
ings. See paragraph
5-11,
step 2.
3.
Mark
the
differential
bearing caps so they
can be
reinstalled
in original
positions
on the
carrier. Interchanging the caps will cause dam-
aged threads
because
caps are threaded in pro-
duction
while bolted to carrier.
4. Remove bearing adjuster locks, loosen one
adjuster, support the differential gear and case
assembly while removing bearing caps and
adjusters, then lift
differential
assembly and
bearing races
out
of carrier.

REMOVAL AND DISASSEMBLY OF
PROPELLER SHAFT AND PINION
ASSEMBLY
1.
If
ring and pini on gear set has been
oper-
ating
quietly and is to be
reinstalled, it
is
advisable
to check the
pinion setti ng
a
fter r
e-
moval
of differential case (par.
5-10) so
that
the same
setting
can be used when parts are
reinstalled to avoid changing gear tooth con-
tact. See paragraph
5-21.
2. At this point it may be desirable to t
est
pinion shaft
bearing
wear without removing
pi
nion shaft. Install

and mount indicator to

with indicator
stem
as near
vertical
as
possible.
See
figure
5-5. Pry up
on
pinion gear with bar
a number of times while observing indicator
reading. A reading in excess of .0015" indicates
that bearing is worn enough to produce noisy
gear operation.
3. Loosen lock nuts and remove three pinion
bearing sleeve lock screws from housing.
