REAR AXLE
hub, plain washer and castellated
nut, tightening this to a torque
of 125-145 lbs. ft. (17.29-19.71 kg.
metres) and securing it with a
split pin.
(iv) Examine the inner oil seal and,
if a replacement is necessary,
proceed as shown in Fig.
8. Oil
seal renewal is recommended in
all cases of axle overhaul.
(v) Replace the original shim pack
over the spigoted portion of the
axle sleeve, followed by the brake
backing plate.
(vi) Again exercising care in the case
of the inner oil seal, thread the
assembled axle shaft through the
seal and into the axle casing. After
locating the shaft splines in those
of the sun wheel, secure the
bearing housing by inserting arid
tightening six setscrews with
lock-
plates.

Checking axle shaft end float.
Axle Shaft End-Float
The specified axle shaft end-float is
0.004"-0.006'' (0.102-0.152
mm.).
This can be checked by mounting a
dial indicator on the backing plate, as
shown in Fig.
9, then moving the hub

towards and away from the axle casing.
The dial indicator will then record the
axle shaft end-float.
Adjustment is effected by adding to,
or subtracting from the shim pack
interposed between the axle sleeve
flange and the brake
backing plate,
thus increasing or decreasing respec-
tively the axle shaft end-float.
Important.--In addition to the exis-
tence of the specified end-float, it
is important that the thrust block
which separates the inner ex-
tremities of the two axle shafts,
should have a clearance on the
cross-pin, as shown in Fig. 10.
To ensure centralization of the
thrust block with the cross-pin,
the shim packs behind both back-
ing plates will be approximately
of equal thickness.
(vii) Replace brake drum, road wheel
and, before removing the lifting
jack, it is essential to grease the
hub bearing.
4. DIFFERENTIAL AND PINION
ASSEMBLIES
Except for the addition of a thrust block
(item 15, Fig. 13), the crown wheel and
pinion assemblies remain the same as fitted
to the previous axle. Therefore, instruc-
tions for the servicing and adjustment of
these assemblies are unaltered.
