Section G (Rear Axle)
Whenever a replacement oil seal is fitted, the
outside of the cage should be coated with a liquid
jointing compound before the seal is pressed into
position. These seals operate most effectively in
one direction, and thus they should be fitted with
the lip and spring facing the rear axle. They are
easily removed and replacements can be driven into
P?Sitlon, using a hollow drift of correct diameter.
HUB OIL
RETAINERS (See Figs. 9 and 10)
An oil splash guard which consists of an outer ring
sandwiched between the rear hub bearing outer
track and its abutment in the axle casing, over­
lapping an inner ring retained between the bearing
inner track and its abutment on the axle shaft, is
supplemented by an oil seal located in a housing
adjacent to the inside face of the brake backing
plate, the lip of this seal operating on the machined
outer diameter of the rear hub. An effective oil
sealing arrangement is thus obtained.
The oil seal is replaceable after removal of the rear
hub (described in a later paragraph), and the five
nuts and bolts passing through the dust shield, seal
housing, brake backing plate and axle casing flange.
AXLE SHAFT-To remove and refit
To remove
It is most Important that those responsible for the
repair of this rear axle should know that the design
of the rear hub bearing assembly is such that
serious damage will result from any attempt to
remove an axle driving shaft by any method other
than the followlng:-
Remove road wheel.
Remove all road dirt from brake backing plate
around Its fixing to the axle tube flange.
Remove setscrews securing brake drum.
Remove brake drum.

Release brake connections from rear of backing
plate.
Protect brake connections against the ingress
of foreign matter.
Remove nuts and bolts securing brake backing
plate to flange on axle casing.
Fit the axle shaft removing tool (VLC. No. RG.16)
over the four wheel studs and secure it by the nuts.
Move the sliding weight sharply along the shaft of
the tool against its outer abutment in order to draw
the shaft out of the axle casing.
Remove the shaft complete with brake backplate,
oil seal, dust excluder and hub.
Remove outer ring of splash guard from bearing
recess. (See item 36, Fig. 10.)
To refit
Ensure that the brake backplate and axle casing
flange arou'nd the bearing recess are free from
dirt. It is essential that the bearing remains clean
during assembly.
Flt outer member of splash guard Into bearing
recess (Fig. 9) with recessed centre inwards. A
little grease smeared around the housing will help
to keep the guard in place whilst entering the shaft
and bearing.
Pass the shaft Into the casing and enter the splines
into those of the axle shaft end wheels.
Carefully drive the shaft assembly Inwards until the
bearing Is fully home in its recess.
Fit the five bolts through the dust excluder, oil seal
casing and backplate. Turn the hub to centralize
the oil seal before tightening the nuts. Re-connect
brake hoses, fit brake drum and road wheel.
Bleed brakes, as described in Section K of this
manual under the heading "Bleeding the System."
