HUB OIL RETAINERS (Figs. I and 3)
An oil splash guard (38), which consists of an outer
ring overlapping an inner ring (37), is supplemented
by an oil seal (39). The oil seal Is replaceable
after removal of the rear hub (described in a later
paragraph), and the three plain bolts and two dowel
bolts passing through the dust shield, seal housing
(40), brake backing plate and axle casing flange.
Care should be taken on replacing these bolts
that they are fitted in the correct holes.
The hub may be removed for oil seal replacement
without removing halfshaft using Tool RG. 188-B
as shown in Fig. 2.
AXLE SHAFT-To remove and refit
Rapier
cars
have unequal length axle
shafts.
The
longer shaft
is
fitted
to
the right-hand side
of
the
car, the short shaft Is fitted
to
the left-hand side.
Alpine cars have shafts
of
equal length.
The drive shafts (and differential wheels)
on
early
Alpine and Rapier cars have 17 splines, Later cars
have shafts (and wheels) with
25
splines.
Shafts can
be
identified by the
letter
stamped
on
the
outer
end of the shaft as follows :-

Removing hub for
oil
seal renewal
Cars with disc wheels
Flt the axle shaft removing tool (VLC .No. RG.16A)
and adaptor (RG.
I
6A-4 or
188-B)
over the four
wheel studs and secure it by the nuts.
Cars with centre-lock wire wheels
Screw the four extension legs (VLC .No. RG. I 6A-5)
Into the brake drum securing holes. Flt the axle
shaft removing tool and secure It with 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 back plate,
oil seal, dust excluder and hub.
Remove outer ring of splash guard from bearing
recess. (See Item 38, Fig. 3).
To refit (Fig. 3)
Ensure that the brake backplate and axle casing
flange around the bearing recess are free from
road dirt. It is essential that the bearing remains
clean during assembly.
Fit outer member of splash guard (38), into bearing
recess (Fig. I), 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 ease the splines
into those of the axle shaft end wheels (19).
Pushing the shaft Inwards, enter the bearing In Its
recess and carefully drive the assembly into position
until the bearing outer face is flush with the end of
the recess.
Ensuring that all remaining parts are clean, fit back­
plate, oil seal and housing and dust shield to axle
casing flange. Flt the five bolts, nuts and spring
washers.
