The lateral location of the hub bearing is controlled
by a sleeve on the Inner side of the bearing against
which the latter is located by the hub when fully
positioned on its taper.
It Is essential that the hub bearing Is always tightly
compressed between the sleeve and the hub.
Therefore, when fitting a new hub bearing, the
following procedure should be adopted:-
Fit the split bush (part VLC kit RG. I 88A-1) to the
solid ring. Note. It Is not necessary to dismantle
the tool to flt the split bush. The bearing may be
left resting on the tapered portion of the axle shaft
and the split bush Inserted in the solid ring with
the extractor In the fully released position. Alter­
natively, before fitting the split bush, and after
screwing back the extractor centre bolt, the bearing
may be removed between the legs of the extractor.
Slide the assembly over the axle shaft with the
flanged side of the bush away from the spline, until
It butts the sleeve.
Flt the four extension legs, short protector, and
extractor.
Rotate the centre bolt of the extractor until the
sleeve has been pulled
n"
(·8 mm.) In the direction
of the outer end of the axle shaft.
Remove split bush.
Remove axle shaft from tool assembly.
Pass the splash guard
(37),
and bearing
(37),
over
the end of the shaft. Press the bearing onto the
shaft.
Flt key and hub and fit the retaining plate (VLC
tool) over the wheel studs, securing It by the nuts.
Place the whole assembly In a vice, flt the nut and
tighten with a torque spanner to 180 lbs. ft.
(25
kg.m.).
It can be checked that compression has been
obtained by attempting to rotate the Inner splash
guard which Is Interposed between the sleeve and
the bearing Inner race.
Fit splii pin. (Later cars have self-locking nuts
fitted.)
The assembly may now be refitted to the axle casing
(see "Axle-shaft-To refit").
Note:
As the Inner track of the hub bearing Is an Inter­
ference flt on the axle shaft It Is essential that
bearings of the correct type are used.
Bearing sleeves are not supplied separately.
DIFFERENTIAL UNIT-To remove and refit
{�ig.
3)
Drain oil from axle case.
Remove both axle driving shafts as previously
described.
Disconnect propeller shaft from rear axle driven
coupling.
Remove nuts (8) and washers (7), securing differen­
tial housing to axle case.
Lift out assembly.
When replacing the assembly the operations are a
reversal of the above.
The joint faces must be clean and free from burrs.
Use a new joint and coat both faces with a jointing
compound.
Important. Bleed brakes on completing re-assem­
bly of rear axle unit.
REAR AXLE BREATHER
ALPINE.
The breather Is a set-screw with a Ir"
(2·38 mm.) diameter hole drilled through It,
mounted on top In the centre of the casing.
RAPIER. The breather hole Is -h" {2·38 mm.) In
diameter and Is drilled directly on top of the
right-hand side of the sleeve of the axle casing
1-4·2" (360·1 mm.) from the centre of the banjo
casing.
The breather hole should be kept clear at all times.
DIFFERENTIAL UNIT-To dismantle and
reassemble (Fig. 3)
Remove assembly from axle.
Remove caps over bearings supporting differential
assembly.
