REAR
AXLE
I.
GENERAL
A
new rear axle assembly, Part No. 302177,
bearing the Serial No. 13511, was jntro-
duced at Commission No. 13046 and fitted
on all subsequent cars.
The major differences incorporated in the
new axle include new half shaft and hub
assemblies, a thrust button mounted on the
differential cross-pin and adjustable taper
roller hub bearings, as shown in Fig. 1.
The sectioned insert views indicate the axle
arrangement for cars prior to this change.

LUBRICATION OF
REAR
HUB
BEARINGS
The rear hub bearings are each lubricated
by a grease nipple located behind the brake
backing plate and facing downwards, as
shown in Fig. 2. The nipples should
receive a small but regular supply of grease,
as specified on pages
9-12
(Section
"
A
").
Six strokes of the hand grease
gun
every
6,000 miles (10,000
km.)
will normally be
sufficient, as it is inadvisable to overload
with grease.
