FRONT AXLE AND FINAL DRIVE

DESCRIPTION AND OPERATION
DESCRIPTION
The welded steel front axle casing houses a separate
spiral bevel type differential unit, which is off-set to the
right of the vehicle centre line. The differential unit
drives the front wheels via the axle shafts and
constant velocity joints which are totally enclosed in
the spherical and swivel housings.
The front wheels are pivoted on tape roller bearings at
the top and bottom of the swivel housing. The wheel
hubs on all axles are supported by two taper bearings
and driven by drive flanges which are splined to the
one piece, stub shaft/constant velocity joint.

DESCRIPTION AND OPERATION
Lubrication
The differential, swivel pin housing and wheel hubs
are indiviudally lubricated and separated by oil seals
(7) and (8), see J6267A, to prevent oil transfer across
the axle when the vehicle is traversing steep inclines.
The wheel bearings are lubricated with grease and the
swivel housing and differential with oil. On later
vehicles, identified by having only a filler plug in the
swivel housing, grease is used to lubricate the
housing assembly,
Ventilation
Ventilation of the differential is through a plastic pipe
(2) which terminates at a high level in the vehicle axle.
The swivel housings ventilate through axle shaft oil
seals (8) into the differential and the hub bearings
vent via the oil seals into the swivel housing.
