1. GENERAL

1.1 DESCRIPTION

Differential
The differential has a hypoid bevel gear.

A single reduction is applied.

The bevel gear-to-pinion backlash is achieved

using adjusting nuts.

The pinion housing can be removed using jacking

screws.

The pinion bearing is adjusted using shims which

are placed between the inner bearing races.

Differential lock
The differential is equipped with a variable

differential lock.

The right side of the satellite-gear housing flange

is fitted with spline toothing. The left side of the

selector sleeve is equipped with similar toothing.

The selector sleeve is fitted with splines, similar

to the splines in the axle shaft.

The outside of the selector sleeve is fitted with a

groove, in which a fork fits which is attached to

the engaging cylinder.

If the engaging cylinder is pressurised using a

pneumatic switch, the toothing of the selector

sleeve will mesh with the toothing of the satellite-

gear housing.

If the engaging cylinder is vented via the

pneumatic switch, the spring will ensure that the

lock is deactivated.

Wheel hub unit
The wheel hub, wheel bearings in compact

version and hub oil seal form a unit, also called

the wheel hub unit (3).

The thrust washer (2) installed between the hub

nut (1) and wheel bearing, is fitted with two

straight surfaces on the inside to prevent the

washer from turning. This is to prevent the hub

nut (1) from loosening in case of wheel bearing

problems. The hub nut (1) is of the self-locking

type. The nut is locked by bending the lips on the

hub nut outward.

The wheel bearings of the wheel hub unit are

greased and are maintenance free.

The correct wheel bearing pre-load is achieved

by installing the hub nut as specified.
