DIFFERENTIAL BEARINGS ADJUSTMENT
There are two methods by which adiustments can be made to the differential bearings.
The f i n t method uses a dial gauge to measure the thickness of the adjusting washers,
which i s directly related to the bearing stress.
Thesecond method measures the torque
required to rotate the differential usinga spring balance.

Position the differential and bearings.
(a)
Place the differential together with bearings i n the end o f the gearbox
casing.
