3 Bench Measurement

HINT :

If your calculations are correct then the following
equation will also be true:

A + B – C – D =

ZERO

Create a shim pack to match the thickness calculated as ‘D’.

To achieve the desired shim thickness you can:

• Machine down the factory shim thickness.

• Add shims between the factory shim and the bearing cup.

HINT : A selection of shims of this size have been supplied

with your Air Locker kit.

• Purchase new factory shims at the desired thickness.

• Use a universal shim kit available from most drive train

specialists.

• Add small amounts of shim between the bearing cone and the

bearing seat.

NOTE : NEVER machine the Air Locker.
