3.2 Calculation & Selection of Shims
The thickness of the shim pack required for the Air Locker (shown as
‘D’ in Figure 5.) can now be determined by substituting the
measurements taken into the following equation.
A + B – C = D
HINT : If your calculations are correct then the following
equation will also be true:
A + B – C – D = ZERO
To make a shim pack to match the measurement you calculated as ‘D’
you can:
§ Either machine the ring gear side shim, or purchase a new one
of the correct thickness from your Nissan dealer.
§ Add shims between the master shim and the seal housing.
§ Use a universal shim kit available from most drive train
specialists.
NOTE : Never re-use any shims which are damaged or worn.
