3 Installing the Air Locker
16
c Assemble the new bearing cup and master shim (supplied with your
Air Locker kit) onto the right-hand side of the Air Locker (as shown
in Fig.12.) and measure the total distance ‘B’.
NOTE : The shim pack ‘C’ should not be installed at this time.
Figure 12.
c Record this measurement as ‘B’.
The thickness of the shim pack ‘C’ should make the distance ‘B’ on the
Air Locker closely match the distances ‘A’ on the original differential
(within 0.1mm [0.004”] ).
c Use the following calculation to find the desired thickness of ‘C’:
A – B = C (Replacement Shim Pac k)
HINT : If your calculations are correct then the following
equation will also be true:
A – B – C = ZERO
