3 Installing the Air Locker

F Assemble the new bearing cup onto the right-hand side of the Air
Locker (as shown in Fig. 7.) and measure the total distance ‘C’.
NOTE : The shim pack ‘B’ will be determined and added later.
Figure 7.
F Record this measurement as ‘C’.
The thickness of the shim pack ‘B’ should make the distance ‘C’ on the
Air Locker closely match the distance ‘A’ on the existing differential
(within 0.1mm [0.004”] ).
F Use the following calculation to find the desired thickness of ‘B’:
A –– C = B (Replacement Shim Pac k)
HINT : If your calculations are correct then the following
equation will also be true:
A –– B –– C = ZERO
