3 Installing the Air Locker
13
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.
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”] ).
Use the following calculation to find the desired thickness of ‘
B
’:
A – C = B

k)
HINT :
If your calculations are correct then the following
equation will also be true:
A – B – C =
ZERO
