3 Installing the Air Locker

3.5 Preload Shim Measurement

In order to preload the tapered roller bearings in your Air Locker,

measurements need to be taken so that a value can be calculated for

the total shim thickness ‘E’ in Figure 6.

Figure 6.

c Hold the bearing cups in place over their matching bearing cones.

c Insert and hold the Air Locker into the differential housing.

c Insert the shim pack determined earlier as ‘D’ between the bearing

cup and the differential housing (right hand side as shown in Fig.4.)

c Push (or lightly pry) the Air Locker hard across to the right-hand

side, and measure the gap (also called the ‘end float’) between the

bearing cup and the housing with a feeler gauge (See Fig 7.).

c Record this measurement.

c Consult your vehicle manufacturer’s service manual to determine

the carrier bearing preload amount specified for your vehicle.

NOTE : If your service manual specifies preload in terms of a

torque value measured off the drive pinion flange,

then assume a preload amount of 0.25mm [0.01”] for

the following calculations. Once you have assembled

the housing to check the final backlash (Refer to

Section 3.12 Checking the Backlash) you should verify

that your preload is correct using a torque wrench and

your service manual’s table of values.
