3 Installing the Air Locker

c Select shims from the shim kit supplied with your Air Locker to

make the thickness ‘C’ as determined above.

c Place this shim pack between the master shim and the bearing cup.

c Re-measure the new distance ‘B’ from the Air Locker (now

including the shim pack ‘C’) to make sure that it matches the

distance ‘A’ on the original differential.

NOTE : NEVER machine the Air Locker.

3.4 Mounting the Ring Gear

IMPORTANT:

Newer OEM Dana 35 ring and pinion sets use 7/16” bolts.

The flange holes of the Air Locker must be reamed from

Ø3/8” to Ø7/16” to suit.

c Apply a thin film of high pressure grease to the ring gear shoulder

of the Air Locker to prevent seizing.

c Thoroughly clean any thread locking compound or other foreign

matter from the holes of the ring gear, the threads of the ring gear

bolts, and the mating surfaces between the ring gear and the Air

Locker flange.

HINT : Stoning the ring gear mounting face before

installation will remove any high spots around the

threads.

c Heat the ring gear to between 80 and 100°C [175 - 212°F] in hot

water or in an oven to slightly expand the gear and facilitate

assembly.

NOTE : NEVER HEAT GEARS WITH A FLAME! This could

damage the hardened surface of the gear and result

in premature wear or failure.

c Dry the gear and bolt holes with compressed air (if wet).

c Install the ring gear onto the Air Locker by aligning the bolt holes

and then gently tapping it around in a circle with a soft mallet.

Avoid using the bolts to pull down the ring gear as this puts excess

strain on the bolts and the differential flange.

c Apply a thread locking compound to the thread of each ring gear

bolt before inserting it. Do not apply threading compound directly

into the threaded hole as this could prevent the bolt from reaching

its full depth.

c Tighten the ring gear bolts in a star pattern with a torque wrench

according to your vehicle manufacturer’s specified torque.
