3.1 Re-Mounting the Ring Gear
Remove the bolts that hold the ring gear in place.
Using a plastic or copper hammer, tap in a circle around the ring
gear to separate it from the two halves of the original differential
carrier.
Cut the cable ties holding the two halves of the Air Locker together
and separate the case and flange cap.
Apply a thin film of high pressure grease to the outside diameter on
the case of the Air Locker to prevent seizing.
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.
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.
Dry the gear and bolt holes with compressed air (if wet).
Install the ring gear onto the case of the Air Locker by aligning the
bolt holes and then gently tapping it around in a circle with a soft
mallet (Figure 2.).
