4.1 Installing the Carrier Bearings
c With the Air Locker well supported in an arbor press, apply a thin
film of high pressure grease to the ring gear side bearing journal,
and assemble the newly established shim pack onto the bearing
journal.
c Press the tapered roller bearing cone onto the bearing journal of
the differential carrier until the bearing seats firmly against the shim
pack.
NOTE : Never re-use any bearings which are damaged or
worn.
c Invert the Air Locker and apply a thin film of high pressure grease
to the seal housing side bearing journal.
c Press the bearing cone which was supplied with the Air Locker kit
onto the bearing journal.
c Press the bearing cup which was supplied into the seal housing
with the taper facing outwards.
4.2 Mounting the Ring Gear
c Cut the cable ties off of the Air Locker flange.
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 of the ring gear and the Air Locker
flange.
NOTE : Rubbing the ring gear mounting face with a flat oil
stone 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 an
oven or in hot water 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.
