4 Installing the Air Locker
12
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 both bearing journals.
c Press one of the tapered roller bearing cones onto one of the
bearing journals of the Air Locker until the bearing seats firmly
against the bearing journal shoulder.
c Invert the Air Locker and press the second bearing cone onto the
opposite bearing journal until the bearing seats firmly against the
bearing journal shoulder.
NOTE : Never re-use any bearings which are damaged or
worn.
4.2 Mounting the Ring Gear
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.
c Dry the ring gear with compressed air (if wet), paying particular
attention to the threaded holes.
c Install the ring gear onto the Air Locker by aligning the holes in the
flange with the tapped holes in the ring gear, then gently tapping it
around in a circle with a plastic or copper hammer.
