4.8 Air Locker Final Assembly
c Remove the seal housing, shim pack, and master shim, and clean
all parts of the differential assembly. It is very important to make
sure the seal housing grooves are free from any contaminants (eg:
water, dirt, metal fillings, etc.)
c Lubricate the O-rings with oil (prior to assembly), then stretch them
over the bearing journal and release them into the grooves.
NOTE : Do not roll the O-rings onto the journal as this will
damage them.
c Place the bearing cups onto their respective bearing cones.
c Install the seal housing over the O-rings by gently applying a
twisting motion. This will allow the O-rings to gently engage.
c Assemble the shim pack and master shim.
c Point the seal housing tube straight out of the housing, hold the
shims and tapered roller bearing cups in place, and insert and hold
the Air Locker into the differential housing.
c Install the bearing cap on the ring gear side.
c Check to see if the bearing cap on the seal housing side fits over
the tube without fouling.
c Install all bearing cap bolts and torque to manufacturer’s specs.
NOTE : Assembly space in some Land Rover differentials has
been found to vary slightly. Using an automotive
feeler gauge, check that some clearance exists
between the bearing cap and the Air Locker
(Figure 15.). Rotate the differential one full turn while
checking. If any part of the Air Locker contacts the
bearing cap then the cap should be removed and any
contact points should be filed or ground until some
assembly clearance exists.
