4.6 Final Air Locker Assembly
c With the seal housing removed 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 seal housing 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
downward twisting motion. This will allow the O-rings to gently
engage.
c Assemble the shim pack over the seal housing tube and onto the
seal housing spigot (Figure 9.).
c Point the seal housing tube straight out of the housing, hold the
shims, seal housing 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.
NOTE : When installing the bearing cap be careful not to
damage the shims.
c Check to see if the bearing cap on the seal housing side fits over
the tube without fouling and fits properly in place.
NOTE : Do not forget to check the bearing caps are turned the
correct way around.
c Install all bearing cap bolts and torque to manufacturer’s specs.
