10. Place a new gasket on the
brake carrier plate and then slide
the axle shaft into the
housin~.
Start the axle splines into the
side gear, and push the shaft in
until the bearing bottoms in the
housing.
11. Install the bearing retainer
and the nuts that secure it. Torque
the nuts to 30-35 foot-pounds.
12. Install the brake drum and
the drum retain
ing· nuts.
Adjust
the brakes.
13. Install the wheel and tyre
on the
drum.

FROM AXLE HOUSING
.
(Brake drums removed)
Remove the clamping plate and pull the
shaft from the housing.
The UNIT
TYPE BEARING cup will normally
stay in place in the axle housing when the
axle shaft is
removed.
The bearing cup
can be removed from the axle housing
by using a standard slide -
hammer
type puller as in Fig. 14.

Installation
The UNIT TYPE BEARING cone
assembly should not be pulled
from the axle shaft unless
:
1. The seal is to be replaced.
2. The clamping plate has to be
replaced due to damage or
distortion.
3. The bearing is to be replaced.
The bearing cone assembly should
have all parts completely covered
with rear axle oil prior to re-
installation into the axle housing.
Also apply oil to the seal seat on
the shaft.
Installation of Axle Shaft in Axle
Housing
1. Install the bearing cup in the
axle housing, ensure that the
cup back face is seated against
GROUP
4-REAR AXLE
the backing shoulder in the
housing.
2. Care should be taken when
installing the axle shaft to avoid
seal
damage.
Start the splined
end of the shaft into the
differential and start the cup
rib ring and seal into the
housing.
3. Line up the clamping plate to
the clamping plate bolts and
push the axle into the housing
as far as possible.
4. Start the nuts onto the clamp-
ing plate bolts and tighten to
finger tight only. Then tighten
all nuts to approximately 15 ft.
pounds torque. The nuts
should be tightened in such a
manner to assure that the seal
and cup rib ring are drawn
evenly against the cup in the
housing. The final tightening
of the nuts should be done
with a torque wrench to 30-35
ft. pounds.

AND INSTALL
To
Remove
I. Retaining collar removal. The
retaining collar can be easily
removed by drilling a
!"
hole
in the outside diameter of the
collar to a depth approxi-
mately three-quarter the thick-
ness of the collar. Do not drill
all the way through the collar
as the drill could damage the
axle shaft. After drilling the
retaining collar, position a
chisel across the drilled hole
and strike sharply to break
the collar.
NOTE -
Backing collars are
not reuseable after having once
been installed and must be
scrapped after removal even
if some removal method is
used which does not cause
obvious damage to the collar.
2. Slide the clamping plate and
seal toward the axle flange.
3. Position the guillotine type puller
jaws (tool no. XYTC 1225)
behind the bearing cone face,
ensure that the jaws do not
touch the seal seat.
Install the axle with guillotine
jaws in position into the guillo-
tine jaw retainer tool - Remove
the
bearing.
NOTE -
Do not heat or cut
the bearing assembly as damage
to the axle shaft will result.

Removal
new seals and retaining collars
must be
used.
2. Check the clamping plate for
damage or distortion with a
straight edge. If the plate is
distorted, replace
it.
3. Clean the axle shaft, ensure
that there are no burrs or nicks
on the bearing seat, cone back-
ing shoulder and chamfer lead-
ing to the seal seat. Sharp
edges or nicks on the chamfer
leading to the seal will damage
the seal lips duririg installation
of the seal on the shaft. To
avoid damage to the wheel
studs, place the axle shaft
flange face on a
support.
4. Install the clamping plate on
the axle
shaft,
ensure that it is
positioned with the clamping
face of the plate toward the
bearing.
5. Apply grease to the cavity
between the seal lips and care-
fully slide seal into position
on the seal seat. When installed
the outer face of the seal must
be toward the axle flange. Do
not push the seal onto the
rough surfaced portion of the
seal seat.
6. The new UNIT TYPE BEAR-
ING must be lubricated prior
to
installation.
Do not wash a new bearing
prior to installation. The new
UNIT TYPE BEARING has a
protective grease which pro-
vides initial lubrication until
the
re.
a r axle lubricating oil
reaches the bearing.
If the new bearing has to be
washed for any
reason,
it must
then be completely lubricated
with rear axle oil prior to
installation.
7. Place the lubricated UNIT
TYPE BEARING on the axle
shaft ensuring the cup rib
ring is facing toward the axle
flange.
