Assembly and Installation
MAINTENANCE MANUAL
A. Apply axle lubricant to the inner bore of the
bearing cage or the outer diameter of the new
oil seal.
CAUTION
HOLD THE SEAL ONLY ON THE OUTER DI-
AMETER. DO NOT TOUCH THE LIPS IN THE
INNER DIAMETER OF THE SEAL. IF YOU
TOUCH THE LIPS ON THE INNER DIAMETER
OF THE SEAL, YOU WILL CONTAMINATE THE
LIPS AND COULD CAUSE A LEAK BETWEEN
THE SHAFT AND THE SEAL.
B. Place the oil seal into the bearing cage so
thattheange is parallel to the top of the
cage.
C. Use a press and driver or at metal plate
to install the oil seal into the bearing cage.
Figure 5.67.
NOTE: If you replace either the bearing
cap or cone, replace both parts in a fully-
matched set from the same manufacturer.
4. On differential assembly that do not use an
oil pump, install the input bearing cage.
A. If removed, install the bearing cone in the
input shaft. Use a press and sleeve to install
the cone in the input shaft until it bottoms on
the shoulder of the shaft. Figure 5.69.
B. Install the O-ring onto the input bearing cage.
C. Place the cage over the input shaft so that
the cap in the cage is against the bearing
cone.
CAUTION
DO NOT APPLY PRESSURE AFTER THE
SEAL FLANGE TOUCHES THE TOP OF THE
CAGE OR YOU WILL DAMAGE THE CAGE.
D. Applypressureuntilthemetalangeofthe
seal is seated to the top of the cage.
E. After the seal is installed, a gap of 0.015-
0.030-inch (0.381-0.762 mm) can exist be-
tween the ange and the cage. The gap is
a normal condition because of the exible
coatingontheangeoftheseal.Useafeeler
gauge to measure the gap between the com-
pleteange-to-cagearea.
• If the gap varies more than 0.010-inch
(0.254 mm) between the highest and low-
est measurement, remove and reseat the
seal. Figure 5.68.
