Differential Carrier Assembly
Installation of Forward Axle Housing Cover
and Output Shaft Bearing Parts
Note: Forward axle should be assembled to the axle housing
before proceeding with the following procedure.
1.
If removed, install housing cover and fasten with
nuts, capscrews and lock washers. Tighten to proper
torque specifications (see Torque Chart on page
107).
Note: Use silicone rubber gasket compound on axle housing
mating surface as shown in illustration. Completely re-
move all old gasket material prior to applying new mate-
rial. Compound will set in 20 minutes. Install axle
housing cover and output shaft assembly before com-
pound sets or reapply.
2.
Install output shaft rear bearing. Tap the outer race
(with a sleeve or brass drift) until it is seated firmly in
the machined pocket of the cover. Secure with snap
ring.
3.
Lubricate and install the rear bearing sleeve on the
output shaft. Make certain it fits snugly against the
shoulder at the forward edge of the shaft splines.
4.
Install the output shaft seal in the axle housing cover.
Note: Some axles require the use of a rear bearing retaining
washer. Install the washer over the splines of the output
shaft flush against the output shaft bearing.
5.
Install output yoke and self-locking nut. Tighten to
specified torque (see Torque Chart on page 107).
Reference Yoke Installation Section page 92.
6.
Install axle shafts and axle stud nuts (If used, also in-
stall lock washers and taper dowels).
The differential lock 461/521/581 models use axle shafts
with different spline length (4" or 11"). Axle shafts may also
be location specific with various wheel equipment. Do not
misplace axle shafts from their intended location.
7.
Connect main and inter-axle driveline. Ensure drive-
lines are properly phased. Lubricate U-joints.
8.
Add axle lubricant. See Lube Fill Capactities on page
104 for correct amount.
Note: Oil fill plug removed from D461/462/463 Differential
Carriers. The oil fill plug hole located in the differential
carrier was removed. Lube capacity is not affected, cus-
tomers to fill axle with lube through rear cover fill hole or
through the breather hole in housing. February 1, 2000.
9.
Connect air lines to differential.
When axle has been disassembled or housing, axle shafts or
wheel equipment replaced, check axle assembly for proper
differential action before operating vehicle. Wheels must ro-
tate freely and independently.
Road test vehicle to bring axle lubricant up to temperature. Re-
check joints, drain and fill plugs for leakage. Re-tighten as nec-
essary.
WARNING
1 - Apply silicone gasket in this pattern
2 - Stud locations (varies by model)
