8. Install the housing cover, using a new cork
gas-ket and fill the
differential with 3-1/2 pints of the proper hypoid
lubricant.
9. Pour approximately one-half pint of
transmission lubricant
into the front end of the propeller shaft housing to provide initial
lubrication of the propeller shaft bushings.
To Replace the Rear Axle Assembly
Reverse the
operation shown under the removal of
the rear axle. Care should be taken to see that all cotter pins are assembled and securely
bent over. The "U" bolts
holding the springs to the spring seats must be drawn up
securely.
When
connecting the brake cables make sure that all of the play is out of the cables
before connecting and tightening check nuts at idler
lever.
After
replacement of the rear axle it will be necessary to bleed the brake lines at ALL
FOUR WHEELS, as described in
the "Brake Section" of this Manual.
REAR
AXLE ASSEMBLY 1/2 AND
ALL 3/4-TON TRUCKS
The rear
axles used on the 1/2, and all 3/4-ton truck models are the same hypoid type as the
passenger car but their
construction is much heavier. The lubrication of the front pinion
(thrust) bearing is
accomplished by an oil passage drilled in the differential carrier for oil flow to
this bearing. An oil retainer
is mounted in the carrier ahead of the pinion rear bearing to retard the
return of the oil to the differential, thereby maintaining a bath
of oil for the front pinion
bearing.
REPAIR OPERATIONS
The repair
operations for these rear axles are the same as those on the passenger car with
the following
exceptions:
Pinion Assembly—1/2-Ton Model
When assembling the pinion and
shaft assembly. first install the
roller bearing and lock it in place with the lock ring. Then thread the pinion
front bearing oil retainer over
the shaft with the bevel of
the large diameter of the retainer toward the pinion. Coat the
beveled surface of the pinion bearing lock sleeve with rear axle lubricant
and install it with the bevel
side toward the pinion, then assemble the front pinion (thrust) bearing
retaining nut. All other pinion and propeller shaft
operations are the same as those
for the passenger car rear axle.
