(Commercial Chassis)
consisting of a flat plate, as shown in inset, Fig.
7-14, may be made up and used with Slide Ham-
mer, J-2619, to remove axle shaft seal.
Install plate on slide hammer shaft, using a flat
washer and nut on threaded end of shaft to hold
plate in position. Slide shaft with plate through
seal and pull shaft outward to position plate
against inside face of seal, Fig. 7-14. Be sure
plate is not behind shoulder in housing, as this
would bend plate. Drive outward with slide ham-
mer to remove seal.
Before installing a new seal, wipe counterbore
into which seal is pressed and carefully remove
any nicks or burrs. Sealing surface on axle shaft
should be polished, using 400 grit "wet" paper
and kerosene to insure a smooth surface and to
prevent wear on seal. Clean shaft after sanding.
Outside diameter of oil seal should be coated
with non-hardening gasket sealer before in-
stallation.
Oil seal must be pressed squarely into its bore
and against its seat. Use flat plate previously
used for removing seal. Tap gently on plate, being
careful not to distort seal casing.
9. Differential Carrier Removal
and Installation
NOTE: Any service on the differential
carrier assembly, standard or controlled type,
except pinion oil seal, and flange or yoke r e -
placement, Notes 2 and 3, should be handled by
replacement of the complete assembly. No dis-
assembly or adjustment of this unit should be
attempted in the field, because special equip-
ment is needed for selection of mating parts and
setting side bearing pre-load.
a. Removal
1. Disconnect rear universal joint at pinion
flange or yoke.
2. Remove axle shafts, as described in Notes 6
and 7.
3. Remove nuts and washers that hold carrier
to axle housing, and remove entire assembly with
gasket. Provide container for collecting oil as
differential carrier is removed from axle housing.
NOTE: Whenever a carrier is removed be-
cause of scored gears, worn bearings, or any
failure that might cause dirt or metal chips, r e -
move axle housing from car for thorough clean-
ing before new carrier is installed. Also check
axle shaft assemblies and clean as necessary.
b. Installation
NOTE: On cars equipped with a Controlled
Differential, check internal splines of differ-
ential side gears and cone clutches to be sure
they are aligned. This check is made by insert-
ing axle shaft splines in each side of differ-
ential until they bottom against differential
pinion shaft (approximately 4 inches).
1. Scrape any old gasket material from housing.
Coat both sides of a new gasket with non-harden-
ing sealer and place gasket on housing.
2. Position differential carrier on axle housing
and install new copper washers and nuts on hous-
ing studs. Tighten nuts to 37 foot-pounds.
3. Install axle shafts as described in Notes 6
and 7.
4. Fill rear axle with lubricant as described in
Section 2, Note 4. If a replacement differential is
installed, the special differential lubricant shipped
with the new differential must be used.
5. Connect rear universal joint at pinion flange
or yoke and tighten bolts or nuts to specified
torque, Notes 2b and 3b.
NOTE: In case of lubricant leakage between
differential carrier and axle housing, make sure
that nuts are tightened to 37 foot-pounds. If
this does not stop leak, install an extra gasket,
using a non-hardening sealer.
10. Propeller Shaft Assembly Removal
and Installation
a. Removal
1. Raise car on hoist.
2. Remove two center bearing support-to-frame
bolts. The nuts for these bolts are tack-welded to
the center bearing support and bracket assembly,
and remain fastened to the bracket.
3. Remove four attaching screws and lock
washers at rear axle pinion flange on 60 and 62
series c a r s . Remove " U " bolts and locks on
