Installation of Differential Carrier and Gear Set in Housing
CAUTION: Before installing carrier and gear set in axle
housing inspect to make sure no dirt, chips, or other foreign
matters remain to cause damage to gears and bearings.
(52) Install new differential carrier to axle housing gasket,
placing gasket over studs and against housing.
(53) Place differential carrier and gear set assembly in posi-
tion and tighten carrier stud nuts. Use lockwashers under nuts.
(54) Reassemble rear universal joint to companion flange,
using new nut locks. Tighten nuts and bend lock ears over.
(55) Reassemble rear brake shoe assemblies to backing plates.
(56) Assemble brake conduits to backing plates and connect
brake cables to operating levers.
(57) Install axle shaft oil seal assemblies, using oil seal re-
placer J-353-2 (Figure 1319).
(58) Install rear wheel bearing cone and rolls on axle shafts,
using bearing replacer J-358.
(59) Install axle shaft and bearing cone and rolls in housing
and assemble rear wheel bearing outer cup in axle. Pack bearing
with wheel bearing lubricant.
(60) Place wheel bearing adjusting shims (37) between ad-
justing cap (34) and end of housing. Draw up nuts (39) tightly,
using lockwashers under them.
Adjusting Axle Shaft End Play
(61) Clamp dial indicator gauge J-390-X to brake backing plate
so that dial plunger rests against end of axle shaft. Next check end
play, which should be from .004" to .010". This is obtained by
moving the shaft in and out and by taking out or adding shims (37)
between axle housing and bearing adjusting cap.
(62) Install axle shaft keys in keyways and rear wheel hubs and
brake drums on axle shafts.
(63) Place drive shaft nut washers (31) and nuts (29) on axle
shafts and tighten nuts securely, using axle shaft nut wrench J-351,
which has an extra long handle.
(64) Place roller jack under center of axle, raise jack and re-
move the two stand jacks under frame.
(65) Install rear wheels and tires, drawing up wheel bolts tightly.
(66) Lower roller jack, placing car weight on tires and apply
hand brake.
(67) In this position apply extra tightening operation to axle
shaft nuts, then insert cotter pins and spread. Replace hub caps.
(68) Fill axle housing to level of filler plug opening in housing
cover, using high-grade gear lubricant having extreme pressure
characteristics and an S.A.E.- 90 viscosity for winter and S.A.E.-
160 for summer. NOTE: If backing plates have been removed it
will be necessary to readjust brakes.
(69) Road test car to check axle operation.
NOTE : The service procedure applies to Rear Axles of Canadian
built models except for the disassembling of the differential case
and gears assembly. Component parts are not interchangeable
between United States and Canadian Production Rear Axles.
