DESCRIPTION AND OPERATION
C205F AXLE
DESCRIPTION
The C205F ( C orporate 205 mm ring gear F ront)
axle consists of an alumunum center section with an
axle tube extending from one side. The tube is
pressed into the differential housing.
The integral type housing, hypoid gear design has
the centerline of the pinion set below the centerline
of the ring gear.
The axle has a fitting for a vent hose used to
relieve internal pressure caused by vaporization and
internal expansion.
The power is transferred from the axle through
two constant velocity (C/V) drive shafts to the wheel
hubs. The drive shafts are identical and interchange-
able.
The cover provides a means for inspection and ser-
vice without removing the axle from the vehicle.
The C205F axle has the assembly date and gear
ratio listed on a tag. The tag is attached to the hous-
ing cover by a cover bolt.
The differential case is a one-piece design. The dif-
ferential pinion mate shaft is retained with a roll-
pin. Differential bearing preload and ring gear
backlash is adjusted by the use of shims (select thick-

ness). The shims are located between the differential
bearing cups and the axle housing. Pinion bearing
preload is set and maintained by the use of a collaps-
ible spacer.
OPERATION
The axle receives power from the transfer case
through the front propeller shaft. The front propeller
shaft is connected to the pinion gear which rotates
the differential through the gear mesh with the ring
gear bolted to the differential case. The engine power
is transmitted to the axle shafts through the pinion
mate and side gears. The side gears are splined to
the axle shafts.
LUBRICANT
DESCRIPTION
