Fig. 4 B - 4 -8 -1 /2 " and 8 - 7 /8 " Ring Gear Axle Cross-Section Typical
depth, while the outer pack controls pinion hearing
preload.
Dana 9 - 3 / 4 " Ring Gear Axle
T h e D a n a axle shown in figure 4B-7 is sim ilar to the
u n it shown in 4B-6; however, the differential side
bearing shim s are located between the case and the side
bearings.
C h evro let 1 2 - 1 / 4 " Ring Gear Axle
( 1 1 ,0 0 0 Pound Capacity)
T h e 11,000 lb. capacity, single-speed hypoid axle,
illustrated in figure 4B-8, has a straddle m ounted drive
pinion which is supported at the r e a r by a straight roller
bearing. The pinion front bearing consists o f a double
row ball bearing.
The differential is a conventional four-pinion type.
Thrust washers are used between the side gears and case
and also between differential pinions and the differential
case.
A thrust pad m ounted on the end o f an adjusting
screw threaded into the carrier housing limits deflection
o f the ring gear u n d e r high torque conditions.
Involute splines are incorporated in the axle shaft
flange and in the wheel hubs. This design provides for
the driving torque to be transm itted from the axle shaft
to the hub through the m ating splines.
