REAR AXLE
HYPOID BEVEL DRIVE
GENERAL DESCRIPTION
A rear axle of the semi-floating type with detachable
taper mounted hubs, incorporating a hypoid bevel
drive is fitted to Alpine and some Rapier cars. In
design it is essentially straight forward, but as the
position of the pinion relative to the crown wheel
requires accurate adjustment involving the use of
special tools, it should remain undisturbed as far as
possible.
Crown wheel and bevel pinion adjustment is
provided by disposition of shims adjacent to the
taper roller bearings carrying the differential
housing and the bevel pinion shaft, described in
detail In this section.
The complete differential assembly is detachable
from the axle casing after removal of the axle shafts,
when major attention to the unit is required. The
axle shafts are fully machined and supported at their
outer ends on ball bearings.
BEVEL PINION HOUSING OIL SEAL
(Figs. I and 3)
In the bevel pinion housing an oil seal (27), ls fitted
just to
. the rear of the propeller shaft driven
coupling (32). Whenever a replacement oil seal Is
fitted, the outside of the cage should be coated
with a liquid jointing compound before the seal is
pressed into position. These seals operate most
effectively in one direction, and thus they should
be fitted with the lip and spring facing the rear axle.
They are easily removed and replacements can be
pressed Into position.
