Grease nippre universarjoint.
The driven
portion
of
the centre
joint
is provided
with serrations
which
engage similar serrations within
the
propeller
shaft
to
permit
the necessary degree
of
telescoping
movement.
This sliding
joint
is
also lubricated by means
of a
grease-gun
lubricator, shown at (2,
Fig.
23). Every
ro,ooo miles, as directed
on
page
32,
the correct
grease
should be injected
by means of the
grease-gun into all
the
four
lubricators.
Rear
Axle.
The rear axle is
of the
semi-floating type.
The
final
drive
is
by offset
hypoid bevel
gears,
which
possess
the
advantages
of being silent in
running,
and,
owing to the offset
disposition
of
the
pinion,
of enabling a lower
body position
to
be
obtained without
decreasing
the
ground
clearance.
It
i9
important that no other
oil
than that
recontmended
shou,ld be
used
in the rear
axle.
(See
page
28.)
Every
5,ooo
miles, as directed
on
page
3r,
the level
of
the oil
should
be inspected,
and
topped-up if necessary.
Every
za,ooo miles,
as directed
on
page
34,
the casing
must
be
drained,
and refilled
with
fresh oil
to the correct
level.
The drain plug
(2,
Fig.
24)
should be
removed,
with the special
spanner provided,
preferably
when
the casing is warm; and
all
the
oil
allowed
to
drain out.
