GENERAL DESCRIPTION
The
propeller
shaft and universal joints are of
the
Hardy Spicer type with needle roller bearings.
AsIngleshaft connects
the
rear
axle and
the
gearbox.
To accommodate fore and aft movement of
the
axle,
the
shaft Is provided with a spllned sliding Joint at
the
front end. Each universal joint consists of a
centre
splder, four needle

ATTENTION
TO
UNIVERSAL JOINTS
The
propeller
shaft has a lubricator fitted
to
the
front and
rear
spiders which should be given
three
or
four
strokes with
the
grease gun every 1,000 miles
(1600 km.),
The
correct
lubrlcantIs
grease
to
Ref. D
(page P.2).
If a large amount of grease exudes from
the
oil seal
the
joint should be dismantled and new oil seals fitted.
A lubricator Is also provlded on
the
sleeve yoke for
the
lubrication of
the
splines of
the
sliding Joint.
Lubrication In service is with grease to Ref. D (page
P.2)
every
1.000 mlles (1600 km.). After dismantling,
and before reassembling.
the
Inside splines of
the
sleeve yoke should be smeared liberally with grease.
There
are,
therefore,
three
lubricators In
allan
the
propeller
shaft. one on each universal joint and one
on
the

TESTING FOR WEAR
(In Position)
Wear
on
the
thrust
faces Is ascertained by testing
the
lift in
the
Joint,
either
by hand
or
wlth
the
aid
of a length of wood. SUitably pivoted.
Any circumferential movement of
the
shaft relative
to
the
flange yokes indicates
wear
in
the
needle roller
bearings
or
In
the
splined shaft.
