THE
PROPELLER SHAFT
GENERAL
DESCRIPTION
The
propeller
shaft and
universal
joints
are
of
the Hardy
Spicer
type
with
needle-roller bearings
in
the universal
joints.
The
rear
end
of
the
shaft
is
■anged and
carries
the
rear
universal
joint
■ange yoke. The
front end of the shaft
is
splined and
engages
a
sleeve
and yoke assembly. In
the
assembled condition
a
dust
cap,
steel washer, and cork
washer seal the end
of the sleeve and
the
sliding joint.
Each universal
joint is
made
up
of
a
spider and
four
gaskets,
retainers,
and
needle bearing
assemblies. Each needle
bearing assembly
is
retained
in its
yoke by
a
circlip.
The yoke ■anges
are
secured
to
the
pinion
and gearbox
■anges respectively with
eight bolts,
spring
washers,
and
Aerotight
or
Nyloc
nuts.

LUBRICATION
A nipple
is
provided
for
lubricating the sliding yoke
at
the
front
end
of the propeller shaft.
On non-sealed
type
propeller shafts lubrication nipples
are
also provided
on
the
front
and
rear
universal
joints. Three
or
four strokes of
a
grease gun are
required when lubricating.

REMOVING AND
REPLACING
THE PROPELLER SHAFT
To
remove
the propeller shaft proceed
as
follows:
1.
Mark the yoke ■anges and the gearbox and
rear
axle
■anges
to
assist in
re■tting them
in
their
original
positions.
This
is
most
important.
2.
Remove the
nuts,
washers, and bolts
securing
the
■anges and
lower
the propeller shaft.
Replacement
is
a
reversal of the removal
sequence,
but
ensure
that the
joint
faces of the ■anges
are
perfectly
smooth and clean and
that
they
are
correctly aligned with
the
gearbox and
rear
axle ■anges.

sleeve
and slide the
sleeve
off the shaft.

4.
Hold the shaft
yoke
in
one
hand and
