Insert spider in flange yoke. Then using a
soft-nosed
drift
about
&"
smaller in dia-
meter
than
the hole in the yoke, tap the
bearing into position. It is essential that
bearing races
are
a light drive fit
in
the yoke
holes. Repeat this operation for the other
three
bearmgs.
Refit snap
rings
with a suitable pair of
circlip pliers, ensuring that rings engage
properly
with
their
respective grooves. If
joint appears to bind after assembly, tap
lightly with a soft hammer, thus relieving
any pressure of the bearings on the ends of
the trunnions.
WHEN REPLACING SLIDING JOINT
ON
SHAFT
BE
SURE
THAT SLIDING
AND FIXED YOKES
ARE IN THE
SAME
PLANE
AND ARROW
MARK-
INGS COINCIDE.
A
single universal
joint does not transmit uniform motion
when the driving and driven shafts are out
of line, but when two joints are used as
in
the case of a propeller shaft, and are set
in
correct relation the one to the other, the
errors of one are corrected by the dis-
crepancies of the other, and uniform
motion is then transmitted. Hence the
importance
of re-engaging the splines cor-
reccly when they have been taken apart.
