Turning
Force
of
Spiral Bevel Pinion Shaft
1.
Install the spiral bevel pinion shaft assembly
to
the
front
axle
case.
2.
Wind a string around the spiral bevel pinion shaft and attach
spring balance
to
the
tip
ofthe
string.
3.
Slowly pull the spring balance in a direction
at
right
angle
to
the spiral bevel pinion shaft
to
measure
the
turning
force.
4.
If
the turning force
is
not
within
the factory specifications,
adjust
with
the lock nut.

NOTE
..
The
turning
torque
is
figured
by
multiplying
the
radius
(distance from the center
of
the spiral bevel pinion shaft
to
a
point on the circumference from which the string
is
pulled)
by the reading on the spring balance.
•
After
turning force adjustment,
be
sure
to
stake
the
lock nut.
Backlash between Spiral Bevel Pinion Shaft and Spiral Bevel
Gear
1.
Set
a dial gauge (lever type)
with
its finger on
the
spline
of
spiral bevel pinion shaft.
2.
Measure the backlash
by
moving the spiral bevel pinion shaft
by
hand lightly.
3.
If
the
backlash
is
not
within
the
factory
specifications,
change the adjusting collars
(3),
(4).
For
example change
the
adjusting collar
(4)
to
0.1
mm
(0.004 in.) smaller size, and
change the adjusting collar
(3)
to
0.1
mm
(0.004 in.) larger
size.

backlash
properly
