Measure
the backlash
of
the secondary bevel gear using
the
dial
gauge,
as
shown. Take backlash readings
at
several
places
while
turning
the drive bevel gear in each
direction.
If the
backlash
is
not
within
specification,
the shim thickness must
be
changed
and
the backlash checked
until
it is
within
specifica-
tion.
Refer
to the
chart
at the
