gear backlash
Split
the crankcase.
Leaving
the
drive shaft
and
crankshaft in
place, measure the
backlash
between
the
clutch housing
gear
and the
primary gear.
To
measure
the
backlash,
set
a dial gauge against the teeth
of one
gear,
and
move the
gear
back and
forth while holding
the other gear
steady.
The
difference between
the
highest
and the
lowest
gauge reading
is
the amount
of
hacklash. Replace both the clutch housing
and the
primary
gear
whenever
the
amount
of
backlash
exceeds
the service
limit.
