(tensioning rewind spring) Prying out worn starter rope guide bush Flaring the new rope bush
- Grip the rope close to the rotor and use i
t
to turn the rope rotor three full turns
clockwise.
- Hold the rope rotor steady.
- Pull out rope with starter grip and
straighten it out.
- Hold the starter grip firmly to keep the rope
tensioned.
- Let go of the rope rotor and slowly release
the starter grip.
Note: The rewind spring is correct-
ly tensioned when the starter grip
sits firmly in the rope guide bush
without drooping to one side. If this
is not the case, tension the spring by
one additional turn.
When the starter rope is fully extended it
must still be possible to rotate the rope rotor
at least another half turn before maximum
spring tension is reached. If this is not the
case, pull the rope out, hold the rope rotor
steady and take off one turn of the rope.
Do not overtension the rewind spring as
this will cause it to break.
- Tighten down the hexagon nut until the
bush is firmly seated.
Note: The installing tool flares the lower
end of the rope bush.
- Refit the starter rope and the starter
grip.
- Tension the rewind spring - see 6.5.
- Fit the fan housing.
The wear on the guide bush is accelerated
by the starter rope being pulled sideways.
The wall of the guide bush eventually
wears through, becomes loose and has to
be replaced.
- Remove the fan housing.
- Relieve tension on rewind spring,
see 6.2, and remove the starter grip.
- Use a suitable tool to pry the old bush
out of the fan housing.
To install the new rope bush:
- Place the new bush in its seat in the fan
housing.
- Insert the screw spindle of the installing
tool through the bush from inside the
housing.
- Fit the thrust sleeve, tapered end first,
and the hexagon nut.
