Belts are normal replaceable wear items.
Belt Replacement
:
1.
Follow steps 1-9 in the impeller removal section. The impeller will need to be removed to replace the belt
2.
Loosen the set screws on the pulley at the end of the shaft. This will allow the pulley to slide out of the way of the
belt. Walk the old belt off the pulley.
3.
Remove the old belt by feeding it through the housing and replace it with a new one, making sure to walk the belt
around the bottom pulley.
4.
Install the impeller and make sure the belt is in the groove on the hub. Use new hardware to attach the impeller.
DO NOT reuse old impeller bolts.
5. Align the pulley so the belt will be running straight, then tighten the set screws. NOTE: make sure the key in the
lower pulley is still in place and hasn’t fallen out.
6.
Reattach the nozzle plate and nozzle in reverse order of removal.
7.
Reconnect spark plug wire.
