IMPELLER REMOVAL
1. Disconnect spark plug wire.
2. Secure the unit to keep it from moving.
3. Remove the nozzle (item 7) from the housing, then remove the plate it was attached to (item 30).
4. Walk the belt (item 22) off of the lower pulley (item 23) and then slide it off of the impeller groove. If you cannot walk
it off of the bottom pulley loosen the bearings (item 24) on the underside this will allow a little more play in the pulley.
5. Slide belt out of belt groove in impeller hub drive pulley.
6. Remove impeller bolt and lock washer.
7. If impeller slides off freely, proceed to (step 12). (Do not drop impeller).
8. If impeller does not slide off crankshaft, place two crowbars between impeller and housing on opposite sides. Pry
impeller away from engine until it loosens. Using a penetrating oil can help loosen a stuck impeller.
9. Slide impeller off of crank shaft and remove impeller from housing.
10. Reinstall new impeller, new impeller bolt and lock washer in reverse order of removal. (See the parts drawing on
pages 10-13 for parts break-down and parts list on page 11 for proper impeller bolt torque specifications.)
11. When impeller is installed, slide the belt back into the groove on the hub and walk it back onto the bottom pulley.
Retighten the bearings if they were loosened.
12. Reattach nozzle plate and nozzle in reverse order of removal.
13. Reconnect spark plug wire.
14. Check for proper operation.
Grease: Wheels, Casters, and Shaft Bearings.
Tire air pressure: Check at regular intervals & maintain: Rear SP 13" tires at 20 psi. (137.9 kPa).
DRIVE
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.
8. Check for proper operation.
