FAN REMOVAL AND INSTALLATION
Remove spark plug wire from spark plug.
Remove nozzle assembly.
Remove front plate assembly.
Remove the bolt that secures the fan to the engine
crankshaft.
The fan has a 3/4-16 nut welded on fan hub. Turn a 3/4-
16 x 5" long grade 5 (or better) bolt into the nut to jack or
push the fan off the engine. (Schiller Grounds Care, Inc.
P/N 910515 Bolt-Jack Fan is recommended.)
Replace damaged or worn fan with a new one. If during
fan removal the key (#64164-13) was removed from the
keyway, reinstall it by applying a few drops of the Loctite
380 instant adhesive (“Black Max” P/N 38050) on the key,
and load the key in the keyway of the shaft. (Cure time is
approx. 1 min.)
Use a new bolt (#64123-307) (add Loctite 263 to
new bolt) and washer (#4168981) and complete fan
installation. Ensure a secure fit upon re-assembling.
