SERIAL NUMBER BELOW 310000000
NOTE: ProForce blowers with a serial number below
310000000 use two (2) nuts to secure rotor assembly to
rotor shaft (Fig. 4). Blowers with serial numbers above
310000000 use one (1) nut (Fig. 5).
Removal (Fig. 4)
1. Position machine on a firm, level surface. Make sure
engine is stopped and remove key from the ignition
switch. Chock wheels to prevent machine from moving.
2. To prevent unexpected machine operation, discon-
nect the negative battery cable from the battery terminal
(see Battery Service in the Service and Repairs section
of Chapter 4 -- Electrical System). Position discon-
nected negative cable away from the negative battery
terminal.
3. Remove top grill to allow access to blower assembly
(see Guards Removal in the Service and Repairs sec-
tion of Chapter 6 -- Chassis).
4. Remove blower drive shaft from machine (see Blow-
er Drive Shaft Removal in this section).
5. Remove retaining r ing (item 2), wave washer(s)
(item 3) and front cap (item 4) from shaft.
NOTE: When loosening nuts that secure rotor assem-
bly to r otor shaft, use a 1 1/4” wrench in flats on shaft to
prevent the shaft from turning.
IMPORTANT: The nuts used to secure the rotor as-
sembly to the rotor shaft have left hand threads.
Loosen these nuts by rotating clockwise.
