Removal (Fig. 13)
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 nozzle and nozzle pulley from rear of outer
housing (see Nozzle Assembly Removal in this section).
4. Remove top grill to allow access to blower assembly
(see Guards Removal in the Service and Repairs sec-
tion of Chapter 6 -- Chassis).
5. Remove blower drive shaft from machine ( see Blow-
er Drive Shaft Removal in this section).
6. Remove rotor assembly (see Rotor Assembly Re-
moval in this section).
7. Remove cap screws and flange nuts that secure out-
er housing to fan housing mounts (item 20).
CAUTION
To prevent personal injury, make sure that fan
housing assembly is properly supported as it is
removed from the machine. Assembly weighs
approximately 70 pounds (31.8 kg).
8. Lift fan housing assembly from machine and set on
workbench with rotor shaft pointing straight up (Fig. 17).
9. Place inner housing on two (2) supports (2” x 4” or
equivalent). Then, place 9/16” (14.3 mm) thick support
between supports and outer housing (Fig. 16). This pro-
cess will support fan housing assembly to prevent unex-
pected shifting of any components during disassembly.
10.Loosen, but do not remove, eight (8) screws (item
15) that secure inner housing to outer housing.
11. Remove flange head screw (item 13) that secures
each stator vane (item 10) to outer housing. Carefully tilt
vane to free vane lugs from inner housing and remove
vane from assembly. Repeat for all twenty four (24)
vanes. Inspect each vane to make sure that mounting
lugs and screw threads are in good condition. Replace
any vane that shows signs of damage or wear.
12.Fully remove screws (item 15) that secure inner
housing to outer housing.
