Impeller Blade Removal/Replacement
To Remove: First, remove the 5/16”-24 x 1-1/2” HHCS P#(K1465) (#1) , Double Indented Washer P#(K0284) (#2) , (2)
5/16” Flat Wahers P#(K0042) (#4) and Spacer Bushing P#(S0159) (#5) from the Taper-Lock Bushing P#(S0157) (#6) .
Next, remove the (2) 1/4”-20 x 1” HHCS (#3) and place them into the threaded holes of the Taper-Lock Bushing (#6) .
Gradually thread each bolt evenly into the Taper-Lock Bushing forcing the blade to break-away from the Taper-Lock
Bushing. If the Impeller will not move, carefully hit the base of the Impeller, between each vein, with a hammer, then
try again.
To Replace: First, place the Impeller Blade over the engine shaft. Slide the Taper-Lock Bushing (#6) onto the engine
shaft and into the Impeller Blade, aligning the non-threaded holes of the Taper-Lock Bushing to the threaded holes of
the Impeller Blade.
Then, fasten the Impeller Blade by using (2) 1/4”-20 x 1” HHCS (#3) , (1) Spacer Bushing (#5) , (1) Double Indented
Washer (#2) , and (1) 5/16”-24 x 1-1/2” HHCS (#1) . Torque bolts to their proper specifications as listed in the Torque
Chart on the back of this Manual.
Finally, rotate the Impeller Blade to ensure that the blade is clear of contact on all sides of the Blower Housing. If there
is interference, remove the Taper-Lock Bushing, reposition the Impeller Blade further from the Blower Housing, re-
tighten the hardware, and then check for clearance.
