Removal/Replacement
Thread (1) 5/16”-18 jam nut P#(K0120) onto each end of
(2) 5/16”-18 x 2-1/2” HHCS P#(K0125). Now partially
thread the bolts into each of the two tabs located on the
blower housing. Place blower cone so the two tabs line
up with the bolts then tighten completely. See Figure 13.
To Remove: First remove the center 3/8” bolt and the (2)
washers from the taper-lock bushing (Figure14). Next
remove the (2) 1/4” bolts and place them into the
threaded holes (next to the holes they were removed
from). 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, hit the
base of the impeller, between each vein, with a hammer,
then try again.
To Replace: Place impeller blade over the engine shaft.
Slide the taper-lock bushing into 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. Fasten by using (2) 1/4”-20 x 1” HHCS
Grade 8 (torque to 15 ft. lbs), (1) spacer washer and (1)
3/8”-16 x 1” HHCS Grade 8 w/ washer.
