To Replace: Place impeller blade over the engine shaft. Slide the taper-lock bushing (#5) on to 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 (#2) , (1) spacer bushing (#4) (1) taper lock bushing washer
(#3) , and (1) 5/16”-24 x 1” HHCS (#1) . Torque to the proper specifications in the torque chart on the back of this
manual. Next, rotate the impeller blade to ensure that the blade is clear of contact on all sides of the blower
housing.
2-19 Impeller Blade Removal/Replacement
To Remove: First remove the 5/16”-24 x 1” HHCS P#(K0428) (#1) , taper lock bushing washer P#(K0284) (#3) , (2)
5/16 Flat Wahers P#(K0042) and spacer bushing P#(S0159) (#4) from the taper-lock bushing P#(S0157) (#5) . See
Figure 2-19. Next remove the (2) 1/4”-20 x 1” HHCS (#2) and place them into the threaded holes of the taper-lock
bushing (#5) . 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.
