2-11 Blower Cone Installation
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 2-11.

Removal/Replacement
To Remove: First remove the center bolt (#1), washer (#2) and spacer (#3) from the taper-lock bushing (#5). See Figure 2-12. Next remove the (2) 1/4”-20 bolts (#4) and place them into the threaded holes of the taper-lock bushing (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 on to the engine shaft and into the impeller blade, aligning the non-threadedholes of the taper-lock bushing to the threaded holes of the impeller blade. Fasten by using (2) 1/4”-20 HHCS Grade #8 bolts, (1) spacer washer and (1) HHCS bolt w/ washer. Torque to the proper specifications in the torque chart on the back of this manual. Next, rotate the impeller blade to insure that the blade is clear of contact on all sides of the blower housing.
