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 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.

Removal/Replacement
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-
