2-13 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. Refer to Figure

Removal/Replacement
To Remove:
To Replace
First remove the 3/8”-16 x 1-1/2” HHCS
P#(K1211)
, taper lock bushing washer P#(K0278)
and spacer bushing P#(S3242)
from the taper-
lock bushing (#5). See Figure 2-14. Next remove the (2)
1/4”-20 x 1” HHCS
and place them into the threaded
holes of the taper-lock bushing P#(S4302)
.
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.
Place impeller blade over the engine shaft.
Slide the taper-lock bushing
on to the engine shaft
and into the impeller blade, aligning the
holes of the taper-lock bushing to the threaded holes of
the impeller blade. Fasten by using (2) 1/4”-20 x 1”
HHCS
, (1) spacer bushing
(1) taper lock
bushing washer
, and (1) 3/8”-16 x 1-1/2” HHCS
. 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.
