of the taper-lock bushing 

(#9)

 and repeat Tip 1.

To Replace: 

First, place the impeller blade 

(#1)

 over the 

drive shaft 

(#13)

. Next, slide the taper-lock bushing 

(#9)

on to the drive shaft and into the impeller blade, aligning 
the 

non-threaded

 holes 

(#14)

 of the taper-lock bushing 

to the threaded holes of the impeller blade. Then, fasten 
by using two 1/4”-20 x 1”  HHCS

 (#10)

, one spacer 

bushing 

(#8)

 one taper lock bushing washer 

(#7)

, and 

one 3/8”-16 x 1-1/2” HHCS 

(#6)

. Torque all bolts to the 

specifications located in the chart towards the back of 
this manual. Last, rotate the impeller blade to ensure 
that the blade is clear of contact on all sides of the 
blower housing.

(#1)

, between each vein 

(#12)

loosen the taper-lock bushing hold.

Tips on removing impeller blade;

To gain impeller blade 

(#1)

 access, first remove the 

blower cone 

(#2)

 from the blower housing, located on 

the PTO assembly P#(A1821), by removing two blower 
cone bolts and nuts 

(#3)

. Next, remove the blower 

housing front 

(#4) 

by removing seven bolts and nuts 

(#5)

around the outer housing edge

.

 Refer to Figure 2-18.

To Remove:

 First, remove one 3/8”-16 x 1-1/2” HHCS 

P#(K1211) 

(#6)

, one taper-lock bushing washer 

P#(K0278) 

(#7)

 and one spacer bushing P#(S3242) 

(#8)

from the taper-lock bushing 

(#9)

. See Figure 2-18. Next, 

remove two 1/4”-20 x 1” HHCS 

(#10)

 and place them 

into the threaded holes 

(#11)

 of the taper-lock bushing 

P#(S4302). Last, gradually thread each bolt evenly into 
the taper-lock bushing, forcing the blade to break-away 
from the taper-lock bushing.
