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 P#(E6009) so the
two tabs line up with the bolts then tighten completely.

Blower Cone Installation
Cam Assembly Adjustment
The cam assembly P#(A0422), which controls the
blower belt tension, comes from the factory pre-adjusted.
If the belt is too tight or becomes too loose, remove the
hair pin clip P#(K0099) from the belt tension rod
P#(K0326) and pull the “L” end of the rod out of it’s hole
in the cam assembly. The tension rod may then be
screwed out to tighten the belt or screwed in to loosen
the belt. Replace the “L” end into the top hole in the cam
and replace the hair pin clip. Adjust the cam stop bolt
P#(K1159) to allow the cam to rotate slightly over center
when the blower is disengaged (Figure A).
