2-8 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#(K0130) 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 engaged (Figure 2-8).
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 2-9 for reference.
