Cam Assembly Adjustment
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 A).
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.
