Aligning Pulleys
Pulley alignment is another important factor in
power transmission and belt life. The pulleys
should be parallel to each other and in the same
plane (coplanar) for optimum performance.
Each pulley can be adjusted by loosening the set
screws that secure them to their respective shafts.
