Sprocket Alignment and Installation
Sprocket and pulley alignment is very important. Proper alignment allows the load to be transferred equally
across belt width, which reduces wear and improves belt life.
1. Place a straight edge on the outside of the drive pulley, making sure that the straight edge touches the
outside and inside of the pulley.
2. Move the sprocket until the straight edge touches both outside edges and inside edges.
3. Make sure sprocket and pulley are properly aligned. Alignment should be within 1/4 degree. This is the
maximum “M” dimension of .05” per foot (1.3 mm per 305 mm) center distance.
Sprocket Installation
1. Inspect the bore of the sprocket and the bushings tapered surface. Remove any oil, dirt or grease.
2. Place bushing in sprocket inserting screw loosely
3. Place key in key set and slide sprocket to its desired location with the screw head facing outside. If
bushing goes on hard check shaft for burrs, remove if necessary.
4. Check for proper alignment of belts and evenly tighten bolts to recommended torque, see page 28.
