Poly Chain Sprocket Alignment and Installation
1. Place a straight edge on the outside of the drive sprocket, making sure that the straight edge touches
the outside and inside of the sprocket.
2. Move the sprocket until the straight edge touches both outside edges and inside edges.
3. Make sure the sprockets 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 the 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.

Sprocket alignment is very important. Proper alignment allows the load to be transformed equally across
the belt width, which reduces wear and improves belt life.
