Poly Chain Sprocket Alignment and Installation
Sheave or 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.
1. Place a straight edge on the outside of the drive sheave or sprocket, making sure that the straight edge
touches the outside and inside of the sheave or sprocket.
2. Move the sheave or sprocket until the straight edge touches both outside edges and inside edges.
3. Make sure the sheaves or 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.
Sheave or Sprocket Installation
1. Inspect the bore of the sheave or sprocket and the bushings tapered surface. Remove any oil, dirt or grease.
2. Place bushing in the sheave or sprocket inserting screw loosely.
3. Place key in key set and slide sheave or 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 33).
