This belt replaces a 3/16" round O-ring belt. It is made from 1/8" cord. These are 92A durometer, they are much harder than normal 83A belts. These are rare, but can be tried as an option if more drive is needed. As they are much stiffer, they probably should be longer than the 83A twisted belts they are replacing.

Measure the twisted belt tip-to-tip, do not include the hook in the cut-length. Note crimping the standard metal hooks after installation may increase belt lifespan.
