There was a horrible screeching noise coming from the washer, and upon inspection I found that the retaining nut that attaches the cam to the machine was either improperly tightened to begin with or had worked itself loose causing the cam to wobble and the belt to work down the cam. The cam gear teeth became worn and the belt worked itself half off the cam and cut a hole in the protective plastic screen containing the whole ensemble. I purchased the belt, shield and cam kit. The parts are remarkably well designed compared to the original parts. The whole process took about 7 minutes. Works like new, if not better. Ensure the belt is properly aligned, and nut is tight. The cam should have little to no wobble when complete. Thanks AppliancepartsPROS.com!
