Product review (5 stars): Good Luck!
Product arrived ahead of schedule and was exactly what I needed.  Many reviews I read before buying the product said that it was difficult to install.  They said that they soaked it in hot water to stretch it.  NO NEED TO STRETCH IT!!!!!!  First, and most importantly turn off the breaker that supplies power to your dishwasher.  Then, it may be tough , depending on the installation and the clearance between the pulley(s) and the floor. What I did and it worked perfectly was:  Leave the belt "dry", slip the belt onto the motor pulley, from underneath and hold it in position. Slip the belt onto the pump pulley from underneath and "roll" it onto the pulley.  It may only go partially on to the pulley, but by turning the pulley while continuing to roll the belt, it will eventually slip into place.  Don't forget to lubricate the belt with the "Poly Lube" supplied with the belt. It'll be a tight fit, and may take a couple of attempts, but you'll get it on and be operating in no time. Good Luck !!!!!
