Product review (1 stars): Until Amazon creates a proper "parts portal"... I would never bet on another appliance part here again.
If you think that typing the part number you need in Amazon's search bar means that they'll return you only the items that suitably meet that search criteria... guess again !!  This was not the motor I needed, and now I'm royally scr_w_d, I'm stuck with it.

DON't buy a dryer belt on Amazon - DON't buy a motor here.  Why ?  Because they don't have specifications shown, you cannot measure it and make sure of anything.  You won't know until you have it all in pieces and you've lost a hundred bucks and waited a week for the wrong part.

Whirlpool Corp makes Maytag, Whirlpool, Jennair and Kitchenaid... and I've had at least two product failures from each of these supposedly respected brands.  One closing note:  WHO is the engineer who came up with these stupid belt-driven dryers with rollers in the back but not in the front ?  In what universe did that sound like a good idea ?... To have a metal cylinder rattling for years between two strips of soft felt !!!?
