Okay, ... I got into the back and removed the rear panel. Still no sign of a model number in the cramped place. There is a wide wing type of wheel located under the tub, ... intact. There is a belt, loose but I suspect it should be. However I did find something odd. I have about two inches of a material ... belt like, .. perhaps 5/8ths of an inch thick and about 1/8 of an inch thick. Ther are two worn impressions on the inner 'band' or natural run of this piece, ... meeting together in the middle to make a good 3/8th of an impression where they meet from what appears to be opposing sides. My guess is that this is perhaps the outter banding of a belt, which has created a gap in it's function by breaking off? Not much space to work but the belt that was there (which I suspect should be loose is a bit gummy by feel and appears to slip easily into the lower pulley if allowed/ I didn't pull on this as I didn't know if I should. Could this be a bad belt with a piece missing which has caused the problem and the clatter I've heard? Hope you can offer some advice ... my laundry area is a mess. Oh, do you make house calls to put things like this back together?? (Only kidding). Hope to hear from you soon.

Thanks for your time.
