Have a Montgomery Ward Dryer. Model FFT730880B Serial 90B16616. The belt broke and at which time the idler pulley came off. I saw a diagram simular to my pulley. When I put it back on like that diagram the belt and Idler pulley comes apart or off. Need a diagram of my particular model to see if I am putting it on correct.Thanks
Sorry to report I cannot find anything on that model (it is really old).
I suggest you try some other forums, and maybe they will be able to help you.
Good luck, sorry we could not be of beneft.
