I am working on an old Amana washer that needs a new belt as the old one is worn out and shredded. I was able to get the pump off OK .Some of these pumps are seized on the shaft and are very difficult to pull off. I noted that the idler arm is very loose on the pivot bolt. This causes the belt to ride up on the idler pulley too far to the top and actually runs part way on the lip of the pulley. Also the belt does not have very much tension which according to the manual is supposed to be that way???
Were you able to finally get the pump off and by chance did you note if the new belt was running in the proper position when everything was reassembled ?
