Product review (5 stars): Was tight but I stretched it!
This was for an old 1986-87 Maytag WU902. I could not get the belt on - too tight! - until I got the brainstorm to heat the belt in a frying pan of almost boiling water for a few minutes. Then I stretched it by hand and was able to thread it on the pump pulley, then ease it over the rim of the motor pulley while turning the pulley by hand. It seems to be on there tightly and the test wash was successful!
