There is confusion here--two people have reported different problems in the same thread and the replies have become confused as to what machine they're in reference to.
Bingwsguy, I wouldn't replace the pump until you have replaced the belts. Maytag uses special belts that are cloth covered. The reason is that the drive belt is designed to slip until the tub gets up to full speed--it acts like a clutch. Eventually the fabric wears thru to rubber, and you get the chirping, and burning rubber smell. They will SEEM like they have proper tension, and might even look like they're in fine condition to a casual eye. But if the fabric has worn through in even one small place, there will be chipring and smells, and eventually outright squealing. For this reason, you have to use the cloth covered maytag belt (or a cloth covered tractor-stye belt in the correct size). A plain rubber automotive-style belt will not work at all.
This is actually a clever design--let an inexpensive and easy to replace belt wear out, rather than an expensive clutch buried in the depths of the machine.
