Product review (5 stars): Aces
So far the spin cycle under test appears to be working, making it to 600 rpm. I have a Maytag 5500bwq from 2001. The fuse blew on the motor control board so the only option was a used control board or the new motor and board. Since this has been a great washer for 15 years and I did not wish to buy one that could probably be controlled by Russia, I bought the motor upgrade.  The way to find if the problem is your motor is by taking the back off the touch pad on top and finding the  directions for doing test runs.  To  determine it is in fact the motor, press the delicate and heavy soil buttons at the same time and hold until a 0 comes up. Then push the spin cycle button. The motor should turn the tub up to 60 or so on the decimal read out. This indicates 600 rpm, that the motor is indeed working. If it does not turn at all, it is the board that has failed.

The biggest issue was getting the motor in, as you have two pivot posts to work with. On YouTube there is a pretty decent demonstration, but when he shows that big hunk of plastic under the tub in the front, realize that all you have to do is unscrew two long bolts a little and slide it out. You cannot put the motor in without taking this out. And when it is gone the motor slides right in. When you bolt the motor in, in the back,  make sure the bolt and washer holding the motor up is slid to the peg above it. And tighten it down really well before putting the belt back on. As for the belt, run it on the motor first, then use a screw driver to slide it in the tub wheel. You will have to work it around with the screw driver.

The electrical just plug right into place. Directions are not great for the schematic, but they do work. This entire process takes about 1.5-2 hrs. from taking apart to putting together.
