Product review (5 stars): Beats buying a new motor...give it a try!
According to most of the web sites and parts lists, the only way to get this pulley is with the $150++ motor.
Check the position before you start hacking at it.  You need to make sure that it aligns with the belt.
I was able to get the old one off (gently breaking the tabs one at a time) without a puller (the right way).
The new pulley snapped right on and aligned correctly.
I felt really good about this fix.  A cheap faulty pump replacement bound up which grabbed the belt which caused the pulley to slip which heated up and ate the pulley.  I was really angry at the pump...eating my $150++ motor...
Then this part...give it a try...what do you have to lose?  10 minutes and $10...or just go get a new washer...
