I had replaced the bearings and seal and put the machine back together. When I ran the machine it would not spin. A quick search of the AppliancePartsPros website identified the problem -- a bad rotor position sensor switch. I ordered the part (2-day delivery), watched the video and easily made the repair.
I found that removing the rotor bolts using a socket wrench pretty tedious. I used the wrench to loosen the bolts and then a power drill with low tension to remove them. I used the power drill to replace them until they touched the rotor cover and then used the socket to tighten them. Much faster.
