Replaced broken washer belt, but drum still won't spin.

Today, my Amana washer started smoking and set off the smoke alarm in the house. It smelled like burning rubber. I took off the bottom front panel and found a busted washer belt. Replaced it as instructed here in the Solutions section (remove motor, replace belt, reattach motor, etc). Put wet clothes back into the drum. It spun for about 45 seconds. Then made a click sound (like static electricity) and stopped. The motor was hot. I found that after it cooled a minute or two, it would try to spin again, but just couldn't get going before it clicked off again. I can move the agitator in the drum manually counterclockwise very freely, but when I move it clockwise, I can only turn it about 1/4 of a turn before it seems to wedge in place. Any ideas what this could be caused from? I checked and rechecked my work.
