Removed old pulley, took about a half hour to hammer it off. Replaced with new pulley.
Once reassembled, the drive didn\'t work. Removed front and belt was still in place. Cleaned area around axle, reassembled. Most of the work involved removing and correctly replacing front cover. Had to tie the belt with cotton string to get the underside belt cover back on correctly. If you don\'t, the belt will jam in the cover and not engage with the transmission.
