the blower wheel cracked and won't turn on the axle

removed the cover over the blower wheel. Released the clamp and retaining ring. put the new blower wheel back on the axle with the slot so it couldn't rotate on its own. Reset the clamp and rings, put the cover back on the blower and put the face of the dryer back on and rehooked the vent hose and electric and was back in business. Took about 20 minutes with the new parts
