ok , i don't have the mower deck on. with the clutch disengaged the pulley spins and makes a noise like the bearing is bad. i can stop the spinning with a broom and the noise goes away. With it engaged noise goes away and seems to be working ok. i can't put mower deck on because it's in pieces, but if the belt holds the pulley from turning it should be all right??? i think the pulley should not turn at all disengaged. Just looking for some experience and knowledge before i take it apart.
