I would replace the pully and screw. If the hole is worn the screw will not tighten problerly Is the belt slipping when first started? The pully could be slipping a little on the shaft. Check it all out before replacing any parts. the motor brushes could be worn and making the noise when first started. Just suggestions for you to try.
