Noise from a generator may be caused by a loose drive pulley, loose mounting bolts, worn or dirty bear­ings, worn stator, or worn rectifier bridge. If the pulley and mounting bolts are snug and the noise continues, replace the generator. Refer to “Generator Replace­ment.”

Do not disassemble the generator. Separating the end frames will damage the slip ring end bearing. This generator is serviceable by complete replacement only.
