The generator does not require periodic lubrication. The rotor shaft is mounted on bearings. Each bearing contains a permanent grease supply. Periodically check the mounting bolts for tightness, and the drive belt tension. The drive belt is self-adjusting, within the operating limits of the tensioner. Refer to Drive Belt Tensioner Diagnosis in Engine Mechanical - 3.5L for tensioner information.

Important: Service the generator as a complete unit.
