giving the alternator the ability to cool to normal temperatures before returning to full charge status. While this is an extremely effective device for alternator protection, it should not be used as part of alternator maintenance. Continual alternator overheating indicates ventilation or charging system problems and repair is advised.

the generously-sized lifting rings are for handling the alternator alone. They must not be used to lift the genset. The choice of lifting hooks or handles should be determined by the shape of these rings. Choose a lifting system which respects the integrity and the environment of the alternator. 3.1.2 - Coupling 3.1.2.1 - Single bearing alternator

Replacement alternators. • Inspection & repair. • Alternator cleaning & drying. • Preventive & corrective maintenance. • On-site training.

If the connections are loose or dirty, remove and clean them thoroughly. If a connector or terminal is too far gone to save, replace it. Likewise, an alternator can't be expected to deliver its rated output if its belt is loose, worn or damaged. If the belt is still serviceable, adjust its tension. If it looks marginal, replace it.
