Alternator Installation and Maintenance

Operation & Maintenance Manual

22637300

INSTALLATION - COMMISSIONING

Assembly

All mechanical handing operations must be undertaken using approved equipment.

While being handled, the machine should remain horizontal (when travelling bar removed).

Handling

The generously sized lifting rings are for handling the alternator alone. They must not be used
to lift the alternator alone. They must not be used to lift the genset. Choose a lifting system
which respects the positioning of the rings (See Fig.13).

Coupling (Single Bearing Alternator)

Before coupling to the prime mover, check that both are compatible by:

•

Undertaking a torsional analysis of the transmission.

•

Checking the dimensions of the flywheel and its housing, the flange, coupling discs
and offset.

WARNING

When coupling the alternator to the prime mover, the holes of the
coupling discs should be aligned with the flywheel holes by cranking the
engine.

Do not use the alternator fan to turn the rotor.
