REMOVAL PROCEDURE
1. Turn off the engine on the SAE-300 HE machine.
2. Perform the Alternator Rotor Removal Procedure.
3. Perform the Alternator Stator Removal Procedure.
4. Label and disconnect all of the wires and cables that connect to the stator/frame assembly. See
Wiring Diagram.
5. Remove the mounting bolts from the generator feet.
6. Using a hoist and sling, very carefully lift the generator only enough so the generator frame will
clear the welder frame and can be removed. The sling should be positioned near the center of the
generator frame.
Carefully watch the clearance between the engine and any other components while hoisting,
especially the clearance between the engine fan, the fan shroud and radiator. Loosen or remove
the radiator if necessary.
7. Support the engine at the generator adapter plate end.
8. With the generator frame still supported by the sling (be certain the sling is positioned at the center
of gravity of the generator frame) and the weight of the engine resting on the supports that were
placed in the previous step, remove the screws securing the generator frame to the engine adapter
plate.
9. Carefully pry and wiggle the generator frame to free it from the adapter plate and then slide the
generator frame off of the armature. Adjust the height of the stator frame as needed to assure that
it can slide off the armature without damage to any of the armature or stator windings.
