PROCEDURE

Rotor Removal

1.Turn off the engine.

2.Open either, or both of the doors on the control panel end of the SAE-400 machine.

WARNING: Secure the doors in the open position using the door restraint system. If the machine does not have a door restraint system, remove the doors or securely restrain them to prevent them from falling closed.

3.Disconnect the battery cables. Disconnect the neg- ative cables first, and then disconnect the positive cables.

4.Remove the three nuts holding the battery retainer bracket. Remove the bracket and the batteries.

5.Remove the 5 screws securing the exciter covers, and then remove the upper and lower covers.

6.Disconnect and label the wires from the exciter brush holder. Remove the screws, and nuts holding the exciter brush holder and bracket assembly to the exciter frame, then remove the brush holder and bracket assembly. See Figure F.29

7.Bend the washer away from the rotor lock nut.

8.Using the 1-5/8” wrench to remove the nut from the end of the armature shaft, then remove the washer and sleeve collar.

NOTE: The sleeve collar will have to be removed with a small gear puller. Be very careful not to damage the rotor slip ring assembly.

9.Remove the rotor by pulling it off of the generator shaft. If necessary, remove the screws and nuts securing the lower front panel. This will allow the panel to be shifted enough to provide the additional clearance needed to remove the rotor.
