SR4 GENERATOR (THREE PHASE FULL WAVE EXCITATION & REGULATION Caterpillar


Permanent Magnet And Stator

Usage:

Remove Permanent Magnet And Stator

start by:

a) remove bridge rectifier and exciter armature

b) remove main exciter field

1. Disconnect wires (1) (11 through 16) from the regulator terminal strip.

2. Pull wires (1) from the generator and put the wires in the position as shown.

3. Remove the bolts that hold stator (2) to the bracket assembly and remove stator (2) from the generator.

4. Loosen the bolts and the nuts to remove permanent magnet (3) from the generator.
