5. Carefully remove the PMG stator from its
mounting pads and slide over the PMG
rotor. The magnets used in the PMG are
very strong and will resist removal of the
PMG stator. (Figure 6-16.)

PMG ROTOR REMOVAL
1. Remove the exciter armature and PMG
stator. (Follow instructions found earlier in
this section.)
2. Remove the snap ring that holds the PMG
rotor in place on the shaft. (Figure 6-17 and
6-18.)

3. Slide the PMG rotor off of the shaft.
(Figure 6-19.)

4. Remove the loading spring. (if the loading
spring is not on the shaft, check to see if it is
stuck on the back of the PMG rotor.).
5. On 430 frame generators a second snap
ring is used inboard of the PMG rotor.
(Larger generators have a step on the shaft.)
