3. REMOVE GENERATOR REGULATOR ASSEMBLY
a. Remove the 2 screws and generator regulator assembly.
4. REMOVE GENERATOR HOLDER WITH RECTIFIER
a. Remove the 3 screws and generator rectifier holder.
5. REMOVE GENERATOR ROTOR ASSEMBLY
a. Remove the 3 terminal insulators from the rectifier end frame.
b. Remove the 4 nuts.
c. Using SST, remove the rectifier end frame. SST 09286-46011
d. Remove the plate retainer.
e. Remove the generator rotor assembly from the drive end frame.
NOTE: Do not drop the generator rotor assembly.
HINT: If the generator rotor is engaged too firmly, lightly tap the generator rotor shaft to remove it using a plastic hammer.
