Disassembly of the Starter/Generator to Service the Armature/Commutator
1. If the brushes are not removed, contact between the brushes and commutator as the commutator end
cover is being removed or installed could damage the brushes.
1.1. Lift the brush springs out of the notches in the brushes and pull the brushes back from the center
of the commutator end cover. The springs will rest on the sides of the brushes and help prevent
them from sliding towards the center of the cover (Figure 12-7, Page 12-5).
2. Remove the two bolts (20), and pull commutator end cover (23) free of the starter/generator housing
(24) (Figure 12-3, Page 12-4).
3. To separate armature (33) from output end cover (36), remove nut (41), lockwasher (40), pulley (39),
shaft key (34), spacer (37), and bearing retainer screws (43) (Figure 12-8, Page 12-6).
Bearing Cleaning and Inspection
1. Using a clean cloth, wipe the carbon dust from the two bearings. Inspect bearings by spinning them by
hand and checking for both axial (A) and radial (B) play (Figure 12-9, Page 12-7).
2. Replace the bearing if it is noisy, does not spin smoothly, or has excessive play. Check the bearings
and replace if rusted, worn, cracked, or if there is an abnormal color change in the metal of the bearing.
Bearings should be replaced if there is extensive wear or pitting on the balls or on the rolling surfaces.
Do not remove the bearings unless they are to be replaced.
