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 20-5, Page 20-3).
2.
Remove the two bolts (20), and pull commutator end cover (23) free of the starter/generator housing (24) (Figure
20-1, Page 20-2).
3.
To separate armature (33) from output end cover (36), remove nut (41), lock washer (40), pulley (39), shaft key
(34), spacer (37), and bearing retainer screws (43) (Figure 20-6, Page 20-4).

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 20-7, Page 20-5).
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.
