(10) Inspect the commutator for scoring, wear, rough spots, and high mica. To repair the commutator, follow the
same procedure outlined in paragraph 191c.
(11) Inspect all threaded surfaces for corrosion, damage, and stripped threads. Replace all worn, corroded, and
damaged parts.
d. Reassembly.
(1) Install the field windings (41, 42, 44) and pole pieces (43) in the starting motor frame (40).
(2) Install the inner insulating washers (18) and plain washers (17) on the terminal stud (47) and push the stud
through the opening in the frame.
(3) Install the pole piece screws (48) but do not tighten them.
(4) Tap the frame (40) lightly with a soft-faced mallet to seat the pole pieces properly while tightening the pole
piece screws (48).
(5) Install the insulating washer (18), plain washers (17), lockwashers (15), and nuts (16 and 14) on the terminal
stud (47).
(6) Discard the drive end bronze bushing (2) if it was removed. Soak the new bushing in heated medium grade
engine oil and drain off excess oil before reassembly. Use a square shouldered mandrel or bushing driver
of proper size in the bushing to prevent it from collapsing and press the bushing into the drive housing (1).
(7) Install the key (12) on the armature shaft.
(8) Assemble the drive head (11), drive spring (7), and drive gear (6) on the armature shaft. Install and tighten
the lockwashers (8) and screws (9 and 10).
(9) Install the space washers (3, 4, 5) and assemble the drive housing (1) on the armature shaft.
(10) Install the armature assembly in the starting motor frame (40).
(11) If the brushes were removed, clinch and solder the new brush leads to make strong, low-resistance
connections.
(12) Install the bushing (36) and end plug (27) in the commutator end frame (19).
(13) Install the grounded brushes (34) on the commutator end frame (19).
(14) Attach the commutator end frame (19) to the starting motor frame (40) and see that all brushes are properly
installed in their brush holders.
(15) Install and tighten the thru bolts (21) and lockwashers (20).
