(4) Remove the brush ground lead screws (30) and lockwashers (35). Remove the brush lead screws (32) and
brushes (34). If the brush leads are clinched and soldered, unsolder and unclinch their connections.
(5) Remove the commutator end frame (19) and drive out the end plug (27) and bushing (36).
(6) Drive out and remove the hinge pin (37), insulator pin (38), and stop pin (39).
(7) Pull out and remove the armature (13) and drive end (1) assembly.
(8) Remove the shaft spring screw (9) and lockwasher (8).
(9) Remove the head spring screw (10) and lockwasher (8).
(10) Remove the head (11), drive spring (7), and drive gear (6).
(11) Remove the key (12), inner space washer (5), center space washer (4), and outer space washer (3).
(12) Drive out and remove the drive end bushing (2).
(13) Remove the terminal stud nuts (14 and 16), lockwashers (15), plain washers (17), and insulating washers
(18).
(14) Push the terminal stud (47) down into the starting motor frame (40).
(15) Remove the pole piece screws (48) and pole pieces (43).
(16) Remove the field windings (41, 42 and 44), inner insulating washers (18), and plain washers (17).
c. Inspection and Repair.
(1) Inspect the starting motor frame and drive end housing for breaks and cracks. Replace if necessary.
(2) Inspect the drive gear for broken or damaged teeth, chips, pitting, and rough surfaces. Replace if damaged
or cracked.
(3) Inspect the drive head for broken or chipped lugs. Replace if defective.
(4) Inspect the bushings for wear, pitting, distortion, and damage. Replace if necessary.
(5) Inspect the field windings for damaged, peeling, frayed, or swollen insulation. Test for shorted, grounded,
and open circuits (par. 191c). Replace defective field windings.
(6) Inspect the pole pieces for damage, cracks, pitting, and breaks. Replace damaged pole pieces.
(7) Inspect the field connection insulation and replace the connection if the insulation is frayed or torn.
(8) Inspect the brushes and replace them if they are worn, oil soaked, or damaged. Unsolder and unclinch the
brush lead connections carefully. Solder the new leads in place to make a strong, low-resistance
connection.
(9) Inspect the armature for wear, pitting, and scoring. Inspect the armature shaft journals for wear, flaws,
pitting, and damage. Replace the armature if necessary.
