DISASSEMBLY OF STARTING MOTOR.
1. Remove the frame screws from the commutator end head and pull end head and armature from frame.
Lift the brushes and lock in elevated position with brush springs. Use a puller to remove the end head
from the armature. Use special bearing puller to remove the sealed ball bearing from the armature
shaft.
2. Remove the frame screws that secure the gear housing to the frame. Remove bolts and nuts holding
the gear housing to the pinion housing and separate the two units. Pull Bendix shaft from pinion hous-
ing. Do not lose the steel spacer that is located on the pinion end of the shaft. Remove reduction gear,
woodruff key and steel spacer from shaft.
3. Turn the Bendix pinion until it locks in the extended position. Locate "spiral" pin and use a punch to
remove. Slide drive assembly off the shaft. Do not attempt to disassemble the drive and do not dip it in
cleaning solvent.
4. To remove the roller bearings from the gear housing, use an arbor press and the correct bearing arbor.
DO NOT HAMMER OUT. Each part should be cleaned and inspected for excessive wear or damage.
Bearings should be checked for proper clearance and evidence of roughness or galling. Oil and dirt
should be removed from insulation and the condition of the insulation checked.
BRUSHES.
Check the brushes to see that they slide freely in their holders and make full contact on the commutator. If
worn to half their original length or less, they should be replaced.
ARMATURE.
1. Check the commutator for uneven wear, excessive glazing or evidence of excessive arcing. If only
slightly dirty, glazed or discolored, the commutator can be cleaned with 00 or 000 sandpaper. If the
commutator is rough or worn, it should be turned in a lathe. (Refer to Figure 2.) The armature shaft
should be inspected for rough bearing surfaces and rough or damaged splines.
2. To test the armature for grounds, a set of test probes connected in series with a 110-volt light should
be used. Touch one probe to a commutator segment and the other to the armature core. If the test lamp
lights, the armature is grounded and should be replaced.
growler and slowly rotated by hand while a steel strip is held over the core so that it passes over each
armature core slot. If a coil is shorted, the steel strip will vibrate.
4. A quick check for opens can be made by inspecting the trailing edge (in direction of rotation) of the
commutator segments for excessive discoloration. This condition indicates an open circuit.
FIELD COILS.
1. Check the field coils for grounds (refer to Figure 4) by placing one test probe on the frame and the
other on the starter terminal. Be sure the brushes are not accidentally touching the frame. If the lamp
lights, the fields are grounded. Repair or replace.
2. Inspect all connections to make sure they are clean and tight and inspect insulation for deterioration.
