Frame, Field, And Brush Holder Group
4. Install the frame and field assembly to the brush holder assembly.
4.1. Position the brush holder assembly (with installed brushes) over the terminal end of the frame and field assembly.
4.2. Attach the terminals of the insulated brush leads to the conductors in the frame and field assembly with the insulated brush screws.
Tighten
Tighten the insulated brush screws to 1.5 N.m (13 lb in).
Starter Motor Inspection (SD Series)
NOTICE: Do not clean the starter motor pans in a degreasing tank. Soaking parts will dissolve the permanent lubrication and may damage the electrical
insulation. This will shorten starter motor life.
Testing Armature For Short Circuits
1. Clean all parts by wiping with a clean cloth.
2. Inspect the bushing or armature bearing fit in the drive end frame, the lever housing, and the drive end frame housing. If the bushings or bearings
are damaged or worn, replace them.
^
Lubricate the bushings before assembling the starter motor. Avoid excessive lubrication.
^
Do not lubricate the roller bearings. They are permanently lubricated.
3. Inspect the armature for runout or scoring. Replace the armature assembly if the condition of the armature shaft is questionable.
4. Inspect the commutator for discolored or uneven conductors.
^
Do not turn the commutator
^
Do not undercut the insulation
^
Clean the commutator with 240 grit emery cloth. Blow away any copper dust present. If the commutator cannot be cleaned, replace the
armature.
5. Inspect the armature for short circuits.
^
Rotate the armature in a growler with a steel strip such as a hacksaw blade. Hold the blade on the armature parallel to the shaft. The steel strip
will vibrate when it finds the short circuit.
^
Shorts between the commutator bars are sometimes produced by brush dust or copper dust.
6. Inspect armature for opens.
^
Look for loose connections where the conductors join the commutator bars.
