Parts Inspection and Cleaning
NOTE
All bearings are sealed and require no lubrication. Do
not attempt to wash and lubricate bearings. If inspection
reveals a bad bearing, they must be replaced. Replace
bearings by pressing on armature shaft.
1.
Inspect all gears for wear, chipping, or binding.
2.
Inspect
all
bearings
for
wear
and
dirt
contamination. Be sure bearings turn smoothly
without binding. Replace any bearings or gears
which are found to be damaged or worn.
3.
Inspect for damage to gear drive and wear on
armature shaft. Replace armature if gear is
worn.
4.
Inspect commutator. Look for discoloration and
grooves. If grooved, turn commutator on lathe.
5.
Inspect solenoid wiring for dust and dirt. Look for
evidence of overheating. Check insulation for
discoloration and heat damage.
6.
Inspect solenoid contactor ring and solenoid
contactors for excessive wear, dirt, and pitting.
Replace if damaged or worn.
7.
Inspect brushes, brush springs, and shunt wires
for wear and/or damage. Replace, as necessary.
8.
Inspect motor fields for evidence of heat
damage. Check for shorting using a volt-
ohmmeter. Replace, as necessary.
9.
Clean all parts thoroughly prior to reassembly.
