Starter Cleaning and Inspection
Inspect the brushes for wear and damage.
Replace brushes if damaged or worn. Replace
weak brush springs.
Clean the commutator with 300-grade emery
cloth. If commutator surface is unevenly worn or
pitted, turn it on a lathe. Remove any trace of oil or
metal dust from commutator.
Check the armature on a growler for shorted turns
using a test light or meter. Inspect armature insu-
lation for indications of overheating or damaged
windings. Clean off any carbon deposits or foreign
matter which could contribute to failure of wind-
ings.
Check permanent magnets and make sure they
strongly attract any steel or iron object held inside
frame. Weak magnetism could cause excessive
RPM on No Load Current Draw Test on p. 132.
After disassembling the drive, clean each part with
Cleaning Solvent and inspect for wear and distor-
tion.
