ARMATURE

1. Check commutator for any sign of burns of rough surfaces or stepped wear. If wear is of a minor nature, correct it by using sandpaper.
2. Check the commutator run-out and replace if it exceeds the limit. (Scheme 15) See «STARTER SPECIFICATIONS»(ref-167769-S26922706932004102100000) table under STARTER SPECIFICATIONS.
3. Check the depth of segment mold. (Scheme 16) See «STARTER SPECIFICATIONS»(ref-167769-S26922706932004102100000) table under STARTER SPECIFICATIONS.
4. Check armature for short-circuit by placing it on growler tester. (Scheme 17) Hold a iron sheet against armature core while slowly rotating armature. A short-circuited armature will cause the iron sheet to vibrate and to be attracted to core. If the iron sheet is attracted or vibrates, the armature, which is short-circuited, must be replaced or repaired.
5. Using a circuit tester, touch one probe to the commutator segment and the other to shaft. (Scheme 18) If there is no continuity, it is normal. If there is continuity armature is grounded. Replace armature if it is grounded.

BRUSH & BRUSH HOLDER

1. Measure the brush length and replace if it exceeds the service limit. See «STARTER SPECIFICATIONS»(ref-167769-S26922706932004102100000). (Scheme 19) Replace if abnormal wear or cracks are noticed.
2. Be sure brush moves smoothly inside brush holder.
3. Measure brush spring force with a spring scale. If it is less than the service limit, replace brush spring. See «STARTER SPECIFICATIONS»(ref-167769-S26922706932004102100000) table under STARTER SPECIFICATIONS.

OVERRUNNING CLUTCH

Inspect the teeth of pinion for wear and damage. Replace if it is damaged. Rotate the pinion in direction of rotation (counterclockwise). It should rotate smoothly. But in opposite direction, it should be locked.

PINION GAP

1. Measure the pinion gap while the pinion is pulled out. (Scheme 20) If the motor is running with the pinion forced endwise on shaft, disconnect the connector from terminal M of switch assembly, and then connect terminal M to ground terminal (-) of battery with a lead wire. Next, gently push the pinion back with your fingertips, and then measure the pinion gap.
2. If the pinion gap is outside specified range, remove or add number of adjustment washers used on the mounting surface of switch assembly until correct pinion gap is obtained.
