When power is applied to starter, armature rotates. As
armature rotates, drive pinion moves out on drive shaft
splines and into mesh with fl ywheel ring gear. When
pinion reaches end of drive shaft, it rotates fl ywheel and
cranks engine.
When engine starts, fl ywheel rotates faster than starter
armature and drive pinion. This moves drive pinion out
of mesh with ring gear and into retracted position. When
power is removed from starter, armature stops rotating
and drive pinion is held in retracted position by anti-drift
spring.
Starter Disassembly
NOTE: Do not reuse old retainer.
NOTE: Do not soak armature or use solvent when
cleaning. Wipe clean using a soft cloth, or use
compressed air.
1. Remove nut and disconnect positive (+) brush lead/
bracket from solenoid terminal.

either a retaining ring pliers or snap ring removal
tool, as described in Steps 4, and 5. Do not reuse
old retainer.
4. Remove thru (larger) bolts.

brush holder, brushes, springs, and locking caps.
Remove thrust washer from inside commutator end.
6. Remove frame from armature and drive end cap.
7. Remove rubber grommet and backing plate from
end cap.
8. Take out drive lever and pull armature out of drive
end cap.
9. Remove thrust washer from armature shaft.
10. Push stop collar down to expose retaining ring.

Inspection
Check drive pinion and inspect following areas:
● Pinion teeth for abnormal wear or damage.
● Surface between pinion and clutch mechanism for
nicks or irregularities which could cause seal damage.
● Check drive clutch by holding clutch housing and
rotating pinion. Pinion should rotate in only 1 direction.
