STARTING/CHARGING SYSTEMS
2. YOKE
Make sure the pole is set in position.
3. OVERRUNNING CLUTCH
Inspect the teeth of pinion for wear and damage.
Replace if it is damaged. Rotate the pinion in the
right direction of rotation (counterclockwise). It
should rotate smoothly. But in the opposite direc-
tion, it should be locked.
CAUTION:
Do not clean the overrunning clutch with oil to
prevent grease from flowing out.
4. BRUSH AND BRUSH HOLDER
1) Brush length
Measure the brush length, and then replace if it ex-
ceeds the service limit.
Replace if abnormal wear or cracks are noticed.
Brush length:
Standard
12.3 mm (0.484 in)
Service limit
7.0 mm (0.276 in)

2) Brush movement
Be sure the brush moves smoothly inside brush
holder.
3) Brush spring force
Measure the brush spring force with a spring scale.
If it is less than the service limit, replace the brush
holder.
Brush spring force:
Standard
15.9 — 19.5 N (1.62 — 1.99 kgf, 3.57 — 4.38
lb) (when new)
Service limit
2.5 N (0.25 kgf, 0.56 lb)

5. SWITCH ASSEMBLY
Be sure there is continuity between the terminals S
and M, and between terminal S and ground. Use a
circuit tester (set in "ohm").
Also check to be sure there is no continuity be-
tween terminal M and B.
Terminal / Specified resistance:
S — M / Less than 1
S — Ground / Less than 1
M — B / More than 1 M

6. SWITCH ASSEMBLY OPERATION
1) Using a lead wire, connect the terminal S of
switch assembly to positive terminal of battery, and
starter body to ground terminal of battery. The pin-
ion should be forced endwise on shaft.
CAUTION:
With the pinion forced endwise on shaft, starter
motor can sometimes rotate because current
flows, through pull-in coil, to motor. This is not
a problem.
2) Disconnect the connector from terminal M. Then
using a lead wire, connect the positive terminal of
battery and terminal M and ground terminal to start-
er body.
In this test set up, the pinion should return to its
original position even when it is pulled out with a
screwdriver.
