E: INSPECTION
1. ARMATURE
1) Check the commutator for any sign of burns of
rough surfaces or stepped wear. If it has minor
wear, correct it by using sand paper (#300).
2) Run-out test
Check the commutator for run-out, and then re-
place if it exceeds the limit.
Commutator run-out:
Standard
3.1 mm (0.1220 in)
Service limit
Less than 3.8 mm (0.1496 in)
3) Armature short-circuit test
Check the armature for short circuit by placing it on
growler tester. Hold an iron sheet (thickness
gauge, etc. ) against the armature core while slowly
rotating the armature. A short-circuited armature
will cause the iron sheet to vibrate and to be attract-
ed to core. If the iron sheet is attracted or vibrates,
the armature, which is short-circuited, must be re-
placed or repaired.
4) Armature discontinuity test
Using a circuit tester, touch one probe to the Arma-
ture and the other to commutator. No continuity is
normal. If there is continuity, the armature is
grounded.
Replace the armature if it is grounded.
2. 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.
3. 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
9.0 mm (0.354 in)
Service limit
6.0 mm (0.236 in)

2) Brush movement
Be sure the brush moves smoothly inside brush
holder.
3) Brush holder discontinuity test
Using a circuit tester, bring one probe into contact
with positive side brush holder and the other with
negative side brush holder.
No continuity is normal.
4. SWITCH ASSEMBLY
1) Return spring check
Make sure the plunger returns to its original posi-
tion immediately after pressed-in then released.
2) Magnet switch continuity test
Be sure there is continuity between the terminals S
and M, and between terminal S and ground. Use a
circuit tester.
Also check to be sure there is no continuity be-
tween terminal M and B.
Terminal/Resistance:
S — M/1 Ω or less
S — Ground/1 Ω or less
M — B/1 MΩ or more
5. FRONT BEARING
Check the front bearing to make sure there are no
damage or rust.
Also, insert the shaft into front bearing to make sure
the front bearing rotates smoothly when the shaft is
rotated.
Replace the front bearing if faulty.

6. SHOCK ABSORBER BEARING CLEAR-
ANCE
Measure the outside (A) diameter of sliding part for
shaft shock absorber bearing.
Then, measure the inside (B) diameter of shock ab-
sorber bearing, and calculate the clearance.
If it exceeds the service limit, replace the oilless
bearing or shaft.
Shock absorber bearing sliding part:
Standard
18 mm (0.709 in)
Clearance:
Standard
0.03 — 0.061 mm (0.001 — 0.0024 in)
Service limit
0.1 mm (0.003 in)
7. REAR BEARING
Check the rear bearing, and replace the rear bear-
ing if there are damage, lock or rust.
8. PLANETARY GEAR BUSHING
Measure the outer diameter (A) of pin which is
press-fitted into shaft.
Then, measure the inner diameter (B) of planetary
gear bushing, and calculate the clearance.
If it exceeds the service limit, replace the planetary
gear or shaft.
Clearance:
Standard
0.035 — 0.065 mm (0.001 — 0.0025 in)
Service limit
0.1 mm (0.003 in)
9. SWITCH ASSEMBLY OPERATION
NOTE:
Test period of each test must be within short time (3
— 5 seconds).
1) Vacuum test
Disconnect the harness from terminal M and con-
nect it as shown in the figure. Make sure the pinion
gear sticks out.

2) Hold test
Make sure the pinion gear remains stick out even
after disconnecting terminal M in the above condi-
tion.
3) Return test
Connect the positive terminal to terminal S and the
negative terminal to terminal M and starter body to
pull the pinion gear at the main contact point. Make
sure the pinion gear returns to its original position
when the terminal S is disconnected.
10.PERFORMANCE TEST
The starter should be submitted to performance
tests whenever it has been overhauled, to assure
its satisfactory performance when installed on the
engine.
Three performance tests, no-load test, load test,
and lock test, are presented here; however, if the
load test and lock test cannot be performed, carry
out at least the no-load test.
For these performance tests, use the circuit shown
in figure.
1) No-load test
With switch on, adjust the variable resistance until
the voltage is 11 V, read the value of ammeter to
measure rotating speed. Compare these values
with the standard.
No-load test (standard):
Voltage/Current
Max. 11 V/90 A or less
Rotating speed
More than 1,720 rpm
2) Load test
Apply the specified braking torque to starter. The
condition is satisfactory if the current draw and ro-
tating speed are within specifications.
Load test (standard):
Voltage/Load
8 V/12.78 N·m (1.30 kgf-m, 9.4 ft-lb)
Current/Speed
370 A/850 rpm or more
3) Lock test
With the starter stalled, or not rotating, measure the
torque developed and current draw when the volt-
age is adjusted to standard voltage.
Lock test (standard):
Voltage/Current
3 V/900 A or less
Torque
15.42 N·m (1.57 kgf-m, 11.3 ft-lb)
