7. INSPECT FIELD COIL FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
lead wire and field coil brush lead.
If there is no continuity, replace the field frame.
8. INSPECT FIELD COIL FOR GROUND
Using an ohmmeter, check that there is no continuity between
the field coil end and field frame.
If there is continuity, repair or replace the field frame.
9. INSPECT BRUSH LENGTH
Using vernier calipers, measure the brush length.
Standard length:
1.4 kW type:15.5 mm (0.610 in.)
2.0 kW type:15.0 mm (0.591 in.)
Minimum length:
1.4 kW type: 10.0 mm (0.394in.)
2.0 KW type: 9.0 mm (0.354 in.)
If the length is less than minimum, replace the brush holder and
field frame.
10. INSPECT BRUSH SPRING LOAD
Take the pull scale reading the instant the brush spring sepa-
rates from the brush.
Standard spring installed load:
1.4 kW type:
17.6 − 23.5 N (1.79 − 2.41 kgf, 4.0 − 5.3 lbf)
2.0 kW type:
21.5 − 27.5 N (2.19 − 2.80 kgf, 4.8 − 6.2 lbf)

Minimum spring installed load:
1.4 kW type: 11.8 N (1.20 kgf, 2.7 lbf)
2.0 kW type: 12.7 N (1.29 kgf, 2.9 lbf)
If the installed load is less than minimum replace the brush
springs.
11. INSPECT BRUSH HOLDER INSULATION
Using an ohmmeter, check that there is no continuity between
the positive (+) and negative ( −) brush holders.
If there is continuity, repair or replace the brush holder.
12. INSPECT GEAR TEETH
Check the gear teeth on the pinion gear, idler gear and clutch
assembly for wear or damage.
If damaged, replace the gear or clutch assembly.
If damaged, also check the drive plate ring gear for wear or
damage.
13. INSPECT CLUTCH PINION GEAR
Hold the starter clutch and rotate the pinion gear clockwise, and
check that it turns freely. Try to rotate the pinion gear counter-
clockwise and check that it locks.
If necessary, replace the clutch assembly.
14. INSPECT REAR BEARING
Turn each bearing by hand while applying inward force.
If resistance is felt or the bearing sticks, replace the bearing.
15. INSPECT FRONT BEARING
Turn each bearing by hand while applying inward force.
If resistance is felt or the bearing sticks, replace the bearing.

16. DO PULL−IN COIL OPEN CIRCUIT TEST
Using an ohmmeter, check that there is continuity between ter-
minals 50 and C.
If there is no continuity, check and replace the magnetic switch.
17. DO HOLD−IN COIL OPEN CIRCUIT TEST
Using an ohmmeter, check that there is continuity between ter-
minal 50 and the switch body.
If there is no continuity, replace the magnetic switch.

REPLACEMENT
1. REPLACE REAR BEARING
(a) Using SST, remove the bearing.
SST 09286−46011
(b) Using a press, press in a new rear bearing.
2. REPLACE FRONT BEARING
(a) Using SST, remove the bearing. SST 09286−46011
(b) Using a press, press in a new front bearing.
NOTICE:
Be careful of the bearing installation direction. SST 09820−00030
3. REMOVE MAGNETIC SWITCH END COVER
Remove the 3 bolts, lead clamp, end cover, gasket and plunger.
4. INSPECT CONTACT PLATE FOR WEAR
Using vernier calipers, measure the contact plate for depth of
wear. Maximum wear: 0.9 mm (0.035 in.)
If the depth of wear is greater than the maximum, replace the
contact plate.

5. REMOVE TERMINAL KIT PARTS
(a) Using SST, loosen the terminal nuts.
SST 09810−38140
(b) Terminal C: Remove the terminal nut, wave washer , terminal insulator
(outside), O− ring, terminal bolt, contact plate and terminal
insulator (inside).
(c) Terminal 30: Remove the terminal nut, wave washer , terminal insulator
(outside), packing, O−ring, terminal bolt, contact plate,
terminal insulator (inside) and insulation paper.
6. REINSTALL TERMINAL KIT PARTS
(a) Terminal 30: Install these new parts:
(1) Insulation paper
(2) Terminal insulator (inside)
(3) Contact plate
(4) Terminal bolt
(5) O−ring

7. TIGHTEN TERMINAL NUT
(a) Put a wooden block on the contact plate and press it down with a hand press.
Dimensions of wooden block:
20 x 37 x 40 mm (0.79 x 1.46 x 1.57 in.)
Press force:
981 N (100 kgf, 221 lbf)
NOTICE:
Check the diameter of the hand press ram. Then calculate
the gauge pressure of the press when
981 N (100 kgf, 221 lbf) of force is applied. Gauge pressure:
If the contact plate is not pressed down with the specified pres-
sure, the contact plate may tilt due to coil deformation or the
tightening of the nut.
