TEST
NOTICE:
These tests must be done within 3 to 5 seconds to avoid
burning out the coil.
1. DO PULL±IN TEST
(a) Disconnect the field coil lead wire from terminal C.
(b) Connect the battery to the magnetic switch as shown.
Check that the clutch pinion gear moves outward.
2. DO HOLD±IN TEST
With battery connected as above with the clutch pinion gear
out, disconnect the negative (±) lead from terminal C. Check
that the pinion gear remains out.
3. INSPECT CLUTCH PINION GEAR RETURN
Disconnect the negative (±) lead from the switch body.
Check that the clutch pinion gear returns inward.
4. DO NO±LOAD PERFORMANCE TEST
(a) Connect the battery and ammeter to the starter as shown.
(b) Check that the starter rotates smoothly and steadily with
the pinion gear moving out. Check that the ammeter
shows the specified current.
Specified current: 90 A or less at 11.5 V

DISASSEMBLY
1. REMOVE DUST PROTECTOR
2. REMOVE FIELD FRAME AND ARMATURE
(a) Remove the nut, and disconnect the lead wire from the
magnetic switch terminal.
Torque: 5.9 N´m (60 kgf´cm, 52 in.´lbf)
(b) Remove the 2 through bolts.
Torque: 5.9 N´m (60 kgf´cm, 52 in.´lbf)
(c) Pull out the field frame together with the armature.
HINT:
Align the protrusion of the field frame with the groove of the
magnetic switch.
(d) Remove the O±ring from the field frame.
HINT:
At the time of installation, please refer to the following items.
Use a new O±ring.
3. REMOVE STARTER HOUSING, CLUTCH
ASSEMBLY AND GEAR
(a) Remove the 2 screws.
Torque: 5.9 N´m (60 kgf´cm, 52 in.´lbf)
(b) Remove these parts from the magnetic switch:
(1) Starter housing and clutch assembly
(2) Return spring
(3) Idler gear
(4) Bearing
4. REMOVE STEEL BALL
Using a magnetic finger, remove the steel ball from the clutch
shaft hole.

6. INSPECT BRUSH HOLDER
Check the brush holder insulation.
Using an ohmmeter, check that there is no continuity be-
tween the positive (+) and negative (±) brush holders.
If there is continuity, repair or replace the brush holder.
7. INSPECT CLUTCH AND GEAR
(a) 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 ring gear of the flywheel/drive plate
for wear or damage.
(b) Check the clutch pinion gear.
Hold the starter clutch and rotate the pinion gear counter-
clockwise, and check that it turns freely. Try to rotate the
pinion gear clockwise and check that it locks.
If necessary, replace the clutch assembly.
8. INSPECT MAGNETIC SWITCH
(a) Check the pull±in coil for open circuit.
Using an ohmmeter, check that there is continuity be-
tween terminals 50 and C.
If there is no continuity, check and replace the magnetic switch.
(b) Check the hold±in coil for open circuit.
Using an ohmmeter, check that there is continuity be-
tween terminal 50 and the switch body.
If there is no continuity, replace the magnetic switch.
9. INSPECT BEARING
Turn the bearing by hand while applying inward force.
If resistance is felt or the bearing sticks, replace the bearing.
