the retainer between the hands, push and pull the
connector to free to disconnect and pull it out. Do
not use any tool at this time.
(4) Inspect if there is any dirt or the likes on the seal sur-
face of the disconnected pipe and clean it away.

damaging and mixing foreign objects by covering
them with a vinyl bag.
(g) Observe these precautions when connecting the fuel
tube connector (quick type).
(1) Do not reuse the retainer removed from the pipe.
(2) Must use hands without using tools when to remove
the retainer from the pipe.
(3) Check if there is any damage or foreign objects on
the connected part of the pipe.
(4) Match the axis of the connector with axis of the pipe,
and push in the connector until the retainer makes
a ºclickº sound. In case that the connections is tight,
apply little amount of new engine oil on the tip of the
pipe.
(5) After having finished the connection, check if the
pipe and the connector are securely connected by
pulling them.
(6) Check if there is any fuel leakage.
(h) Observe these precautions when handling nylon tube.

when connecting them.
(2) Pay attention not to kink the nylon tube.
(3) Do not remove the EPDM protector on the outside
of the nylon tube.
(4) Must not close the piping with the nylon tube by
bending it.

INSPECTION
1. INSPECT ARMATURE COIL
(a) Check the commutator for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the segments of the commutator.
If there is no continuity between any segment, replace the ar-
mature.
(b) Check the commutator for ground
Using an ohmmeter, check that there is no continuity be-
tween the commutator and armature coil core.
If there is continuity, replace the armature.
2. INSPECT COMMUTATOR
(a) Check the commutator for dirty and burnt surfaces.
If the surface is dirty or burnt, correct it with sandpaper (No.400)
or on a lathe.
(b) Check the commutator circle runout.
(1) Place the commutator on V-blocks.
(2) Using a dial gauge, measure the circle runout.
Maximum circle runout: 0.05 mm (0.0020 in.)
If the circle runout is greater than maximum, correct it on a lathe.
(c) Using vernier calipers, measure the commutator diame-
ter.
Standard diameter: 30.0 mm (1.181 in.)
Minimum diameter: 29.0 mm (1.142 in.)
If the diameter is less than minimum, replace the armature.
(d) Check that the undercut depth is clean and free of foreign
materials. Smooth out the edge.
Standard undercut depth: 0.6 mm (0.024 in.)
Minimum undercut depth: 0.2 mm (0.008 in.)
If the undercut depth is less than minimum, correct it with a
hacksaw blade.

3. INSPECT FIELD COIL
(a) Check the field coil for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the lead wire and field coil brush lead.
If there is no continuity, replace the field frame.
(b) Check the field coil for ground.
Using an ohmmeter, check that there is no continuity be-
tween the field coil end and field frame.
If there is continuity, repair or replace the field frame.
4. INSPECT BRUSHES
Using vernier calipers, measure the brush length.
Standard length: 15.5 mm (0.610 in.)
Minimum length: 10 mm (0.394 in.)
If the length is less than minimum, replace the brush holder and
field frame.
5. INSPECT BRUSH SPRINGS
Check the brush spring road.
Take the pull scale reading the instant the brush spring
separates from the brush.
Standard spring installed load:
17.6 - 23.5 N (1.79 - 2.41 kgf, 4.0 - 5.3 lbf)
Minimum spring installed load:
11.8 N (1.20 kgf, 2.7 lbf)
If the installed load is less than minimum replace the brush
springs.

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 drive plate ring gear 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 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
(See page ST-1 1).

If the contact plate is not pressed down with the spe-
cified pressure, the contact plate may tilt due to coil
deformation or the tightening of the nut.
(2) Using SST, tighten the nuts to the specified torque.

Torque: 17 N´m (173 kgf´cm, 12 ft´lbf)
NOTICE:
If the nut is over tightened, it may cause cracks on the in-
side of the insulator.
(g) Clean the contact surfaces of the remaining contact plate
and plunger with a dry shop rag.
(h) Install the plunger, new gasket, end cover and 3 bolts.
