|
| caution |
Do not clamp the yoke assembly
with a vise.
|
Disconnect field the field coil wire from terminal M
of the magnetic
switch.
|
|
1.Press a long socket wrench
of appropriate size to the stop ring. Then tap the socket
wrench to remove the stop ring to the pinion gear
side.
|
|
2.After removing the snap
ring (by using snap-ring pliers), remove the stop ring and
the
overrunning clutch.
|
|
|
when removing the armature, do not
lose the ball placed at the end as a bearing.
|
|
Remove the pinion with power
supplied to the starter and the pinion in its popped-out
position.
| caution |
- When power is supplied to the starter,
the pinion pops out and
rotates. Keep your hands away from the
pinion at this time.
- The magnet switch may be extremely hot
after inspection. Be careful not to
touch it.
- Do not supply power to the pull-in coil
P for more than 10 seconds. Do not
supply power to the holding coil H for
more than 30 seconds. If these tine
limits are exceeded,
the coil(s) may overheat and burn
out.
- The pinion must be popped out
electrically by supplying the lever
since the
front bracket and lever may be damaged
when the stopper ring is
removed.
- When the starer is energized, current of
more than 100A flows. Thus, heavy-duty
cables (as thick as booster cables) must
be used to connect the starter for
inspection, and
all connections must be securely
tightened.

|
1.Connect the starter as
shown in the illustration. Here,
A: Switch,
B:
Switch,
C: Cable
M: Starter M terminal
S: Starter S
terminal
| note |
The following procedure must
be carried out with power supplied to the
starter. Thus,
the pinion must be removed within 30 seconds of
turning ON the power.
|
2.Supply power to the starter by turning ON
switches A and B. The pinion will pop out
and rotate.
|
|
3.Within 5 seconds of the
pinion’s rotation, turn OFF switch B to stop the
pinion
from rotating.
| caution |
With switches A and B turned
ON, power is supplied to both the pull-in coil
H. No voltage is applied to starter terminal B,
so current flows in the pull-in coil while the
pinion
is rotating. To prevent the pull-in coil from
burning out, switch B must therefore be turned
OFF within 5 seconds of the pinion’s
rotation.
|
4.Apply a suitable tubular tool to the pinion
stopper.
5.Lightly tap the tubular tool with a
hammer to remove the stopper ring from the pinions
ring from the pinion stopper ring groove.
6.Remove
the stopper ring and pinion.
7.Turn OFF switch A
to cut the supply of power to the starter.
| caution |
When the starter power is cut,
the pinion may pop in, causing the stopper
ring to go back into the ring groove. If this
occurs, switch ON the starter power and repeat
the procedure.
|
|
|
1.Pull the brush spring at
point A and raise the brush.
2.After raising the
brush, hold it in place with the brush spring as shown in
the illustration.
3.Remove the yoke
assembly.
|
|
|
1.Do not immerse the parts
in cleaning solvent. Immersion of the yoke,
field coil assembly or armature in solvent will cause damage
to the insulation.
|
|
|
2.Wipe clean with cloth if
these parts are dirty.
|
|
|
3.Do not immerse the drive
unit in cleaning solvent. The overrunning
clutch has been lubricated at the factory and cleaning with
a solvent will remove the lubricant.
|
|
|
4.Clean the drive unit using
a brush wetted with cleaning solvent and then wipe dry
with a cloth.
|
|
Using a suitable pulling tool, pull
the overrunning clutch stop ring over the snap
ring.
|
|
1.Install the pinion and the
pinion stopper in the direction sown in the
illustration.
2.Install the stopper ring in the
ring groove B if the pinion shaft assembly (overrunning
clutch).
|
|
3.Pulling the pinion hard,
secure the pinion stopper to the stopper ring.
