SNAP RING/STOP RING REMOVAL

1.

Using  an appropriate wrench socket, push the stop ring
toward the overrunning clutch.

2.

Remove the snap ring with snap ring pliers and then remove
the stop ring and overrunning clutch.

STARTER MOTOR PARTS CLEANING

1.

Do not immerse the parts in cleaning solvent. Immersing
the yoke and field coil assembly and/or armature will
damage insulation. Wipe these parts with a cloth only.

2.

Do not immerse the drive unit in cleaning solvent. The
overrunning clutch is pre-lubricated at the factory and
solvent will wash lubrication from clutch.

3.

The drive unit may be cleaned with a brush moistened
with cleaning solvent and wiped dry with a cloth.

Limit: 0.1 mm

2.

Measure the commutator outer diameter.

Standard value: 29.4 mm

Limit: 28.8 mm

3.

BRUSH

1.

Check the brush for roughness of the surface that contacts
the commutator and check the brush length.

Minimum limit: 7.0 mm

2.

In case the contacting surface has been corrected or the
brush has been replaced, correct the contacting surface
by winding sandpaper around the commutator.

ARMATURE COIL SHORT-CIRCUIT TEST

1.

Place armature in a growler.

2.

Hold a thin steel blade parallel and just above while rotating
armature slowly in growler. A shorted armature will cause
blade to vibrate and be attracted to the core. Replace
shorted armature.

Caution
Clean the armature surface thoroughly before
checking.

3.

Check the insulation between each commutator segment
and armature coil core.
If there is no continuity, the insulation is in order.

ARMATURE COIL OPEN-CIRCUIT INSPECTION

Check the continuity between segments. If there is continuity,
the coil is in order.
