DISASSEMBLY SERVICE POINTS

.

<<A>> ARMATURE AND BALL REMOVAL

CAUTION

When removing the armature, take care not to lose the ball
(which is used as a bearing) in the armature end.

.

<<B>> SNAP RING AND STOP RING REMOVAL
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.

STARTER MOTOR PART CLEANING

1. Do not immerse parts in cleaning solvent. Immersing the

yoke and field coil assembly and/or armature will damage
insulation. Wipe these parts with a shop towel only.

2. Do not immerse the drive unit in cleaning solvent.

Overrunning clutch is pre-lubricated at the factory and
solvent will wash lubrication from the clutch.

3. The drive unit may be cleaned with a brush moistened with

cleaning solvent and wiped dry with a shop towel.

INSPECTION

M1162001300072

.

COMMUTATOR CHECK
1. Place the armature on a pair of V-blocks, and check the

deflection by using a dial gauge.

Standard value: 0.05 mm (0.002 inch)
Limit: 0.1 mm (0.004 inch)

2. Check the outer diameter of the commutator.

Standard value: 29.4 mm (1.16 inches)
Minimum limit: 28.8 mm (1.13 inches)

3. Check the depth of the undercut between segments.

Standard value: 0.5 mm (0.02 inch)
Minimum limit: 0.2 mm (0.008 inch)

.

BRUSH CHECK
1. Check the brush for roughness of the surface that contacts

the commutator and check the brush length.Replace the
brush holder if this measurement exceeds the limit.

Minimum limit:

7.0 mm (0.28 inch)

2. .In the case contacting surface has been corrected or the

brush has been replaced, correct the contacting surface by
winding sandpaper around the commutator

OVERRUNNING CLUTCH CHECK
1. While holding the clutch housing, rotate the pinion. The drive

pinion should rotate smoothly in one direction, but should
not rotate in opposite direction. If the clutch does not
function properly, replace the overrunning clutch assembly.

2. Inspect the pinion for wear or burrs. If the pinion is worn or

burred, replace the overrunning clutch assembly. If the
pinion is damaged, also inspect the ring gear for wear or
burrs.

.

FRONT AND REAR BRACKET BUSHING CHECK
Inspect the bushing for wear or burrs. If the bushing is worn or
burred, replace the front bracket assembly or rear bracket
assembly.

.

ARMATURE CHECK
1. Check that the armature coil is not grounded.
2. Place the armature in a growler.
3. Hold a thin steel blade parallel and just above while rotating

the armature slowly in the growler. A shorted armature will
cause a blade to vibrate and be attracted to the core.
Replace the shorted armature.

4. Check the insulation between the armature coil cores and

the commutator segments. They are normal if there is no
continuity.

5. Check for continuity between the segments. The condition is

normal if there is continuity.
