STARTER MOTOR PARTS CLEANING

Never clean in a solvent such starter motor parts as 

the magnetic switch, brush holder, and armature. 
If they are soaked in a solvent, their insulation 
could be impaired. When these parts require 
cleaning, wipe off contamination with cloth.

1. Never soak the drive unit in a solvent. If it is 

washed in a solvent, the grease having been 
packed in the overrunning clutch at the factory will 
be washed out. Wipe the drive unit with cloth if it 
requires cleaning.

COMMUTATOR

AK304688

1. Support the armature with a pair of V block and 

turn it to measure the runout of the surface not 
rubbed by the brushes using a dial gauge.

Standard value: 0.05 mm or less
Limit: 0.1 mm

AK304689

2. Measure the diameter of the commutator.

Standard value: 29.4 mm

Limit: 28.8 mm

AK304690

Segment

Undercut

Mica

AB

3. Measure the depth of the undercut between 

segments.

Standard value: 0.5 mm
Limit: 0.2 mm

BRUSH HOLDER

AK201187

Push the brush into the brush holder to make sure 
that the spring is working on the brush.
If the spring is not working, replace the brush holder.

OVERRUNNING CLUTCH

Free

Lock

AB

1. Make sure that the pinion cannot be turned 

anti-clockwise and can be turned clockwise freely.

2. Check the pinion for abnormal ware and damage.

BRUSHES

Brush 
height

AB

1. Check the commutator contacting surface of each 

brush for abnormal roughness. Also check the 
height of the brush. Replace the brush holder if 
the height is lower than the limit.

Limit: 10 mm

2. When the contact surface of the brush is rectified 

or the brush holder is replaced, recondition the 
contact surface with sandpaper wrapped around 
the commutator.

ARMATURE COIL

1. Check the armature coil for short circuit as 

follows.

AK304692

Growler

AB

2. Set the armature in a growler.

CAUTION

Clean the surface of the armature thoroughly 
before performing the test.
3. While holding a thin strip of iron against the 

armature in parallel with its axis, turn the armature 
slowly. The armature is normal if the iron strip is 
not attracted to the armature or it does not vibrate.

AK304693

4. Check the insulation between commutator 

segments and armature coils. The armature coils 
are properly insulated if no continuity is present.

AK304694

5. Check continuity between a segment and another. 

There is no open circuit in the tested coil if there is 
continuity.

IGNITION SYSTEM

GENERAL INFORMATION

M1163000102018

This system is equipped with four ignition coils with 
built-in power transistors for each of the cylinders.
Interruption of the primary current flowing in the pri-
mary side of an ignition coil generates a high voltage 
in the secondary side of ignition coil. The high volt-
age thus generated is applied to the spark plugs to 
generate sparks. The engine-ECU turns the power 
transistors inside the ignition coils alternately on and 
off. This causes the primary currents in the ignition 
coils to be alternately interrupted and allowed to flow 
to fire the cylinders in the order 1-3-4-2.

The engine-ECU determines which ignition coil 
should be controlled by means of the signals from 
the camshaft position sensor and the crank angle 
sensor. It also detects the crankshaft position, in 
order to provide ignition at the most appropriate tim-
ing in response to the engine operation conditions.
When the engine is cold or running at high altitudes, 
the ignition timing is slightly advanced to provide 
optimum performance. Furthermore, if knocking 
occurs, the ignition timing is gradually retarded until 
knocking ceases.
