DISASSEMBLY SERVICE POINTS
AMAGNETIC SWITCH REMOVAL
Disconnect field coil wire from “M” terminal of magnetic switch.
BARMATURE / BALL REMOVAL
Caution
When removing the armature, take care not to lose the
ball (which is used as a bearing) in the armature end.
CSNAP RING / STOP RING REMOVAL
(1) Press stop ring off snap ring with a suitable socket.
(2) Remove snap ring with snap ring pliers and then remove
stop ring and overrunning clutch.
STARTER MOTOR PARTS CLEANING
(1) Do not immerse parts in cleaning solvent. Immersing the
yoke and field coil assembly and/or armature will damage
insulation. Wipe motor assembly with a cloth only.
(2) Do not immerse drive unit in cleaning solvent. 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.

REASSEMBLY SERVICE POINTS
ASTOP RING / SNAP RING INSTALLATION
Using a suitable pulling tool, pull overrunnig clutch stop ring
over snap ring.
INSPECTION
COMMUTATOR CHECK
(1) Place the armature in a pair of “V” blocks and check
the runout with a dial indicator.
Standard value: 0.05 mm
Limit: 0.1 mm
(2) Measure the commutator outer diameter.
Standard value: 32.0 mm
Limit: 31.4 mm
(3) Check the undercut depth between segments.
Standard value: 0.5 mm
BRUSH HOLDER CHECK
Check the continuity between brush holder plate and brush
holder.
If there is no continuity, the brush holder is in order.

OVERRUNING CLUTCH CHECK
(1) While holding clutch housing, rotate the pinion. Drive
pinion should rotate smoothly in one direction, but should
not rotate in opposite direction. If clutch does not function
properly, replace overrunnig clutch assembly.
(2) Inspect pinion for wear or burrs. If pinion is worn or burred,
replace overrunning clutch assembly. If pinion is damaged,
also inspect ring gear for wear or burrs.
FRONT AND REAR BRACKET BUSHING CHECK
Inspect bushing for wear or burrs. If bushing is worn or burred,
replace front bracket assembly or rear bracket assembly.
BRUSH AND SPRING REPLACEMENT
(1) Brushes that are worn beyond wear limit line, or oil-soaked,
should be replaced.
(2) When replacing ground brush, slide the brush from brush
holder by prying retaining spring back.
ARMATURE TEST
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.
ARMATURE COIL EARTH TEST
Check the insulation between each commutator segment and
armature coil core.
If there is no continuity, the insulation is in order.

INSPECTION PROCEDURE 28
Power steering fluid pressure switch system
Probable cause
The presence or absence of power steering load is input to the engine-ECU.
The engine-ECU controls the idle speed control (ISC) servo based on this input.
Malfunction of power steering fluid pressure switch

Improper connector contact, open or short-circuited
harness wire

Malfunction of the engine-ECU
Check the power steering fluid pressure switch.NG
Replace
OK
Measure at the power steering fluid pressure switch connector
A-101.

Disconnect the connector, and measure at the harness side.

INSPECTION PROCEDURE 29
A/C switch and A/C relay system
Probable cause
When an A/C ON signal is input to the engine-ECU, the engine-ECU carries out
control of the idle speed control (ISC) servo, and also operates the A/C compressor
magnetic clutch.
Malfunction of A/C control system

Malfunction of A/C switch

Improper connector contact, open or short-circuited
harness wire

Malfunction of the engine-ECU
Check the A/C compressor relay.
