RING / STOP RING REMOVAL
(1) Press the stop ring, by using an appropriate socket,wrench, to the snap ring side.
(2)After removing the snap ring (by using snap-ring pliers),
remove the stop ring and the 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 these parts 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 POINT

Using a suitable pulling tool, pull overrunning clutch stop
ring over snap ring.INSPECTION
COMMUTATOR INSPECTION
(1) Place the armature on a pair of V-blocks, and check thedeflection by using a dial gauge.
Standard value: 0.05 mm (JO20 in.)
Limit: 0.1 mm
(.004 in.)

UndercutI
(2) Check the outer diameter of the commutator.
Standard value: 29.4 mm (1.158 in.)
Limit: 28.4 mm (1.118 in.)(3) Check the depth of the undercut between segments.
Standard value: 0.5 mm (.020 in.)
BRUSH HOLDER
Check for continuity between brush holder plate and brush
holder.
The normal condition is non-continuity.
OVERRUNNING CLUTCH
1.While holding clutch housing, rotate the pinion. Drive pinionshould rotate smoothly in one direction, but should not
rotate in opposite direction. If clutch does not function
properly, replace overrunning 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
Inspect bushing for wear or burrs. If bushing is worn or burred,
replace front bracket assembly or rear bracket assembly.

SPEEDOMETER CHECK
(1) Assure tire pressure at standard value. (Refer to GROUP
- Specifications.)
(2)Gt the vehicle on a speedometer tester.
(3)Set free rollers securely on the floor according to the wheel-base and rear tread of the vehicle (when rear wheels
are to be set on free rollers).
(4) Raise the rear wheels on a jack and place rigid racks
to support the specified positions of the side sills (whenrear wheels are to be raised on a jack).
(5) Make sure the parking brake has been set.
cPWD>
(6)Attach anchoring bars on the tie-down brackets and secure
their ends to the anchor plates.(7) Make sure the tension on the right and left bars is the
same. Also be sure there is enough tension on each bar.(8) Attach a chain or wire to the rear tie-down hole. Make
sure the end of the wire or chain is secured firmly.
(9) Take all other necessary precautions.
(1O)Use a speedometer tester to measure the speedometer’s
indication error.

Repair or replace electricalcomponents.
Return parts or wiring to
their proper position.
Caution
1.Connecting a high tension cable to the noise
filter may destroy the noise filter and shouldnever be done.
2.Check that there is no external noise. Since
failure to do this may result in misdiagnosis
due to inability to identify the noise source,
this operation must be performed.3. Noise prevention should be performed by
suppressing strong sources of noise step
by step.
NOTE
1. Condenser
The condenser does not pass D.C. current, butas the number of waves increases when it
passes A.C. current, impedance (resistanceagainst A.C.) decreases, and current flow is
facilitated. A noise suppressing condenser
which takes advantage of this property is in-
serted between the power line for the noise
source and the ground. This suppresses noiseby grounding the noise component (A.C. or
pulse signal) to the body of the vehicle.
2. Coil
The coil passes D.C. current, but impedance
rises as the number of waves increases relativeto the A.C. current. A noise suppressing coil
which takes advantage of this property is in-
serted into the power line for the noise source,
and works by preventing the noise componentfrom flowing or radiating out of the line.

Ground parts by bonding.
Cases where the problem
is not eliminated by a single
response to one area are
common, due to several
bodypartsbeing
imperfectly grounded.

NOTEIf the
lifigate unlock switch or door key cylinder unlock switch is operated roughly, or if these switches have
been installed incorrectly or switches themselves are defective the ECU may not accept the warning or alarmcancelling signal. In such case, the alarm operation will take place when the door is opened using a key.
[When the door key cylinder switch has been shorted, however, if the ignition switch is turned ON, the ECU
judges the detection-switch as faulty and thereafter, it will prevent setting of (warning) alarm until the shorting
is corrected.]
If the
liftgate is opened using a key and is left opened when the door key cylinder switch system has a trouble
(wiring harness damage, open circuit, etc.), the ECU judges it as the
liftgate holding mode and does not producealarm even when the door is opened.
