G6M0095
1. Starter
A: REMOVAL AND INSTALLATION
1) Disconnect battery ground cable.
G2M0309
2) Disconnect connector and terminal from starter.
3) Remove starter from transmission.
4) Installation is in the reverse order of removal.
Tightening torque:
50±4 N⋅m (5.1±0.4 kg-m, 36.9±2.9 ft-lb)
B: TEST
1. MAGNETIC SWITCH
CAUTION:
The following magnetic switch tests should be per-
formed with specified voltage applied.
Each test should be conducted within 3 to 5 sec-
onds. Power to be furnished should be one-half the
rated voltage.
B6M0415A
1) Pull-in test
Connect two battery negative leads onto magnetic switch
body and terminal C respectively. Then connect battery
positive lead onto terminal 50. Pinion should extend when
lead connections are made.
B6M0416A
2) Holding-in test
Disconnect lead from terminal C with pinion extended. Pin-
ion should be held in the extended position.

3) Return test
Connect two battery negative leads onto terminal 50 and
onto switch body respectively. Then connect battery posi-
tive lead onto terminal C. Next, disconnect lead from ter-
minal 50. Pinion should return immediately.
2. PERFORMANCE TEST
The starter is required to produce a large torque and high
rotating speed, but these starter characteristics vary with
the capacity of the battery. It is therefore important to use
a battery with the specified capacity whenever testing the
starter.
The starter should be checked for the following three items:
1. No-load test
Measure the maximum rotating speed and current under a
no-load state.
2. Load test
Measure the magnitude of current needed to generate the
specified torque and rotating speed.
3. Stall test
Measure the torque and current when the armature is
locked.
B6M0418A
1) No-load test
Run single starter under no-load state, and measure its
rotating speed, voltage, and current, using the specified
battery. Measured values must meet the following stan-
dards:
No-load test (Standard):
Voltage/Current
11 V/90 A, or more
Rotating speed
TN128000-8311: 3,000 rpm, or more
TN128000-8321: 3,350 rpm, or more

B: INSPECTION
1. BATTERY
1) External parts
Check for the existence of dirt or cracks on the battery
case, top cover, vent plugs, and terminal posts. If
necessary, clean with water and wipe with a dry cloth.
Apply a thin coat of grease on the terminal posts to prevent
corrosion.
2) Electrolyte level
Check the electrolyte level in each cell. If the level is below
MIN LEVEL, bring the level to MAX LEVEL by pouring dis-
tilled water into the battery cell. Do not fill beyond MAX
LEVEL.
WARNING:

Electrolyte has toxicity; be careful handling the
fluid.

Avoid contact with skin, eyes or clothing. Especially
at contact with eyes, blush with water for 15 minutes
and get prompt medical attention.

Batteries produce explosive gasses. Keep sparks,
flame, cigarettes away.

Ventilate when charging or using in enclosed space.

For safety, in case an explosion does occur, wear
eye protection or shield your eyes when working near
any battery. Never lean over a battery.

Do not let battery fluid contact eyes, skin, fabrics, or
paint-work because battery fluid is corrosive acid.

To lessen the risk of sparks, remove rings, metal
watch-bands, and other metal jewelry. Never allow
metal tools to contact the positive battery terminal and
anything connected to it while you are at the same time
in contact with any other metallic portion of the vehicle
because a short circuit will be caused.
