3. Outer diameter of the commutator
Replace the armature if the outer diameter of the
commutator is grind limit or less.
4. Roughness of the commutator surface
If the commutator surface is dirty, wipe it with a
cloth; if is is rough, repair it by using a lathe or fine
sandpaper.
Grind limit: 31 mm (1.22 in)
5. Segments groove depth
If the depth of the mold between segments is limit
depth or less, undercut the grooves by standard
depth.
Standard depth:
0.5—0.8 mm (0.020—0.031 in)
Limit depth: 0.2 mm (0.008 in)
Field Coil
1. Wiring damage
Check for continuity between the connector and
brushes by using a circuit tester. Replace the yoke
assembly if there is no continuity.
2. Ground of the field coil
Check for continuity between the connector and
yoke by using a circuit tester. Repair, or replace
the yoke assembly if there is continuity.
3. Installation of the field coil
Replace the yoke assembly
if
the field coil is loose.

Hold-in Test
1. After completing the pull-in test, disconnect the wire
from terminal M (with the pinion left ejected).
2. The hold-in coil is functioning properly if the pin-
ion does not return.
4BG05X-093
Return Test
1. Connect the battery between terminal M of the
magnetic switch and the body, as shown in the
figure.
2. Pull the pinion out manually to the pinion stopper
position.
3. The pinion should immediately return to its origi-
nal position when it is released.
4BG05X-094
No-load Test
1. After adjusting the pinion gap, form a test circuit
with a voltmeter and an ammeter.
Note
Use wires as thick as possible and tighten
each terminal fully.
2. Close switch "K" to run the starter.
If
the voltmeter
and ammeter show the following values while the
starter is running, it is normal.
Battery voltage: 11.0 volts
Current: 130 amperes or less
Gear shaft speed: at 4,500 rpm or more
3. If any abnormality is noted, check it according to
"INSPECTION".

TROUBLESHOOTING (G4A-EL) 7B
By following the above seven steps, the cause of the problem should be located.
As another guide to faster location of the causes of problems, the Quick Diagnosis Chart is included
at pages 7B—13, 14.
In this chart, a circle is used to indicate the components that might be the cause of trouble for 23
types of problems. It is only necessary to check those components indicated by circles, at each step
cf the troubleshooting process, in order to quickly locate the cause of the problem.
Quick Diagnosis Chart
The Quick Diagnosis Chart shows various problems and the relationship of various components that
might be the cause of the problem.
1. Components indicated in the "Self-Diag." column are diagnosed by the EC-AT control unit self-
diagnosis function.
The EC-AT Tester can be used for easy retrieval of these signals.
2. Components indicated in the "Adjustment" column indicate that there is a possibility that the prob-
lem may be the result of an incorrect adjustment.
Check the adjustment of each component, and readjust if necessary.
3. Input and outout signals of the EC-AT control unit for the components indicated in the "EC-AT
TESTER" column can be easily checked by using of the EC-AT Tester.
4. Components indicated in the "Stall Test" column can be checked for malfunction by the results
of the stall test.
5. Components indicated in the "Time Lag Test" column can be checked for malfunction by the results
of the time lag test.
6. Components indicated in the "Oil Pressure Test" column can be checked for malfunction by the
results of the oil pressure test.
7. Components indicated in the "Road Test" column can be checked for malfunction by the results
of the road test.
8. The checking, adjusting, repair or replacement procedures for each component is described in the
page(s) noted in the "Reference Page" column.

TROUBLESHOOTING (G4A-HL) 7B
TROUBLESHOOTING (G4A-HL)
GENERAL NOTE
In the event of a problem with the automatic transaxle, the cause may be in the engine, power train,
hydraulic control system, or electrical control system.
When troubleshooting, therefore, it is recommended to begin from those points that can be judged
quickly and easily. The recommended troubleshooting sequence is described below.
STEP 4: TIME LAG TEST
Check time lag of oil pressure supply
STEP 6: OIL PRESSURE TEST Check line, throttle, and governor pressures
This step checks conditions surrounding the automatic
transaxle.
This step checks the electrical control system.
• Function of the electrical control system
• Components
This step checks the power train. • Friction element slipping • Torque converter capacity
This step checks operation of the hydraulic control system. • Accumulators • Friction elements slipping • Regulating valves
This step checks functions of the electric control system and
hydraulic control system.
This step checks major points of the hydraulic control system.
• Oil pump • Line pressure control • Throttle pressure control
• Governer pressure control
STEP 5: ROAD TEST Check items on road test
• Shift point • Shift schedule
• Kick-down • Shift shock • Lock-up and overdrive inhibition
By following the above 6 steps, the cause of the problem should be located.
As another guide to faster location of the causes of problems, the Quick Diagnosis Chart is included
at pages 7B—42, 43.
In this chart, a circle is used to indicate the components that might be the cause of trouble for 20
types of problems. It is only necessary to check those components indicated by circles, at each step
of the troubleshooting process, in order to quickly locate the cause of the problem.

17. Install the oil pump shaft.
18. Install a new O-ring onto the turbine shaft.
76G07B-194

19. Fill the torque converter with ATF if it has been
drained and washed.
ATF type: Dexron II or M III
20. Install the torque converter in the converter hous-
ing while rotating it to align the splines.
Caution
a) Hold the torque converter in an erect posi-
tion when filling it with ATF, do not allow
the fluid to overflow.
b) If the converter does not fit in easily, do not
try to force it; install carefully.
21. To ensure that the torque converter is installed ac-
curately, measure distance A between the end of
the torque converter and the end of the converter
housing.
(A): approx. 25 mm (0.98 in)
22. Install the engine mount No.1
