1987 MAZDA 626 engine oil

5 STARTER (DIESEL ENGINE, 2.0 KW TYPE)
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".

STEP 4 (STALL TEST)
This step is performed to determine if there is slippage of the friction elements or malfunction of the
hydraulic components.
Preparation
Check the following items prior to testing:
1. Engine coolant, engine oil and ATF levels.
2. Warm the engine thoroughly to raise the ATF temperature to operating level (50—80°C, 122—176°F).
3. Engage the parking brake and use wheel chocks at the front and rear wheels.
Pull the parking brake Water temperature

7. Perform the stall test for the following ranges in the same manner.
(1) D range (4) L range
(2) D range (Hold) (5) L range (Hold)
(3) S range (Hold)
Caution
Be sure to allow sufficient cooling time between each stall test.
Engine stall speed: D.S.L range 2170—2270 rpm
R range 2130—2230 rpm
Note
The stall test can be performed with the EC-AT Tester in place of a tachometer.

STEP 6 (OIL PRESSURE TEST)
This step checks line pressures for checking the hydraulic components and for oil leakage.
Line Pressure Test
Preparation
1. Perform the preparation procedure shown in STEP 4 (STALL TEST).
2. Connect a tachometer to the engine.
3. Connect the SST to the line pressure inspection hole (square head plug L)
Procedure
76G07B-031
1. Start the engine and check the idle speed in P range
Idle speed: 900 -so rpm
2. Shift the selector lever to D range and read the line pressure at idle.
3. Depress the brake pedal firmly with the left foot and gradually depress the accelerator pedal with
the right foot.
4. Read the line pressure as soon as the engine speed becomes constant, then release the accelera-
tor pedal.
Caution
Steps 3 to 4 must be performed within 5 seconds.
5. Shift the selector lever to N range and run the engine at idle for at least one minute.
6. Read the line pressure at idle and engine stall speeds for each range in the same manner.
