Tools Required

A9912 0012B

Compression Pressure Tester

(001 589 76 21 00)

Measuring Procedure

1. Warm the engine up to normal operating temperature.

2. Remove the spark plugs using the spark plug wrench.

3. Place the diagram sheet to compression pressure

tester A9912 0012B (001 589 76 21 00).

4. Connect the adaptor to compression pressure tester

A9912 0012B (001 589 76 21 00) and install it into
the spark plug hole.

5. Crank the engine approx. eight revolutions by using

the start motor.

6. Compare the measurements of compression pressure

tester A9912 0012B (001 589 76 21 00) with the
specifications.

7. Measure the compression pressure of the other

cylinders in the same way.

8. If measured value is not within the specifications,

perform the cylinder pressure leakage test.

Notice

•

Discharge the combustion residues in the
cylinders before testing the compression
pressure.

•

Apply the parking brake before cranking the
engine.

Leakage Test

1. Warm the engine up to normal operating temperature.

2. Disconnect the negative battery cable.

3. Remove the spark plugs.

4. Check the coolant level by opening the coolant

reservoir cap and replenish if insufficient.

5. Open the engine oil filler cap.

6. Connect the tester to air pressure line and adjust the

scale of tester.

7. Install the connecting hose to spark plug hole.

8. Position the piston of No.1 cylinder at TDC by rotating

the crankshaft.

9. Connect the connecting hose to tester and measure the

leakage volume after blowing up 5 bar of compressed
air.

Notice

Measure the leakage volume in the completely
opening condition of throttle valve by pulling the
acceleration cable.

10. Perform the pressure test according to the firing order.

Notice

Firing Order: 1 - 5 - 3 - 6 - 2 - 4.

11. Compare the leakage pressure with the specifications.
