Direct and Indirect Diesel Compression Tester - NEW

57mm Gauge with heavy-duty rubber bumper, 375mm of hose and quick connector.

This tester is suitable for testing car and light commercial vehicles with direct or indirect injection.

A Pressure relief valve allows repeated on-vehicle tests. It also includes a 90 degrees coupling adaptor for limited access applications.

A comprehensive test kit for both direct and indirect diesel injected engines.

Enables cylinder access through dummy injector and glow plug adapters.

Checks engine compression under cranking conditions.

Robust design with shock protected dual scale gauge. DIN16005, DIN16063, BS1780.

Applications: Audi, Citroen, Dacia, Daihatsu, Fiat, Ford, Isuzu, Lancia, Land Rover, Leyland/DAF, Mazda, Mercedes, Mitsubishi, Nissan, Peugeot, Renault, Rover, Seat, Toyota, Vauxhall/Opel(GM), VW, Volvo.

All Supplied in a bespoke blow moulded carry-case.

Test procedure

This is generally the preferred test method and avoids damage to the injector, and fuel system contamination. A comparison of pressure readings from each cylinder is a better guide to condition of valves or piston rings than a single cylinder test.
1. Run engine and warm up to normal operating temperature.
2. Disconnect supply to heater plug relay. Remove glow plug from cylinder and fit the appropriate dummy glow plug.
3. When cranking, stop the fuel supply by either: Disconnecting the fuel pump solenoid manually using the "pull to stop" knob when running tests are required unfasten the fuel line from the appropriate injector and fit plastic hose over end to re-direct fuel into a suitable container.
4. Couple the tester assembly on to the dummy glow plug.
5 Check the battery condition before cranking tests. Approximately 8-10 cranking cycles should be enough to indicate the cylinder pressure. For running test, start the engine and perform the compression test at idle or full revs as required. Check engine manufacturer's specification against results.
6. In order to repeat test on same cylinder, the gauge pressure can be released by pressing the relief valve button.
7. To repeat the test on other cylinders, stop the engine and connect as appropriate.

Dummy injector method

1. Run engine to normal operating temperature. Do not over-tighten. The gauge will display the compression of that cylinder.
2. Remove the appropriate injector. Fit the plastic pipe over the fuel line to redirect the fuel into a suitable container.
3. When a crank test is required ensure the battery is fully charged as this could influence the results.
4. Crank the engine to clear away from the port.
5. Place correct dummy injector in position using the clamp plate to ensure the mating faces are sealed.
6. Couple the tester assembly on to the dummy injector.
7. Start or crank the engine and perform test.
8. In order to repeat test on same cylinder, the gauge pressure can be released by pressing the relief valve button.
9. To repeat the test on other cylinders, stop the engine and connect as appropriate.
Check engine manufacturer's specification for compression results. A comparison of pressure readings from each cylinder is a better guide to condition of valves or piston ring than a single cylinder test. Specification
