9-Piece Gasoline Engine Compression Tester Kit - RWKit for Compressor

• Package Contents: The motorcycle compression tester includes 1 x spring lock gauge; 4 x brass adapters (M10, M12, M14, M18); 1 x metal extension rod connector, 1 x straight and 1 x curved aluminum metal rod for direct testing and a rubber extension hose for long-range testing. The whole fuel pressure tester can provide you with great convenience. You don't have to buy these parts separately.
• Dual Scale Dial Gauge: Dual division pressure gauge, measuring range is 0-20 bar (0-300 psi), acrylic glass meter cover and with rubber protection to prevent scratches and provides excellent shock absorption performance. Thanks to the built-in check valve with pressure holding function, you can get accurate readings from our engine compression gauge.
• Function: The compression tester kit is designed to detect a variety of common engine faults, such as pop-off valve, carbon deposits, cracked cylinder head or faulty main gasket, faulty or worn piston ring assembly, burnt or damaged piston. The unique design of the safety valve is resistant to fuel pressure and safety.
• Application: Motorcycle compression tester with different sizes of turn and plug adapters, widely used in most types of gasoline engine cylinders and deep spark plugs, often in motorcycles, lawn mowers, cars, trucks, ATVs, etc. Note: This compression gauge is not suitable for diesel engines.
• Easy Storage: All parts are organized in a plastic case to protect the components and are easy to transport and store. The integrated motorcycle compression tester set allows you to test many engine systems.

With detailed instruction manual

How to use:

1. Start the engine and let it return to normal operating temperature. Once the engine has stopped, discharge all spark plugs;

2. Set the throttle fully open and press the pressure gauge fitting onto the cold spark plug hole;

3. The motors rotate the engine for 3 to 5 seconds at a speed of 100 to 150 rpm. At this point, the instrument needle gradually rises, but stops at a certain value. At this point, the indicator value is the cylinder compression pressure.

4. Press the button to set the pointer to zero.

5. According to the above steps, the measurement is repeated 2 to 3 times to improve the measurement accuracy.

Note:

1. Please make sure all parts are installed securely before performing the cylinder pressure test.

2. When the ignition is on, do not touch any part of the test equipment. Turn off the engine and remove the key before touching it.
