Lang Tools Cylinder Leak-Down Tester Kit w/2-Gauges (CLT-2PB)

The Lang Tools Cylinder Leak-Down Tester Kit w/2-Gauges (CLT-2PB) is an essential diagnostic instrument for comprehensive engine assessment. This kit allows technicians and enthusiasts to accurately measure the integrity of an engine’s combustion chamber by quantifying the amount of compressed air that leaks past internal components. Unlike standard compression testers, the CLT-2PB identifies the specific source of compression loss, whether it be faulty valves, worn piston rings, cracked cylinder walls, or a compromised head gasket. Its dual-gauge design provides clear, precise readings, making it an invaluable tool for pinpointing problems and ensuring effective engine maintenance and repair.

KEY FEATURES AND BENEFITS:

• Dual Gauge Precision: Equipped with two M68 gauges, this tester offers unparalleled accuracy. One gauge displays the leakage percentage from 0-100%, clearly indicating the severity of the problem. The second gauge monitors the input air pressure from your shop compressor, ensuring consistent and controlled testing conditions.
• Comprehensive Adapter Set: The kit includes a 26-inch hose assembly with an M14 standard reach adapter, an M14 long reach solid adapter, and commonly found M10 and M12 adapters. This broad compatibility ensures the tester can be used across a wide range of gasoline engine types.
• Integrated Pressure Regulator: A built-in precision regulator allows for exact control over the air pressure delivered into the cylinder, crucial for obtaining consistent and reliable leak-down measurements. This feature prevents over-pressurization and ensures test accuracy.
• Clear Leakage Indication: The leakage gauge features a multicolored band, providing a quick visual reference for low, moderate, and high leakage levels. This intuitive design helps in rapid assessment of engine health.
• Portable Storage Case: The entire kit is housed in a robust plastic storage case, offering secure organization and convenient transport. This protective case ensures the longevity of the tools and keeps all components readily accessible.

HOW TO USE:

1. Prepare the Engine: Ensure the engine is at normal operating temperature. Turn off the ignition and remove all spark plugs.
2. Position Piston: Rotate the crankshaft to position the piston of the cylinder you wish to test at Top Dead Center (TDC) on its compression stroke. This closes both intake and exhaust valves.
3. Connect Tester: Thread the appropriate adapter (M10, M12, or M14) into the spark plug hole of the chosen cylinder. Connect the tester's hose assembly to the adapter.
4. Connect Air Supply: Connect your shop air compressor to the air inlet fitting on the leak-down tester.
5. Set Regulator Pressure: Open the air supply from your compressor. Adjust the regulator knob on the leak-down tester until the input pressure gauge reads the desired test pressure, typically 100 PSI (or as specified by the engine manufacturer).
6. Read Leakage: Observe the leakage gauge. The needle will indicate the percentage of air leaking from the cylinder. Simultaneously, listen for the sound of escaping air at different points to pinpoint the leak's origin (e.g., air from the exhaust pipe indicates a bad exhaust valve, from the intake manifold indicates a bad intake valve, from the oil filler cap or dipstick indicates worn piston rings, or bubbles in the radiator suggests a head gasket issue).
7. Test Other Cylinders: Repeat the process for each cylinder to get a complete picture of the engine's internal condition.
8. Disconnect and Store: Once testing is complete, disconnect the air supply, remove the adapter, and store all components in the provided case.
