FAQs
What does the kit include?
The kit includes a 63mm diameter gauge, a 380mm flexible hose, a clamping bracket, a right-angled hose adapter, non-threaded and threaded dummy glow plugs, sealing washers, and a plastic storage case.
What is the purpose of the dummy glow plugs?
Dummy glow plugs are used to adapt the kit to different engine types, ensuring compatibility across a wide range of diesel engines.
How do I interpret the gauge readings?
Compare the readings to the manufacturer's specifications for your engine. Low readings may indicate worn piston rings, valve problems, or other compression issues.
Can I use this kit on gasoline engines?
No, this kit is specifically designed for diesel engines and is not compatible with gasoline engines.
How do I maintain the kit?
Clean the gauge and components after each use, and store the kit in its plastic case in a dry place.
What is the purpose of the pressure relief valve?
The pressure relief valve is designed to release excess pressure, ensuring safe operation and preventing damage to the gauge.
What should I do if the gauge is damaged?
If the gauge is damaged, it may not provide accurate readings. In such cases, the gauge should be replaced or recalibrated by a professional.
Troubleshooting
Gauge reads zero or very low compression.
Ensure all connections are tight. Check for leaks in the hose or adapters. Verify that the engine is cranking at a normal speed.
Inconsistent readings between cylinders.
Make sure the engine is at operating temperature. Check for any obstructions in the glow plug or injector ports. Repeat the test and record the highest reading for each cylinder.
Hose won't connect properly.
Ensure you are using the correct adapter for your engine. Check the threads on the hose and adapter for damage. Try applying a small amount of oil to the threads to ease connection.
