Compression pressure test of excavator engine

The compression pressure test of each cylinder of the excavator engine can check the decrease in engine power. Firstly, the color of the exhaust and the amount of air leakage in the crankcase should be checked, and attention should be paid to the inspectionExcavator lubricating oilThe consumption situation. Recheck the abnormal condition of the intake system, including the airFilterThe situation.

preparation:

1. Confirm that the clearance between each valve is correct.
2. Confirm that the battery is charging normally.
3. Start the engine until the temperature of the cooling water reaches the operating range.
4. Stop the engine and remove the hot wire ignition plug from each cylinder.
5. Install a pressure gauge with a connector at the position of the cylinder hot wire ignition plug (to prevent air leakage, the connector and pressure gauge must be tightened).

Testing:

1. Rotate the starter to rotate the engine crankshaft and record the compression pressure of each cylinder.
2. Repeat the measurement three times for each cylinder and calculate the average value.
