FAQS
What to do if the excavator has an oil leak?
To address oil leaks, inspect seals, fittings, and lines. Locate the leak, tighten any loose fittings, and replace worn or damaged seals and lines. Clean the area and recheck for leaks.
How often should the hydraulic oil be changed?
Usually the hydraulic oil is changed every 2000 hours or as recommended by the manufacturer.
What are the reasons why the excavator can rotate when starting, but cannot start?
1.There is no oil in the fuel tank.
2.The fuel filter and oil-water separator are blocked.
3.The low-pressure oil circuit does not supply oil.
4.The injection pump does not pump oil.
5.There is air in the oil circuit.
6.The valve timing is misaligned. The opening time of the valve is not coordinated with the stroke of the piston in the cylinder. For example, when the piston makes a compression stroke in the cylinder, the intake and exhaust valves are open, and fresh air is driven out of the cylinder, so that there is no combustion gas in the cylinder and it cannot start.
7.The solenoid valve of the injection pump is broken and is in a closed state, and the diesel cannot enter the high-pressure chamber.
How do you diagnose a faulty fuel injector in an excavator engine?
To diagnose a faulty fuel injector, listen for any unusual engine noises or misfires. Perform a balance test to identify which injector is causing the problem. Use a diagnostic tool to check for fault codes related to the fuel system. If necessary, remove and inspect the injector for signs of clogging or damage, and replace it if needed.
What causes hydraulic pump cavitation?
Possible low hydraulic oil level, high oil viscosity, or restricted fluid flow.
Solution: Refill hydraulic oil, use correct viscosity oil, check and clear restricted areas.
