FAQS
How should Kobelco excavators be maintained in high temperatures in summer?

Kobelco excavator maintenance tips 1: Cooling to prevent air blockage In high temperatures in summer, the engine is prone to air blockage due to high speed and difficult heat dissipation, which makes it difficult to start the engine after stopping for a few minutes. Once air blockage occurs, the excavator driver should stop the engine immediately to cool down and eliminate the fault.

 

Kobelco excavator maintenance tips 2: Observe the water temperature gauge at any time to prevent water shortage When driving in high temperature weather, always pay attention to checking the cooling water volume and the water temperature gauge. When water shortage is found, immediately idle the engine to cool down before adding water, and be careful not to open the radiator cap immediately to prevent burns.

 

Kobelco excavator maintenance tips 3: Prevent engine oil from deterioration Lubricating oil is easily diluted by heat, resulting in poor oxidation resistance, easy deterioration, and even causing faults such as burning of the bearing and the shaft. Therefore, the crankcase and gearbox should be replaced with summer lubricating oil, and the amount and quality of the lubricating oil should be checked frequently, and replaced in time.

 

Kobelco excavator summer maintenance tips 4: timely cleaning of engine surface oil If the external oil of the engine is too thick, it will affect the heat dissipation and bury the hidden danger of failure of various parts. You can use the high-pressure spray method to clean the engine parts with a cleaning agent that does not corrode the body parts.

 

Kobelco excavator summer maintenance tips 5: prevent the water tank water temperature from being too high In summer, the cooling water of Kobelco excavators evaporates and consumes quickly. You must add enough cooling water before leaving the vehicle, and check the water level frequently during work. For single-cylinder diesel engines without a water temperature gauge, always pay attention to the red mark height of the water tank float. If the float cannot be used normally, it should be repaired in time. If the boiling phenomenon occurs during work, do not add cooling water directly. Stop the work, slow down the generator, and slowly add cooling water after the water temperature drops to avoid cracks in the water tank when it is cold.

 

Kobelco excavator summer maintenance tips 6: Ensure the best oil supply time In summer, the oil supply time of Kobelco excavators should be adjusted. If the oil is supplied too early, the engine will make a knocking sound and sometimes reverse; the oil supply time should not be too late, otherwise the engine will work weakly.

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 is the matter with the engine speed drop when the excavator is working? How to solve it?

8 reasons for the engine speed drop of the excavator, 6 solutions are here!

 

As the name suggests, engine speed drop means the failure of the engine speed drop during the operation of the excavator. There are two manifestations of speed drop, one is a slight speed drop within 200 revolutions, and the other is a serious speed drop above 300 revolutions, which is likely to cause the excavator to suddenly shut down. There are 8 main reasons for the engine speed drop of the excavator.

 

1. The diesel oil circuit of the excavator is faulty. Generally speaking, when the diesel oil circuit is blocked, it may cause the speed drop phenomenon.

 

2. The hydraulic system of the excavator has a fault, so that the hydraulic pump cannot change the displacement normally, causing the system pressure to be too high, and the speed drop may also cause a machine failure.

 

3. The output power of the excavator engine itself is insufficient, the output power is lower than the rated power, and the speed is too low. There is also a problem with the main pump.

 

4. The engine uses fuel of poor quality or the water content of the fuel is too high, which will lead to insufficient engine power and speed drop.

 

5. When the air intake system leaks or is blocked, the engine will be short of air supply, resulting in incomplete combustion of fuel, and there will be speed drop and black smoke failure.

 

6. Due to the large gap of the solenoid valve, the fuel supply is insufficient, which causes the engine to drop.

 

7. The joint of the fuel supply circuit of the fuel system is loose or the pipeline is broken, causing fuel leakage or foreign matter blockage, resulting in insufficient fuel supply. In addition to speed drop, it may also cause flameout.

 

8. There are many reasons for speed drop, such as incorrect valve clearance, wrong injection timing, damaged turbocharger, faulty brakes, etc.

 

Having said so many reasons for the speed drop of the excavator engine, what should we do when the speed drop occurs?
The solutions are all here!

 

1. First, check whether the diesel used in the excavator is deteriorated, whether there are impurities in the oil, and whether the oil circuit is blocked.

 

2. Check the valve clearance of the excavator engine and the speed of the engine.

 

3. Check the intake pipeline, clean the air pre-filter and air filter element, and start the engine again.

 

4. Check whether the speed drop of the excavator occurs when the engine is under load?

 

5. Carefully check the engine to see if the engine failure causes the speed drop of the excavator engine.

 

6. In addition, the electronic control, hydraulic system, fuel system, etc. need to be checked.
