The importance of second-hand excavator maintenance

In the world of second-hand excavators, maintenance is like putting a layer of armor on the machine. do you know? After an excavator has worked hard for 2,000 hours, it actually needs a deep spa. Just like us humans like to go for a massage to relax when we are tired, excavators also need such moments.

Let’s talk about the “cleanliness” of excavators – cleaning the hydraulic tank filter. This step ensures that its “blood circulation” system is unobstructed. Next, don’t neglect the health of the generator and starter motor, they are the “heartbeat” of the excavator. As for the valve clearance, it is the key to the “breathing” of the engine. Check and adjust it to make the engine breathe more smoothly.

Inspection and cleaning of turbochargers and shock absorbers are to make our excavators “run fast and jump high” and maintain their best condition. Of course, as the use time increases, we need to increase the inspection of the water pump after 4,000 hours, and replace the hydraulic oil at 5,000 hours. This is to ensure that its “blood” is fresh and healthy.

Now, let’s imagine this: you are a doctor and the excavator is the patient. Every inspection and maintenance is like giving it a physical examination. These regular “physical examinations” can prevent the occurrence of diseases, that is, avoid sudden failures, thereby extending the service life. Excavators of different models and working conditions may require different maintenance cycles and items, so specific issues must be analyzed in detail.

So, dear friends, don’t underestimate this maintenance work, it is the secret weapon that allows your excavator to run stably for a long time! Let us become the “health doctors” of excavators together and give them the best care!
