Excavator Maintenance Tips
Due to the busy and tiring daily work of excavator hands, often ignore some details, but wait until the failure to overhaul. So today I will give you some excavator maintenance tips, I hope to help you.
Due to the busy and tiring daily work of excavator hands, often ignore some details, but wait until the failure to overhaul. So today I will give you some excavator maintenance tips, I hope to help you.
1. oil filter
Oil filter is a low maintenance cost of excavator parts, but the overall performance of the excavator has a role that can not be ignored. Strengthen the oil filter cleaning, timely replacement of the filter element, you can avoid short-term deterioration of the oil. Increase the daily maintenance of the crankshaft ventilation device cleaning and maintenance work, can also strengthen the maintenance of diesel engines.
2. Oil collector filter
Check if there is oil leakage from the oil collector filter, and check if the float head is clean and free of oil. If there is oil leakage, you can drill a small hole next to the float head to clean out the leaked oil and then weld the hole. This is because oil getting into the float head will cause the filter collector to sink. When the filter collector sinks to the bottom of the machine, the deposited dirt will be sucked up, which in turn will lead to clogging of the filter and the oil passage.
3. Temperature control
Not only to control the engine temperature, but also pay attention to whether the oil temperature and water temperature is normal, do not start without adding cooling water, resulting in the radiator boiling, which is very damaging to the engine.
4. Crankshaft and bearings
Routinely check the loss of crankshaft and bearings, as well as whether the screws are tightened, see the situation to add lubricant. If the loss of parts is serious, it is necessary to replace parts. At the same time, the oil drain plug on the filter housing should be checked frequently to clean up the dirt.
5. Coarse filter
First of all, turn the handle and remove the dirt on the filter piece of the coarse filter, and then start to clean the various parts of the filter, will be broken down and thoroughly cleaned. Check whether the system filter element reaches the replacement period and replace it. Listen to the rotor of the fine filter to see if there is a buzzing sound when the engine is turned back at low speed. If you can't hear it, you need to further overhaul the rotor, possibly because of excessive accumulated foreign matter, which needs to be thoroughly cleaned.
6. Air filter element
The air intake system of the engine is mainly composed of two parts: the air filter element and the air intake tract. Depending on the use of different situations, to regularly clean the air filter element, can use the method of high-pressure air blowing from inside to outside, the filter element in the dust blown out. Because the air filter element is paper, so the blowing. Pay attention to the air pressure can not be too high, so as not to damage the filter element. Air filter element in general in the cleaning 3 times after the need to replace, can not be used for a long time.
7. water tank
Water tank is often overhaul the parts of the machine hand ignored, because the water tank is loaded multiplied by water, so the daily work of few hands to clean it. In fact, the engine tank rust and scale is the most common problem. Rust and scale will limit the flow of coolant in the cooling system, reducing the role of heat dissipation, resulting in engine overheating, and even cause engine damage. Coolant oxidation also forms acids that corrode metal parts in the tank, causing breakage and leakage. Regular use of water tank strong efficient cleaner to clean the water tank, remove the rust and scale, not only to ensure that the engine works properly, but also to extend the overall life of the water tank and engine.
