"The early maintenance of the excavator is good, and the latter is less expensive". This is the Liteng's Excavator repair plant. According to the years of maintenance experience, the new excavator's friend is given a pertinent hint. Over the past ten years, the United States has maintained thousands of excavators, but many of the overhaul of excavators are actually caused by minor problems. It is like a person suffering from a small stomach disease, but improper maintenance, delayed treatment time in advance, and later dragged into gastric cancer. The result was a lot of money in vain. Now let's take a look at the eight practical skills of the new excavator maintenance.
1 before starting the engine, it must be done.
Check the engine oil level of the excavator engine, add oil; check the height of the liquid surface of the excavator's coolant (adding water); check the fuel level of the excavator (adding fuel); check the blockage of the air filter core; check the wire; check the horn to be normal; check the V hydraulic oil level (plus hydraulic oil); check the lubrication of the bucket; Check the water and sediment in the oil-water separator.
2 a new machine for a excavator should be done every 100 hours.
The rod end of the cylinder cylinder; the pin shaft of the bucket cylinder cylinder; the connecting pin of the movable arm and the bucket rod; excavating the head pin shaft of the motor arm cylinder cylinder; the pin pin; the bucket cylinder cylinder end; the bucket cylinder head pin; the half rod connecting pin; the bucket rod and the bucket cylinder end; check the oil position (oil) in the revolving mechanism box; the bucket cylinder head pin shaft; bucket rod;Connecting rod pin; drain water and sediment from fuel tank.
3 after the 250h maintenance of the excavator must be done:
The fuel filter element and the additional fuel filter element should be replaced; the clearance of the engine valve of the excavator should be checked.
4 every 500 hours of maintenance of the excavator must be done.
Replace the oil in the final drive box (only for the first time in 500h and later 1000h); clean the inner and outer air filter of the air conditioner system of the excavator; replace the hydraulic oil through air inlet filter core. Replace the oil filter core of the excavator, check the height of the lubricating grease of the rotary small gear wheel (adding lubricating grease), check and clean the radiator radiator of the excavator, the radiator fin of the oil cooler and the cooling radiator of the cooler, and replace the hydraulic oil filter core;
5 every 1000h maintenance of the excavator must be done:
Check the clearance of the turbocharger rotor; replace the oil in the rotary mechanism box of the excavator; check all the fasteners of the turbocharger; check the oil level of the shock absorber shell (back oil); check and replace the tensioning of the generator belt; replace the anti-corrosion filter core; replace the oil in the final drive box.
6 every 1000h maintenance of the excavator must be done:
Cleaning and checking the turbocharger, checking the generator, starting the motor, cleaning the filter net of the hydraulic oil tank, checking the gap (and adjusting) the engine valve, and checking the damper.
7 every 4000H maintenance of the excavator must be done:
Every 4000H increases the inspection of the pump and reduces the engine failure rate.
8 every 5000h maintenance of the excavator must be done:
The hydraulic oil of the excavator must be added or replaced.
If the machine is stored for a long time, it is necessary to wash the whole machine and dry it in the dry environment in the room, so as to avoid the original parts of the excavator, such as the piston rod of the hydraulic cylinder.
Only if the above "excavator maintenance homework" is done, I believe that the failure rate of your excavator will be greatly reduced. Accordingly, your maintenance cost will be greatly reduced, and the efficiency of your excavator will also be greatly improved.
