Do you know the top five considerations for buying used Kubota excavators?

I. Inspection of engines:

The engine is commonly known as the "heart" of an excavator, so be sure to check the engine carefully when buying a used machine.

1. During the test drive, listen to whether the engine has no noise, whether the power is strong, whether there is a slowdown while working, and also can enter the system to see if the exhaust is large. If the exhaust volume is large, it proves that the engine is working long enough to need major repair.

2. Also observe whether there is blue smoke, black smoke and white smoke when the engine is started.

3. Check the periphery of the engine for oil leaks and seeps; Water leaks and seeps occur.

4. Inspect high pressure oil pump, high pressure oil line, oil feed pump, oil feed line, etc.

II. Inspection of hydraulic pump system aspects:

A hydraulic pump is a power element of a hydraulic system whose role is to convert the mechanical energy of the original motivation into the pressure energy of the liquid. The oil pump in a mechanical system provides power to the entire hydraulic system. Therefore, the inspection of the hydraulic pump is also very important.

1 .Touch the hydraulic pump with your hand to see if there is a hand-shaking feeling . Then check whether the hydraulic pump has cracks and whether there is serious oil leakage .

2.Carry out the test run to observe whether the hydraulic pump is powerful and noiseless。See if walking is strong?Is there a sound？

3.Observe if the rotation is strong？Is it normal?Is there a sound？

4 .Are the rotating chassis and rotating gears related to clearance or greater wear ？

5 .Also pay close attention to the main control valve of the excavator , because the function of the main control valve is to control the action of the work , you must see whether the action of the excavator work is continuous and whether there is a pause .

6.To test whether the digging is powerful, dig a bucket of soil and lift it to the highest point to observe whether the oil cylinders have internal leakage。3

III. Examine the four wheels of the chassis:

1．Inspection of the four-wheel belt refers to the drive wheel, guide wheel, supporting wheel, carrying wheel and track.

All we have to do is examine the degree of wear on these parts carefully.

2．Check the chain and the tracks to see if the signs on the chain and machine information do not match. If they do not match, the chain has been replaced, and it also proves from the side that the machine is very worn.Finally, check the two walking motors to see if there is any deviation.

3．The chassis should also be looked at. It's not good if the wear is too severe.

IV. Inspect the arms and the hydraulic cylinders:

1．Observe the excavator boom, to see if the excavator boom cracks, welded traces, if the above situation, indicating that the machine has done a lot of strength, when buying, you have to think twice.

2．Secondly, observe whether the oil cylinder has bumped or leaked oil,

3．Are there scratches or spots on the piston rod？

Even if you buy this machine back and replace it with a new oil seal, it will continue to leak for a very long time.

1 .Inspect the electrical system :

2 .1 .Whether the circuit can work normally , and then enter the computer system to check the motherboard , if the system can be seen after entering the work , such as the number , pressure , maintenance mode , etc . , then prove that the computer board is normal .

3 .2 .Check if there is a fault code alert message on the display system ？

4 .3 .Check all the lines , throttle knob is normal , check the throttle motor is normal ？

5 .4 .Check the sensors , solenoid valves are normal ？

These are the top five considerations for buying used Kubota excavators. Please refer to them!
