John Deere 5 804 liters lift arm lift is not high, what is the reason?

If this happens, it may be a problem with the system, or it may be a problem with pressure sensitivity, so you should check this area and do so.

This is estimated to be that some settings do not have that height, and the other is to see if there is anything stuck, because it is also related.

So take a comprehensive check.

The reasons why the lifting arm is not high are as follows.

First of all, check whether the machinery of the lifting arm is the place where the system is stuck, and check whether the power supply voltage of the lifting system is normal

If it can't be raised, then it may be because the power inside is not enough, or the hydraulic system is faulty.

The promotion is not high, it may be that the popularity is not good, it may be that his own works are not good, and it is possible, so it is possible that its quality is problematic.

If you find that John Deere's closed lifting lift is not high, it is generally either a lack of oil in it, or the gasket is leaking.

John Deeney is not tall in physical health, what is the reason?I think this may be caused by a short circuit in the circuit, or a setting flush error.

The main reason for such a high price may be because his interest rate is not high in the first place, so it will naturally not be born.

The reason why the lifting B liter is not high may be that there is a problem with the transmission system, which is the reason for the poor operation.

When the lifting robotic arm loses power, it is necessary to detect the smooth flow of the circuit to keep the voltage stable.

It should be a hydraulic problem, or it is caused by a lack of hydraulic oil.

Hello, probably a launcher issue. You can choose according to your actual needs.

Well, if you change places, the reason why this neuropathy is too low may be that it didn't work a few years ago.

The distributor is going to be broken, my car used to be like this, John Deere is this problem, the distributor was just changed yesterday. 780 yuan,

Hello, the automatic falling phenomenon of the tractor lifter may be that there is air in the hydraulic oil, or the hydraulic oil is too little and too thin, if it is not for this reason, it may be that the pressure oil limit valve of the gear pump is not returned, you can disassemble the distributor to check it, I hope it can help you,

Mine is also this problem, which is said to be a problem with the dispenser.

Hydraulic settling. The shutdown automatically falls back, and it will be used if it does not affect the use, and the repair cost is very high.

Is there not enough hydraulic fluid?

Mainly check whether the gap between the pins is too large, and whether the small arm pull rod and rocker arm are bent.

1. The pressure of the hydraulic pump is insufficient and the flow is unstable.

2. The oil seal of the hydraulic cylinder is worn.

3. Insufficient oil supply will also cause the failure of slow lifting of the digging boom.

4. The engine itself is weak.

5. There is slippage in the hydraulic pump drive.

6. If there is a leakage in the hydraulic pipeline, it will also affect the failure of the slow lifting of the digging boom.

7. The hydraulic pump is relieved, and the specified pressure cannot be reached, so that the excavator is powerless.

8. The hydraulic oil becomes dirty, and the slight stolen goods will greatly affect the power, and the heating of the hydraulic parts will become significantly larger, which can be used as a basis for judgment.

The small forklift distributor, hydraulic pump, and hydraulic steering machine are all new, and the boom will not work for a while.

Possible causes:

1. Cylinder leakage;

2. There is a problem with the main valve;

3. The oil pump is broken;

4. It may also be that the oil circuit is stuck.

The hydraulic system is not working properly, check the hydraulic system.

Check whether the lower boom lift cylinder is leaking,!Leakage in the boom lifting cylinder will cause slow lifting speed

The lifting speed is slow, it can be due to the problem of overuse of machinery, or it can be a heavy object.

There is a problem with the compensating solenoid valve that causes the excavator middle arm to open slowly, and the LS circuit throttle hole of the stick valve core is blocked (if the pressure is low, check whether the regeneration check valve is stuck or the throttle hole is foreign, and check the pressure compensation valve shuttle valve if the pressure is normal) causes the excavator middle arm to open slowly, and the reason for the slow opening of the excavator middle arm shared by the Global Excavator Repair Factory.

Fault solution: The cover of the hydraulic pump of the excavator is worn and needs to be repaired, the stick holding valve is faulty and the middle arm of the excavator opens slowly, the stick cylinder is faulty and the middle arm of the excavator opens slowly, the piston of the excavator cylinder is loose and needs to be tightened or reinstalled, the piston of the excavator is strained, it needs to be repaired or replaced, the middle arm relief valve is faulty, and it is necessary to check whether the cartridge valve and the two-position two-way valve in the stick holding valve are blocked or broken.
