Excavator Volvo EC 300 DL Hydraulic system failure solution

The other day I had a Volvo EC300 of the year 2006 that left me with a strange problem, the machine only worked for a few minutes and then it turned off, when I tried to turn it on again, after several attempts it came on and worked for a few minutes and it turned off again.

Analyzing the fault codes to see if it gave me some information about the failure or what the system was doing, at first the machine came out with one fault code (Hydraulic inlet tank pressure sensor high signal) but then the fault code did not appear anymore and it just came out with (signal loss of pump pressure sensor) but as we all know, this fault code can be caused by many different things, such as high pressure filter clogged, hydraulic oil overheating, pump pressure sensor not giving signal, etc.

After analyzing these two fault codes I knew that this was a hydraulic failure but I did not know exactly what was causing the problem.

Excavator Volvo EC 300 DL Failure to start the engine solution

The problem of failure to start the engine for the EC 300DL excavator was solved as follows:

1. The automatic engine stop system is turned on. After turning on the ignition, the light flashes (see photo 1) and no error codes are displayed on the screen.

2. When you press the Start button, there is no reaction! No sound of a starter!

3. Checked according to instructions:

– The fuse in position 3 of the fuse box is intact.

– Battery voltage is normal 23V (photo 2).

– All relays are working properly.

4. After checking all this, I suspected that the automatic engine stop system was faulty or deactivated by a service engineer who worked before me with this machine!

5. It was decided to reconnect it, for this we took out all three plugs from each module (photo 3). Then we connected them back, after which we waited a few seconds and connected the battery itself back to its place and turned on the ignition again!

6. After that, everything worked fine! The engine started normally!

The Excavator Volvo EC 300 DL fuel pump is damaged solution

The Excavator Volvo EC 300 DL fuel pump is damaged solution.The excavator volvo EC 300 DL fuel pump is damaged. The construction site excavates the volvo car EC300DL fuel pump and the vehicle enters the city to purchase a new fuel pump, but the new fuel pump has been installed in the field, but there is still no sound of the oil pump, so what can it be?

1. The oil fill valve on the back of the engine was not open and the system was not ready to work.

2. The diesel engine cannot start because there is no oil pressure to start.

3. The diesel engine does not start because there is no power supply from the battery or from other sources (generators).

4. The diesel engine does not start because there is no electromagnetic valve signal to control it to start up or stop working.

5. There are two reasons for this situation: 

(1) The sensor on the oil pump does not send a signal to the computer control panel; 

(2) There is a problem with the computer control panel and cannot receive signals from sensors on various parts of the machine body.

The Excavator Volvo EC 300 DL brake pad is stuck solution

When the excavator Volvo EC 300 DL brake pad is stuck, it is necessary to perform the following work.

The action of the brake mechanism is carried out by pressing the brake pedal, which moves the piston in the main hydraulic cylinder, pushes the oil and compresses the brake pads against the steel disc. When the driver releases his foot from the pedal, the spring returns all parts to their original position.

Replacing brake pads on a car is not an easy task. It should be handled only by an experienced mechanic who knows all about brakes. The replacement of pads will require special tools and accessories. If you do not know how to safely remove a car from a garage or parking lot, do not risk it, contact a professional for help.

The Excavator Volvo EC 300 DL pinhole is broken or jammed solution

If the pinhole of the excavator is broken or jammed, first find out where the pinhole is broken. If it is a large and small pinhole, it is necessary to check whether there is a foreign object in the large and small pinholes. If there is no foreign object, whether the cylinder rod has been welded or not, if it has been welded, repair the cylinder rod welding point first; if there is no welding point, check whether the spring of the bucket cylinder is good or not.

If it is not good, replace it with a new one. (There are two springs on the bucket cylinder). If you need to replace the bucket cylinder spring and replace it directly, don’t change one by one.

If there are foreign objects in large and small holes, remove them and then check whether the shrapnel in large and small holes are damaged or worn out. If they are damaged or worn out, replace them with new ones. After solving these problems, see if the pump can work normally.

If there are no problems with large and small holes, you need to open the tank cover to check whether there are iron filings in the oil filter screen of hydraulic oil tank. If there are iron filings in hydraulic oil tank filter screen.

The Excavator Volvo EC 300 DL Engine overheating or overcooling solution

The most likely problem is that the radiatior is clogged. The radiator is located at the front of the excavator, with a large fan in front of it. You will need to remove the radiator cap with a 1-1/8 inch socket, and inspect inside the radiator. If you see any dirt or debris, then you will need to clean it out.

Most likely, you will need to use an air hose to blow out the dirt from inside the radiator. If it’s very dirty, you may want to wash it out with water instead of air. Be sure to use mild soap and warm water (like car washing soap).

Another possible problem is that the radiator does not have enough coolant in it. To check this, remove the radiator cap and look inside. The coolant should be right up to the top of the radiator. If it’s not, then you will need to add more coolant.

The The Excavator Volvo EC 300 DL turbocharger fails or cannot be started solution

The Volvo EC 300 DL excavator is one of the most common models in the market. When users encounter problems with this excavator, they will be anxious:

1. The turbocharger fails or cannot be started.

2. The engine speed is unstable during idle speed operation.

3. The engine speed changes when the working device is operated or loaded.

4. There is a serious delay in response when the accelerator pedal is stepped on.

5. If the above phenomenon appears, you need to check whether there is any dirt in the fuel pipe, filter and whether there are any precipitated impurities inside, if so, you need to clean it;

6. Check the air filter element and see if there is a lot of impurities in it;

7. Check if the air line has air leakage;

8. There may be a problem with the fuel supply of your car, so you need to check whether your injector has a problem;

The The Excavator Volvo EC 300 DL engine knocks and knocks solution

The Excavator Volvo EC 300 DL engine knocks and knocks, because the fuel supply is not enough, or the air pressure is not stable. In this case, we should check whether there is air leakage in the fuel line. If the pump does not suck enough fuel. If the line is blocked by debris, it must be cleaned up. We can also clean up the filter and see if it’s too dirty to work properly.

In addition, it should be noted that the excavator’s diesel engine has a large displacement. Therefore, when it works, it will consume a lot of fuel. At this time, we need to pay attention to fill the diesel tank in time to avoid insufficient fuel supply caused by knocking of the diesel engine.

The Excavator Volvo EC 300 DL Oil leaking from the engine solution

1. The oil leakage of the main oil pump seal is caused by the external leakage or the internal leakage. The external leakage is that the outer packaging of the pump body and the oil seal is damaged, and the internal leakage is caused by the loosening of the oil seal and the wear of the sealing surface.

2. The external oil leakage of the main pump assembly is mainly due to poor sealing performance of its outer circle, which may be due to poor quality or damage during installation or operation.

3. The internal leak of main pump assembly is mainly due to poor sealing between impeller and shaft or between impeller and volute chamber caused by wear, corrosion, etc., resulting in mixing of pressure oil and hydraulic oil in tank.
