This blog article is about hydraulic problems and solutions for the Komatsu PC150LC-6 excavator. This also includes commentary from other readers on how they fixed their own machines.
Excess air in hydraulic tank
Most Komatsu PC150LC-6 PCL C-Series tractors encounter a common problem of excessive air in the hydraulic tank. This happens when there are gas bubbles in the oil which prevent it from reaching the engine. These bubbles interfere with flow of oil and gas to the engine, leading to loss of power and eventually shut down of the tractor. In other instances, all that is needed is to drain off the hydraulic fluid into another reservoir and replace it with new one. Alternatively, if this does not work then seeking professional help at repair center will be necessary for your tractor.
Testing the pressure relief valve
Another common problem with komatsu pc150lc-6 hydraulic systems is the failure of the pressure relief valve. Ultimately, this can make the system overload and fail resulting in injuries or even death. In order to test the pressure relief valve you will have to partially disassemble your machine. The first step is taking off its pump cover. Look for two screws that hold it in place, which we are going to remove together with a cover after that. On the upper part, there is black plastic housing under which pressure relief valve can be located at its bottom end.
This valve could cause the system to overload and fail if clogged. Remove cap and fill a small container with water (or oil if your machine has an oil-based system) in order to try it out.
Afterwards put back the cap and turn on the pump by trying to twist it. If it starts working then obviously it implies that maybe there’s something blocking inside. Otherwise, replace the cap and continue repairing your equipment as before.Pressure relief valves sometimes go bad on either side of these pumps at their bottom ends too.’Near me’, was what I heard while this hose was also removed.Don’t worry; every one of them will soon be mended!For a start; open any linked outlets so that you disconnect your heater from power sources like electrical outlets or plug ins whether they are available or not!
Testing the pilot filter
A pilot filter is one of the major problems in the system of komatsu pc150lc-6. It is situated in the pump discharge line to control the debris and oils. Failure by this filter could instigate an unstable system behavior. The best way to avoid this situation is by testing pilot filters. This can be achieved by using a clean stream of water while observing pressure gauge readings. A decrease in pressure below 50psi (3 bar) is an indication that you need to replace your pilot filter. Additionally, if you have any issues with your pump, make sure you check for any possible damage to it and fix all affected parts.
- To keep your hydraulic system in operation, it is important to test the pilot filter.
- This allows checking if there are no solids or water that will harm hydraulic systems
- Therefore, if clogged or faulty it should be changed immediately so as to maintain a smooth running state of your komatsu pc150lc-6 hydraulic system .
Testing the pilot oil filter
A popular issue experienced with Komatsu PC150LC-6 hydraulic system is when the pilot oil filter gets clogged. This can lead to reduced hydraulic pressure that in turn may cause the machine to fail. To test for this, remove the access panel located in the engine where the filter is fitted. In case there are signs of wear and tear on it then you should replace it immediately. Make sure you flush it well with clean oil before reinstalling back your access panel.
- One good way to keep your komatsu pc150lc-6 PCL C-Series plant operational effectively is by testing its pilot oil filter. It helps prevent impurities and debris from engine oil which keeps your machinery going smoothly.
- Immediately check your pilot oil filter if you observe any issues with your plant; its improper functioning or blockage can result into severe damage for both engines and devices being powered.
This is how you bleed air from a hydraulic system
It is an important step that you bleed the air from komatsu pc150lc-6 hydraulic systems to prevent hydraulic failures. You will find that when a komatsu pc150lc-6 hydraulic system fails, it has too much pressure in the system. This could make the pistons in the pump to rupture into pieces due to this high pressure. Therefore, it is important that you bleed off air from these systems so as to avoid such scenarios. This can be done by initially opening up the pump’s bleeding outlets.
By using either a screwdriver or lever, one can turn these valves. Consequently, when opened, you can start listening for where leakage by putting your ear very close to the valve is happening while bleeding air out of it. Every so often there may be some leaks; but at least they will know where they are and fix them if necessary. When having problems with komatsu pc150lc-6 hydraulic systems it is good to do away with any trapped air in it.
This involves opening a bleed valve on the machine’s hydraulic system allowing air to escape. Following this, close bleed valve then restart machine again . That way , you would have established pressure back into the hydraulic system and hence be able to repair it easily.
Replace the fuel lines
Fuel line problems are a common issue with komatsu pc150lc-6 hydraulic machines. The lines can become clogged and make the machine impossible to run. To avoid this, regularly change the fuel lines as they will keep your machine running well and prevent it from getting any problems.
One of the main complaints about komatsu pc150lc-6 hydraulic systems is that they have a tendency to fail in their fuel lines. This may be due to rusting or rupturing of the fuel line. Should this happen, then there will be difficulties when driving as this could lead to engine failure and you may need to repair your equipment. To prevent such failures it is vital that you perform a replacement on these lines every couple of years.
This action will guarantee you smooth operations of the car’s engine in future too because there won’t be any oddities coming up later on unexpectedly. It is also crucial to maintain clean lines that are free from debris; this further reduces chances for accidents emanating from fuel line failures.
Replace the hydraulic pressure sensor
One of the problems people often face with their komatsu pc150lc-6 hydraulic machine is a failure in hydraulic pressure. A pressure sensor that doesn’t function too well is the cause of this and should be replaced to guarantee normal operation. The very first thing you should do when your komatsu pc150lc-6 has low hydraulic pressure is to check if that sensor is faulty. This means, if it detects any issues with hydraulic fluid pressure in the system, it will send a signal to control unit.
You may need to recalibrate your machine or perform some other repairs after replacing the sensor so that it can work properly again. It is imperative to change out the pressure sensor on your komatsu pc150lc-6 if you are experiencing any problems with its hydraulic system. Doing so will help rectify any problems with the system and restore normal operation. A small device known as a pressure sensor checks for changes in hydraulic fluid presure which sends signals to a control unit.
Doing so will help rectify any issues within the system and restore normal operation. Replacing this can be done easily by any licensed technician. Therefore, act promptly when there are such malfunctioning mechanisms in your system!
