Hello everyone new to the thread, just want help and experts advice on isolating the problem. When i turn on the excavator and move the the machine or dig something it works fine but after working for a few minutes i noticed that digging and moving starts to slow down and finally its cant move. i've already replaced almost all of the internals on the main pump and tried cleaning the strainers and oil filters. any help or suggestions would be appreciated. thank you
Serial numbers would be a plus. You haven't provided enough information on what you have done. What is the engine doing? Have you cleaned the fuel strainer or replaced the fuel filters? What does the air filter look like? Are there any codes on the monitor system? How many hours are on this machine?
I had a power issue that ended up being my exhaust muffler being all clogged up. The power was down pretty much all the time not just after running for a while like yours. I had to cut the muffler open, clear it out and re-weld it together. Power back to normal!
