My experience lies with Volvo for the past 20 years. Customer got my number, I made an assessment. Someone else two years ago was working on it, disappeared with the customers book as well. Person recommended new set of pumps, customer bought a new set, person installed, still no power. I come on scene, find broken solenoid on a regulator, replace with one from old pump that the customer still had. Regulator leaked, had to use an old one again. Ran machine to find that none of the functions could barely lift themselves. I found on screen this text. MECHATRO CPU CONT. FAIL. Don't know if that has anything to do with it, not being familiar with Kobelco. I will put a gauge on it on my next trip to get a better idea but have no specs. I do not suspect the pumps, the old ones and new act the same. I can lift the boom by working other functions. Any help/advise would be great.
