My friends 200 Excavator has just started bypassing oil out the return line from the stick cylinder on top of the boom, even when the safety lever is in the raised-up position and nothing is supposed to operate.
Anyone know what valve is stuck on to bypass like this? No other function is being powered up when this happens. The machine has 8500 hours on it and just started to do this suddenly. The stick cylinder was removed from the top of the boom and repacked. It was then removed to re-test under pressure and passed. Oil still pours out the return line of this cylinder, even with the cab safety lever in the raised-up position.
Thanks in advanced for any input on what is happening.
