Machine is a Deere 160dlc. When i go to boom down at any speed other than very slow. I get a quick grinding/cavitation noise from the boom cylinder circuit. Almost as of it cannot take or replenish the hydraulic oil fast enough when both boom cylinders are contracting under the weight of the boom. Pulled the right boom cylinder off being as it is a new to me machine with nearly 10000 hrs thinking there could be wear to the piston but everything looks ok. Is there a valve on the control valve that could not be opening/working fast enough for the escaping oil or something else I’m missing? Any help greatly appreciated!
