Hello, I have an intermittent popping noise when turning, side shifting and lifting. At the direction of mechanic I changed the pump but still have the noise. It seems to be coming from the pump area. It sounds almost like a gear skipping cogs but I can't find a schematic of what drives the pump from the engine. I am also wondering if it could be cavitation in the pump. Fluid is full and looks clean. I am wondering if it could be the filter is clogged but I'm not sure where the filter is located. Thank you for any help!

Mike
