Got 2 questions. First is kind of a general one. I’m getting a noise, like a banging/surging (kinda like water hammer in pipes) of hydraulic fluid when it’s at higher rpms. (i.e. driving or when you crank up the rpms lifting) my first thought was the pump is going. But then I was thinking maybe something in the valve body is causing it. Anyone have some ideas??? :beatsme
Second question is on a lull 644D-34. Same machine as the hydraulic noise problem. Does anyone know if you can change the hydraulic filter without draining the tank? I really don’t feel like having 33 gallons pour out when I’m not prepared to contain it all.
