Hey guys just got my excavator back together. 2005 Volvo ec35, i bought a complete, used cabin/top section after mine caught on fire. everything works good except when I go to pull my dipper in, it wont pull it very well without curling the bucket (same stick) neither will really work without the other function being pushed too.... it is a pilot controlled joystick. Something stuck somewhere maybe? Swapped out switching valve (for alternate controls) and joystick, still no dice. Both joysticks share the same pilot control, there Is a "T" behind the seat and the left joystick works fine.
good day It sounds as if you have a couple of lines crossed - check out the feed to each of the main valves would be my suggestion. Kind regards Uffex
As mentioned above, but also verify P & T lines are clear. On the large platform machines, the RCVs have filtered inlet fittings. Make sure you don't have trash jammed up against one.
You were correct. Had one dipper line, and one bucket line crossed. All is good
Great you are fixed and up and running, nice you took the trouble to inform us. Kind regards Uffex
