I tried to work out the hydraulic issue this weekend. I raised and lowered the booms, and moved the bucket up and down. The bucket didn't make as much noises unless you used it to raise the machine off the ground (under load). The booms made a heck of a racket even shook the machine. Probably raised it up 5 or 6 times, I did this at idle as it was much worse at full throttle. Is there a better way to bleed the system. Still has the same problems, could it be anything else? Thanks for your inputs/suggestions.anytime that a system is opened that air has to be worked out and it can take some time depending what part of the hydro system was opened, but the air still must come out to get rid of the pulsing.
