I have put the 619B backhoe on my B6000 over the weekend. The dipper arm goes up very slow and goes down very fast, like throwing a rock and there is nothing holding it . So it hammer the ground hard if I did not stop it within one second.
I did make all the cylinder go through a few full cycles. All other parts appear to move normally. Oil level looks fine. I looked around and did not see any leaks except from the oil vent hole.
Any idea where is the problem? I did not touch any of the hoses and connections. It used to work OK when I took it off a few month back. Hope I don't need to rebuild the valves (while I sort of suspected the valve and want to narrow down my hunt next time when I get there).
Also, I noticed the dipper arm droops slowly that may point to an internal leak?
