I have an older Kubota B/L 4520A backhoe, I believe it was made by Woods for Kubota. It has two control levers that each control two valves, left is boom 4 way, and right is dipper and bucket curl. Lately the levers are getting very sloppy, especially the dipper/curl side. What happens is instead of pivoting, they want to twist. If they twist, then when you move the lever you don't get the cylinder action you were hoping for. The levers themselves are mounted in a rod end type ball joint which I suspect is the main problem. I can see how that would help the slop, but the twisting of the control levers is the real trouble I can't see how to address yet. I've tried adjusting the linkage but that hasn't helped. Anyone dealt with this before and have a suggestion?
