When I raise my bucket I can't pull lever back to stop or nothing happens. I have to ease lever forward and bucket moves slowly with little power. Has anyone had same problem?
Not sure I follow but make sure the lever for your 3PH is centered (in the neutral position). Sounds like pressure is bleeding off somewhere and in some of the older BXs, the 3PH lever doesn't always go back to neutral.
The loader works the same regardless of engine speed. Seems to be more likely a control valve issue to me. Is this control valve difficult to dissasemble and rebuild?
Have you checked all of the hydraulic fittings? I had a similar
problem recently. A limb had pushed a hydraulic fitting apart. Loader
would dump and curl, but would raise very slow.
Hope this helps.
