Kubota K008-3, 2012 mini excavator started having arm movement issue without cause. Everything works well except right hand forward (Main Boom down). No power there. Barely moves now. What should I be looking at?
Good day Please clarify which cylinder you have the issue. Kind regards Uffex
Arm Cylinder, #8. It will extend the arm out, but not contract it anymore. Thanks for your interest in helping!
Good day If the arm cylinder will power extending and not retracting points to a shock - port relief valve being the most probable cause of the problem. You can switch the valve from the opposing port to check it out. Kind regards Uffex
