Well you cannot see the piston, you have to take it apart to see if the O-rings and wiper are bad, if the loader is working its either the o-ring or the lift valve.We have anything you may need give us a call if we can help you 979-865-4002
Thanks Tommy, was hoping you would respond. Question, where do I find out how to pull the piston. There was a small piece of metal in the control valve but looked good, no scaring.
