Has anyone had any experience with a problem of stopping leaks associated with the control valve. There are two end caps and three (sometimes four) sections of this control unit that control the dozer blade's lift, angle and tilt. there are four holes on both sides of the control blocks. leakage between the blocks is controlled by o-rings on one side. While there is not that much pressure, these blocks or at least one of them keep leaking not matter what I have done to stop it.. any suggestions out there would be appreciated. 550Gary
Serial number? What exactly have you done? Pictures?
