Used Hyd Cylinder removed from Barko Knuckleboom Loader. These are heavy duty double acting cylinders with 3 1/2" bore and 10" stroke.
Repair parts are available through the Barko dealer network. Be advised, we are unsure of the internal condition. At the very least, they probably need to be resealed. There are two pictured and there are two available.
Message if more info is needed.
