Hi. Does anyone know what the O-ring size is for the 3 point hydraulic piston on a satoh bison s650g? I measured the old one I have and I'm getting roughly 70mm o.d. x 60mm i.d. x 6mm thick. I know that the math of the above numbers don't add up, but, I'm not sure which one is correct.
Thanks.

You state you have "roughly" measured the outer and inner diameters of your existing seal. You could try taking your old seal to a hydraulic shop and see how closely they can match it. You could also check with Valley Power for the exact part number.
