I have an old (1980) Takamatsu cnc lathe that me and a friend of mine have been reworking. It has a Gamet hydraulic chuck on it and I wondering if anyone on here knows how to adjust the stroke of this particular chuck. If I adjust the nut one way, the chuck will pop and release like it's over-tightening, and then just a little bit the other way and it won't tighten at all! Any advise will be greatly appreciated!
