They hydraulic tailstock clamps seem to be frozen solid. The tail body moves OK, but it won't lock in position. The tail spindle slowly pushes it back until I get a limit alarm and the program stops. I have been putting a clamp in the way behind the tail body to keep it from moving, but I would like to get the pistons working. I can't turn the pistons using the big hex on top. I have used breaker bars and even an impact wrench.
I am afraid to apply much more force since I could open a hydraulics leak.
I have started looking for a tail stock from a scrap machine.
Any suggestions are appreciated.
