Dear Shurika:

Brand and part numbers? Can the rod be extended by hand? Is the rod discolored or scored? With the rod stuck somewhere in mid-stroke, and "100 psi" applied to the piston end, how much leakage comes out the rod-end port? Same for the rod end, and leakage out the piston end? Leakage out the rod seal?
