@@tomhendricks316 you bet ! …. Im working on something else on my bobcat mg 50 , but figured id watch your video in case i need to service my cylinders some day
A 6 point socket is a lot less apt to round off a nut on high torque applications. The "hard plastic" may be teflon, try soaking it in hot water for a few minutes to soften it. It should shrink back after cooling.
The outer piston seal is PTFE 15% glass(PS1400). Yep Teflon with glass fibers in it. Heat shrink is made out of it so try a little heat from a hot air gun if you over stretched it when you pulled it over the piston to get shrunk to fit the cylinder and be careful not to over warm it for the fit over the piston... work with some haste to get it in the groove . Go from the bolt end on the piston to avoid over stretching. The machinist vise is a neat trick!
