Mine are exactly like these in that video.... The parts diagram shows a nut and an O ring on a piece at the end of the rod, but I could not get my rod out. There seems to be a retainer ring in there somewhere, by the diagrams. I couldn't figure out how to get it out to remove the the O ring at the end didnt get replaced. if I figure it out one day I will replace it.

But as for the V packing, yeah once you take the gland nut off, the packing is under it, you just pick at it until you get it all out.

I replaced mine with a set of PTFE ones from mcmaster-Carr... they are very hard with no squish, my piston still drips a little. I plan on getting a set of leather Vpackings and put one between each PTFE ring. As I read the leather ones make a better seal (so I read somewhere on the inteerwebs... who knows if its true)

Maybe the PTFE ones need tightened down more than I did.. I dunno. They are a lot harder than I thought they were, had I known that I would have ordered softer ones elsewhere.

The Vpacking removal and replacement turned out to be simple. Remove the gland nut, slide it off the rod, and remove n replace the packings.

if anyone knows how to get the rod out of these (exactly the ones in the video, on a WM3 loader) I'm all ears.
