Freeman loader cylinders

Looking for a little advice here group...I am trying to find some parts to repair the leaking single acting cylinders on my Freeman manure loader for my JD 420. I tore into one of the cylinders to get an idea of what I may need. Everything looks pretty good, but I clearly need to replace what the parts diagram calls "v leather packings" I did find a few similar products online, but none of the have the same dimensions that I am looking for. I am considering using what is called a Type B rod seal or Type B PolyPak. Anyone have any experience with this? My biggest concern is that I cannot find the exact OD that I need. My cylinder rod has a 2 1/4" ID, which is no problem, but the packing gland where the seals go is about 3.050" and I'm afraid that 3" would be too small and 3 1/8" too big. Any thoughts?
 
Mike - I have an old Freeman loader that uses the V packing. My old neighbor was a machinist and helped me repack the cylinders. We used a length that was longer than the circumference around the rod and cut it to fit. I remember that he cut one end in a swallow tail configuration, and the other end the opposite, so they would fit together. On mine, there was room to stack several pieces of v packing, overlapping the joints so they weren't lined up. It worked good. I used it on a JD with about 1200 PSI hydraulic pressure.

My cylinders did not have a piston in them - only a rod with a large external snap ring to keep the rod in the cylinder.

I would get the packing too large and cut it down. Maybe someone else has a better idea.

Allis Chalmers used Freeman loaders too...maybe your local AC dealer or whatever the company name is these days,would have kits.
 
JD Mike, I have two cylinders off of a Freeman loader on a 60, they weren't leaking when we took the loader off.If they are the same length as yours, I could seel you the pair for ?? Let me know. Rob
 
Rob, I found a set of seals from Hercules in Clearwater, FL. The people there were very friendly and helped me find exactly what I needed.

Thanks to all for the help and offers!
