Yes please take pictures Paul, and if you happen to find anything that identifies who made the loader please let us know. I would like to see some pics on how yours is setup also.


Could it be that they were manufactured by International? On tractordata.com they mention a loader type "International 100" http://www.tractordata.com/farm-tractors/004/6/8/4686-farmall-cub-attachments.html
Also, mine has Farmall Cub decals on the cylinders that look as old as the rest of the rig.


The loader that IH sold was a International 1000 one arm loader:

As for the cub decals, not sure why they are on the cylinders maybe there are some other identifying marks somewhere.

Have you tried tightening the nut at the top of the cylinder? Tightening the nut may decrease or stop the fluid loss.


I have not tried that, but it looks like the previous owner tried. The nut is pretty well chewed up.

Thanks, at least I know that now.
When I first started tractor shopping I saw a Cub with one of those one-arm loaders for $2,200. I wish I jumped on it, but at the time I wasn't sure what I wanted.

I finally got to a point in my week when I could work on this thing. I guess it was more important to help my brother replace a roof, then fix the heating system in my truck before working on the Cub. :)
Anyway, I was able to take the ram apart easily by just sticking it back on the Cub, and turning the end of the cylinder with an 18" pipe wrench. The stop at the end of the piston was a breeze too. you can see in the picture of the gland that there are only three seals to the entire thing, and I can't imagine that they would be hard to find. Right now I'm thinking : "Not such a much after all".

I went to a local hydraulic place, (K&M Hose in Woburn, Mass), and I got my seals plus two pairs of work gloves for $21.00. I went home, put the seals in, and they work with no leaks. Evidently there is still some air in the system because the movement is jerky. I'm hoping that this will correct itself after some time. These cylinders were easy to work on because they are simple, single action cylinders.

Paul it's hard to tell from your pictures (I am 1/2 blind), are your cylinders and end cap the same as mine pictured below?

Yes, Scott they are the same thing. Also, there is no manufacturer mark anywhere that I could see. Are you thinking of replacing your seals?

That's Great Paul, I am thinking about replacing the seals as it has been sitting idle for 3 years while I was going through some health problems. After the winter if my health holds out I want to get the 53 running and checkout the loader. I may work on it during the winter depending on how I feel.

I had the same problem after putting seals in my Wagner cylinders. I finally took the pins out and stood the cylinder on end with the hoses disconnected at the valve so the air would migrate out the top, then used a funnel to slowly refill the cylinders and hose then reconnected the hose then mounted the cylinders. In just a couple uses after that all was good. Don't forget to regularly check your reservoir for a while or you may be recirculating the air

Scott, I certainly hope your health improves, and that is more important than any tractor. If you are in a position to work on the cylinders, I'm glad to offer any help I can via this site. However, It is a pretty simple process. One thing I would do differently is to install a 1/4"npt barb onto the cylinder as soon as the hose is removed. Put a piece of 1/4" fuel line on the barb, and direct the fuel line into a container to catch any oil that comes spurting out when you compress the cylinder.

All I needed was a 18" pipe wrench to remove the end cap on mine, and I didn't even need a "cheater". Remove the guide from the opposite end of the shaft with a 3/4" wrench, then slide the piston off of the shaft. Pick the old seals out, find some new ones, clean & oil the piston, then put the new seals in place. The hardest part is getting the piston back on the shaft. It takes a bit of pressure. Be sure to inspect the chamfer on the end of the shaft because mine was a bit rough. This could tear up the new wiper seal if you don't file it smooth. I oiled everything with hydraulic oil before reassembly. If you are in need of seals, I can probably help you out through K&M.

Oh, and don't forget to put the threaded end cap on the shaft before you put the piston back on. SOME guys forget to do that, and have to start over again. :oops:

Thanks John, that sounds like a good approach. Mine did get better today after some work in the back yard. It is a lot smoother, but still rather slow. This is probably just the nature of the beast, and I don't expect it to be as fast, or powerful as other equipment I have run. I have been checking the fluid level, and it is good.

Today I used the loader and the grader to make a spot where I will put a portable garage. It took some time, but I had fun.

The cub hydraulic pump is only 2.8 gpm, so it takes a while for it to fill those cylinders.
