Oil Seal for Hyd. Pump - Early Style

Postby AL Farmall Boy » Mon Jan 28, 2013 3:11 pm

Did a couple rebuilds this weekend on some Cub Hydraulic Pumps. One of which is the early style with the actual oil seal instead of the o-ring. Upon cleaning up the outside of the pump I noticed that under the red paint, it had Federal Yellow on it too. I thought the pumps with the oil seals were early pumps (late 40's - early 50's)??

2nd Question......I looked at TM Tractors site since the oil seal wasn't included with their rebuild kit; but didn't see that it was offered on their site. I've also tried searching the part number off the old seal on a couple parts stores sites, but no help. Where would I find the correct seal for the pump. Here is the old seal that came out......

And here are some pictures of the entire assembly as I took it apart and discovered it was the oil seal type. I decided to not go any further until I got the correct seal and could finish it.

Thanks much! The National should suffice to get a parts store to look it up.

The nice thing about that seal is that it is quite a bit thinner than the original, so you can install it shallower so the lip does not ride in the shaft groove cut by the old one.

Yes, I was reading in your older posts where you had mentioned that. That is a good thing. This particular shaft isn't as worn as the shaft was that had the "o-ring" style seal. The shaft that had the o-ring seal had a groove cut in it and was a little rough, so I smoothed it down with some 600 grit paper. Hopefully it will be fine, as everything is good and tight after putting it back together. This particular pump wasn't in as bad of shape. It only had a small indenture where the seal lip was riding and wasn't rough at all. All-in-all, it should be like a new pump once I'm done with it.

Thanks again for the help and information guys! I think I'm gonna tackle a rebuild of the touch control next, as well as each for a Farmall 140!! (fingers crossed)
