1952 SC and outer axle seals

62champ · Mar 6, 2011

After almost 60 years on use and Texas heat the outer axle seals on my Super C are pretty much just a memory.

Question is about necessity - what would not get lubricated if the rear end oil level was at the bottom of the axles? Tractor does not have a pulley and the PTO will never be used.

I have the paper seals for the caps on the end of the axles but would have to buy the seals themselves - is it as simple as removing wheels and axle cap an then removing seal or am I trying to simplify things too much?

There is not supposed to be oil in the axle housing. The inner seal keeps that out, the outer bearing/seal is lubricated by grease. You should be able to remove the seals without removing the axle and housing. You need the seal and a felt washer, available from CaseIH or any place that handles seals. However if there is oil in the housing, your inner seals are shot too. This means you have to remove the housing and replace large gasket and inner seal.

If you don't have a parts manual, look up Super C in the parts section of www.caseih.com.

Thatsabout how simple it is. Just a matter of handling the wheels and cast centers. Than like you said you remove the cap, take out the old seal, put new one in and put it back together. Hardest part is handling the wheel and center, helps to have two people.

Thanks - so the outer oil seal is simply to keep grease in the bearing and dirt out...the additional lubrication from the rear is not necessary...

Guess this job is getting bigger and bigger...then again, I could just keep topping things off as well :?

I replaced just the outer seal and felt several years ago on my 53
SC. I later learned that there was and inner seal and it had failed.

I keep thinking that someday i'll tear it down and do it "right". It
does not leak oil so I'm not too motivated.

What's the down side of not replacing the inner seals?

I have done the seals both ways. On the tractor I restored, the axels had been cut with a torch so it would fit through the gates. When I replaced the axels I replaced both the inner and outer seals, both had deep grooves. On the inner the seal can be moved to run on a new surface. Not so on the outer. Looked to far to push a sleeve so I built it up with JB weld. So far so good. On the tractor I use (not pretty at all ) I took the short cut and just replaced the outer. Had to add more oil but so far it seems to be holding (two years now). The gaskets and bolts on the housing are seeping but no major leaks.

Thanks - I am kind of leaning in this direction. If anything, the outer bearings will get a little additional lube from the rear and the seals at the housing to main case will not have an excuse to start leaking because I did not seal everything quite right getting them back together.
