Leaking Axles

On my 100 there is a lot of oil leaking onto the ground and onto the inside of the rear wheels. Obviously, I need to replace some oil seals, right? So which seal? I can't really tell where the oil is coming from.
 
CaseIH has online parts books where you can review your tractor's various assemblies and figure out what you need to replace.

First thing to do though is check your fluid level in the transmission and rear end. The "full" level isn't even high enough to reach the seals, let alone leak out.

If you're getting lots of oil out of the transmission area it is way overfull for some reason. Could be half full of water. When I changed the oil in my Super A the first time quite a bit of water came out before oil started to flow.
 
is the leak coming from the axles or the diff shaft they can all be replaced just take it apart then take old seal to NAPA they will get new ones for you
 
Even though I finished the rebuild several years ago I just started using it last year. That's when the leaking started which I thought was odd.
 
I'm going to check the levels. It's been mostly stored out of the weather but I don't want to change the seals if that's not the problem.
 
Did you only rebuild the engine? If you rebuilt the whole tractor including the rear end something must have been assembled incorrectly. I second the checking for a bad bearing and looking at the online parts break down to determine the cause.

Even if stored out of the weather, temperature changes will cause condensation and over time you can have an overfull transmission.
 
If stored in the weather you very likely have water in the transmission. The shifter will allow a little water in each rain event. When the units were used regularly the heat would drive the water off. Remove the drain plug and drain off the water. If the oil looks bad you need to drain and replace.

You need to remember that the old units did not have the best designed oil seals like you will see in modern units. Many implement bearings had no seal at all and the grease had to be replaced daily or more often than that. Some heavy equipment still has no sealed bearings. Even so the seals in your axles and wheels were not designed or intended to hold oil levels above the seal. Waste grease will build up unless you keep it cleaned and wiped down.
