" Is this typical??"


You've got a seal failure.

Rear engine crank seal or front transmission seal.

Chances are the rear crank seal was replaced in the overhaul. And, when it was split, you should have replaced the front transmission seal.

No need to guess though; is it oil or hydraulic fluid?

Bruce, I checked the fluid that came out and have a feeling it is the engine seal. I have never taken apart an N tractor. Any basic hints for the novice that are not covered in the manual? If taken apart I want to check the oil pump too, it does not hold a decent pressure when hot. Any additional thoughts are welcome.

As others are telling you, I'd leave it be until it shows up on the dipstick. Just park it on level ground!

What kind of oil pressure do you have?

Unfortunately, a worn pump is not the usual cause of low oil pressure; it's worn bearings.

If its not a steady occurance I wouldnt get too excited yet. Mine does that once in a while when I load it on the trailer. Suspect that the angle when loading it causes some puddling to run out.

It's a good thing that your 8N leaks oil because you won't have to kill the weeds where you park it.
