Oil Leak

[Roy (NC)]

Discovered a small puddle of oil under my 8N after it sat in the shop today. Until now it hasn't leaked oil.

When I checked to see where it was coming from, I discovered a hole with a cotter pin in it. The cotter pin was put through the hole from inside the pan, and bent out. Oil was dripping from it.

I looked in my parts manual (pg 73) at the engine breakdown, and it shows this cotter pin. Part 72038S.

What is this for and why is it all of a sudden leaking?

I could probably stop it with some JB Weld, but I don't want to do that if it has a purpose.

Thanks,

Roy

Don't remove cottor pin and don't stop up th hole. It is there to let oil drain out of the bell housing. The oil is either coming from a bad trans input seal or the rear main engine seal. The cottor pin keeps dirt from plugging up the hole. It need to drain out or you clutch disk will get fouled up with oil.

Don"t plug the hole. It"s there to allow any oil leaking, usually from the rear engine seal to have somewhere to go. The cotter pin is to keep the hole from plugging. It"s doing what it"s supposed to do. Watch the leak and if it doesn"t get to bad I wouldn"t worry about it. Just keep your engine oil at the proper level.

It is supposed to be there to prevent your clutch housing from filling up with oil in the event of a leak.

The cotter pin is there to keep the hole from getting stopped up.

JB Weld there is a no, no.

Your mission, should you decide to accept it, is to figger out ifn it is engine oil, or rear end oil.

If engine oil, just put a bucket under it and keep your engine oil checked.

If rear end oil, it is probably a bad front tranny seal, and it will be leaking on the clutch, and eventually it will start sticking, and you will have to do the dreaded split, and fix it.

Thanks guys for the input.

Today, I jacked up the rear end so I could mask and spray paint the rear wheels.

It sat this way most of the day. Maybe all the oil ran to the front and came out this hole.

It's back on the level now. I put a container under it and I'll check in the morning to see how much, if any, leaked out.

Learn something new every day.

Thats was Henry Fords way of keeping the oil drain plug open. Its there to drain oil form either the rear main or the transmission out of the clutch housing so as to keep the clutch sort of free of oil. So NO DO NOT PLUG IT, r you will have real problems down the road. It was a low tech way to keep a problem from being a big problem

Your front tranny seal is gone.

Time to replace it fore it swells yer clutch plate up.

It will sooner er later.

As the rest said, except is is not necessarily a tranny seal, you dont find too many dry cotterkeys and drain holes. Dont get too excited. More than likely you just moved some drainage when you jacked up the tractor.

Well, I didn"t know sooner. Another "old timer" told me last year to clip them off and set screws in them. Now what do I do?
Thanks

Open it up, and let it drain, ever month or two, or three, or whenever you think about it, run a wire up in it and make sure it is open.
