Oil Leaking at Bell Housing

I had my 1950 TO-20 out this past weekend using my scraper blade to remove snow (8" in Delaware).
I notice oil dripping out of the bell housing at a pretty good rate. Would this be the rear main seal and if so, does the tractor have to be torn down to fix? My motor uses no oil and does not smoke so I would hate to break it down to fix this leak. Any suggestions?
Thanks!

Craig

I had the same problem last year while plowing snow with my TEA20. Started with a few drips, turned into a small torrent! If the oil is clean it is trani/gear oil, if its dirty and black its engine oil. I parked my tractor, ordered two rear main seals and two trani input seals (two of each in case I ruined one during installation), and an oil pan gasket set. I had a good used clutch that I had purchased earlier on spec, you never know when you might need one you know... Anyways drove tractor into garage at about 10am and she was out running by 10pm. Rear main was the culprit in my case. While apart I changed rear main seal, trani input seal, inspected trani shifter rail plugs as oil WILL leak out of those little devils, installed new clutch, and of course an engine oil change! She worked like a charm!!

Do the work now and you'll never be sorry that you did it!

Cheers! and Good luck!!

Thanks for the info! Looks like I will have to split the tractor. I put a new clutch in about 5 years ago, so hopefully it is OK.
Time to order some seals!
Thanks again!

It could either be the rear main oil seal or the input shaft seal on the transmission. Either way it's a split the tractor to fix it job. I have heard of people replacing the rear main from underneath by just dropping the sump and feeding the new seal through, and then using Loc-tite to stick the ends together. Don't know if this is successful or not.

If you ignore the drips, eventually your clutch will get oil soaked, and cease to function.

If you're going to do the job properly, while you have it split, do all the seals you can get at, and the clutch pilot and thrust bearings, and a new clutch (the old one will be covered in oil anyway even if it isn't worn). That way you won't have to split it again in 6 months time.

See previous postings on splitting tractors before you start.

Good luck.
