2072 leaking around drive shaft
 

As the title says my 2072 is leaking around the drive shaft where it enters the transmission. I have seen a few posts implying that the shaft gets worn resulting in the leak. Is this correct? If so how is the best way to attack this? If not is there a seal that can be replaced or what? I am in a bad way here and need to get the ol girl back to work. Is there a temporary solution like using some lucas stop leak or something like that? Any information or guidance is greatly appreciated.

ive never touched that model tractor but i can tell you that until you tear it apart you wont know if the shaft is worn or if the seal just went bad. as far as an easy fix goes you may be able to use a speedi sleeve if you can find on the proper size.

Thanks for the advice. I guess I should have asked for direction on how to get into it or if there is a manual or a write up to refer to.

There is a seal yes. It's not too bad to replace. Yes there is a manual, it's in our tech section. You can find it here. Page 3-49 is where the section starts to show how to replace the seal.

Excellent thanks for the direction fellas.

This seems to be a stupid question on my behalf but what how do I know if it's model 682, 782 or 982? There are different directions for the different models.

You said it was a model 2072. :Huh: So, it IS NOT a 682, 782, or a 982....

I have no idea where you are getting that info. Go to the page in the book that I linked you too. It is for the 2072. I gave this info in post #5.

There is nothing to changing it and I think they are all the same. Just make sure that you mark the housing so you put it on the same way. Pull the drive shaft off, the two bolts and drive the old one out. The new seal is a NAPA 6204 or a National 471466. I think the seal is only about $5 so I would try a new one first before you try any repairs to the shaft. Now is a good time to check your drive shaft for worn parts. That maybe what caused the seal to fail. Good luck!

Years ago my 1572 started leaking at the seal intermittently. It would be fine for a mowing or two then start leaking again. I simply took the old seal out and replaced it with not problems, but the leak continued. As I dug into it further, I found that the pump shaft had worn in an egg-shaped fashion right at the first internal bearing. I suspect it was from the drive-line clutch running in an off-center condition due to a worn bronze drive shaft bearing that I had replace the year before. One thing leads to another.
