TO-35 Seal Leak

I have a TO-35 that has a leak at the telltale hole in the transmission housing (double clutch). I was told it was the oil seal (Number 11, Figure 12 in the manual) and/or the rear oil seal of the engine. I think it is a combination of the two. I have a few questions. Will it ruin the clutch? Is there and other things I should do or replace why I am there? Are there any helpful hints before I get started?

Thank you for any assistance.

Brian

Brian; Maybe this goes without saying but, if you choose to use the solvents mentioned, be sure to read the warnings on the labels as these are known carcinogens. Good luck & be careful.

If its a minor leak you may get away with it for a little while. Do you have a cotter key in the weep hole? This will help keep the hole clear so it doesn't get blocked and give you a false idea of what kind leak rate you have.If you do split the tractor to fik the leak, replace all the seals you can access while your in there as well as the clutch pilot bearing, and inspect the release, a.k.a. "throwout" bearing.My MF 35 (dual clutch) was oil soaked, the engine rear main rope seal was hard as a rock. I guess once every 40 years or so isn't so bad really. The clutch isn't that expensive to rebuild so if you have to split your tractor anyway it may be wise to look at your clutch for wear. A dual Spicer rebuild (parts and labor) was $208.00. Hope this helps!

Brian,
Your leak as you mentioned could be either engine/trans or both. You didn't mention if the tractor is diesel or gas. If diesel, it would be easy to tell where the oil is from. You can also put some oil dye in the trans in order to identify. You can get it at your fuel/oil jobber. The oil does not terribly affect the operation of the clutches if they are both in good condition. I have let these leaks go for years while waiting for another excuse to pull the tractor apart and the clutches continued to function. Occaisionally the clutches might slip under very heavy loads. If you determine that the engine seal is OK, I would leave the engine seal alone when I do the job. I have had these apart and back together in a day when I had all of the parts ready. As far as what to do while you have it apart, I would replace both of the front transmission seals. You mention one but there are two. I would replace the clutch plates. I would replace the throwout bearing. I would replace the pilot bearing in the flywheel. If the surface of the flywheel is good you can leave it be but if it is gouged or rutted from worn out clutches, have the flywheel turned. If the dual clutch has been working well and the surfaces are smooth and the linkages are in good condition, leave it be. If not have it overhauled. These clutches are generally long lasting and do not wear out under normal useage. Most likely you will find that the flywheel and dual clutch are in good condition. You may also find that the clutch plates are not very worn but oil soaked. I have cleaned and re-used these before by soaking in Triclorotrifloroehtane. I have used this before in an ultrasonic cleaner and it worked great. Methyl Ethyl Keytone or MEK will also work by brushing or spraying and then working with a wire brush but do not soak. All of the seals and bearings are standard parts available at a good parts house. About four to five hours to get the tractor and clutch apart and five to six to get it together.
Good Luck, Bob
