1864 puking oil at the PTO - HELP!
 

Hi All,

Got really lucky yesterday. Just got done finishing the lawn when I noticed a huge oil stain on my deck... shut her down and there is oil just puking out of the front PTO shaft...the engine should be fine, thank god.

So... I have taken this apart...

I'm just not confident enough to assess the damage...

Does anyone have a parts breakdown or schematic for this? I show two bearings I could possibly replace in the PTO unit itself and one seal, part# AE7782E. This appears to be the only seal that keeps the oil behind the PTO? I just don't get how that seal is enough of a barrier? The seal is toast, but I am thinking there might be something I missed - maybe another seal disintegrated?

A parts breakdown would be great. I have the Kohler Commander manual, but nothing in there or the 1864 manual can help me...

Just want to make sure I put this thing back together right.

Thanks for any help.

Cheers.

Pull the PTO off and replace the seal, Cub part # KH-24-032-01 On most of the CH18's you can actually put 2 seals in the bore, just don't push the new seal in to the bottom or you will block off the oil return hole. Helps if you remove the hood and grill to get at everything.

That's what I was thinking - there looks like there is room for something else in there. I think I'll stick with just changing this seal and see what happens...

Any ideas on why this would fail?

Common problem?

I shudder to think what would have happened if I didn't notice this and kept on mowing... yikes... expensive boat anchor, lol.

Thanks again for your help :beerchug:

Maybe excessive blow by or a clogged breather or just old age. They do have a lot of heat up front and the heat shield directs it at the clutch and front of the engine.

you can put a new seal in over the old and you should be fine

...And then the next guy to fix it has two bad seals to remove. Why not just take an extra 5 minutes to do it right and remove the old seal?

excuse me i am sorry for sugesting putting a new seal over the old, it has nothing to do with doing it the wrong way but there is plenty of room for 2 seals, and most people or at least i use 2 seals, please do not think i would do anything to make it harder for the next guy, sorry for the suggesting of doing it the wrong way,
