oil seal

[msportbiker6666]

i have a fh680v. not sure of orig hours. gov shaft oil leaking. simple enough, right then. 30 minutes later job done. the next day I noticed it was still leaking so I replaced again and its leaking again. I made sure all the mating surfaces were clean, oiled up the seal, then slid the seal home. I've done probably 10 to 15 of these in my life and I know I'm doing it right, least I think I am. my conclusions are now it is the governor shaft arm is somehow messed up or am I doing it wrong? it actually leaks when engine is off. any help would be greatly appreciated thank you

I think that shaft may go through a bushing. Is there any slack in shaft up and down or side to side? I had that problem last year and I was asked about slack but mine didn't have any so I replaced seal and so far it has been good.

Did you damage housing when you took seal out is another thought I have..

their is only a little in/out play which I think is normal. I ordered a couple more seals. maybe I can still add shaft and if their is a bushing I will order it as well. to 'stem the tide' till ups gets here, I added an o-ring. thanks for your help

I had slack in and out I am talking up and down. If bushing has slack that means sump has to be dropped if I remember right when I done mine. But I was lucky and just had to change seals. Restorob on this forum helped me with advise when I changed mine..

I didn't check other free play directions but im sure ill get a chance soon

Did you smooth governor shaft before putting new seal on. I used a piece of fine sand paper and made shaft as smooth as possible before taking old seal out to try to keep from cutting new seal.

thats a good point. i prob. should have done that. i guess tolerances are extremely tight

ran the machine, bobcat zt223, for 5 hours yesterday and gov shaft oil seal leak all but stopped. I simply added an o-ring on top of seal. will see how long it lasts.
