MF 135 leaking oil from underneath where the cotter pin is

[Saikbran]

I think my 135 is either leaking hydraulic fluid or oil or maybe both.

Is there anything I can do to slow down or stop the leak with out spending $1000’s

Are the seals easy to change?

Probably the rear main seal is leaking, you'll have to split it to find out

Whatever you do don't attempt to plug the hole.

Hello Sa.. welcome to YT! If you can work on it yourself it probably won’t cost that much. If you have to have someone do it for you it will be close to that. There is nothing that can be done to slow it down. Are the seals easy to change?.. That is a somewhat relative question. Splitting a tractor is not the easiest job, so there is some degree of difficulty. If you haven’t done much mechanical work, getting the seals in properly without damaging them also has some amount of finesse.
