It's those fag shoes that made that job so easy... LOL I have a massey 165 that may or may not have a PTO issue. The family farm passed to me in Nov 2022 and what if anything was going on with that tractor, except no reason to fire it up, I don't know. Dad had a larger Massey that hadn't moved in 10-15 years too, so maybe all is fine. I didn't think to ask him before he died so it will be discovery time when I get back to the farm. I hope everything is fine and I have a strong 165 to brush hog the place and clean it up some this summer. I watched a video of a guy doing similar stuff with a 165 model and it looked like a shop deal to me if it's more than that seal and bearing, splitting the tractor etc. I hope mine is easy like yours is to address if need be. Mine has a cap over the PTO shaft so I am a little worried it might be the more complex job. We'll see.

I usually face the the tractor down a heal and the fluid don't come out

Buy a pressure washer...... Use it before starting the job.
