PTO Overrun clutch

cfmarcum · May 12, 2016

I have what appears to be an unusual PTO overrun clutch on my Ford tractor. It does not have the type that has a pin that you drive through the PTO shaft where the grease fitting are. It appears to have a collar that slides back about 1/4 inch but I cannot get it to come off or even twist what appears to be a collar. I am guess that it has some sort of ball bearings that go into the groove on the PTO shaft but all the research I have done, I cannot find and overrun clutch like it. Can anyone shed some light on this. I really need to take it off and get a different type.

Thanks so much

May be a bit stuck. Yes, pull the collar back towards you but a bit more than 1/4"
You should be able to get the whole thing off the pto shaft then. I have one on my tractor, works ok. Yours may need a bit of oil or persuasion!

good soaking with wd-40 or something should free it up its just been there too long and gummed up.

I've got one, works good. Just lube it up, somehow, should come off.

What you have is the newer type of coupling. There is a very stiff spring inside it to keep it in the locked position. As there others have said get some penetrating oil inside it for lubrication. Pull the collar back and forth that releases the tension on the balls inside it. It will never separate until that collar is pulled all the way back. I have the same thing in my Woods bush hog.
