Oliver 77 row crop pto still turns after shut off?

Wes Verbal · May 10, 2015

Hello,

Have a Oliver 77 row crop tractor never had
Any trouble out of her till today? I decided to check tranny fluid to test plug out and the fluid came a pouring out down till it even out at the top of the test plug..... Didn"t change it yet but going to ...... Anyways I noticed the pto is rotating slow even after brake is set on it. And you can put your hand and stop it.... And start it by rolling it by hand again while tractor is running ??? Didn"t start this till I messed with tranny fluid ? Anyone have any clue on this matter ? Worn brake bearing or to much grease or what ????

I can't help you solve this Oilallover problem, but PLEASE keep your paws off of the PTO shaft while the engine is running!

Doesn't take the brightest bulb in the set to figure that out!

The 77 did not have a PTO brake so common for them to do that. My S88 and my 77 both will do that with out a load on them but put a load on and they only spin when engaged

Hello again ..... By no means do I grab the pto spinal-while the tractor is in motion ha...... Just only while it is on low idle and out of gear it will move even with load it acts as if it will not turn.

It has nothing to do with the oil. It's a dry clutch. You can get to the clutch pack by taking the four bolts out of the bottom of that cast housing that the lever goes through.
There are shims that adjust the clutch,but there are three little springs that go through the center plate to hold the clutch discs apart. Most likely those springs aren't quite doing their job,but the PTO on those never really did come to a complete stop very well.

Thanks much for the info..... I did take the rear cover off of the tractor and rotated the pto spinal some it rattled rough after few complete rotations?!?! That's was what I was trying to get at about this whe ordeal ? To see if the clutch might have to much oil on dics or wasn't oil enough?

If there's any oil at all,you have a bad seal.
