Allis 7000 pto

Maybe it's normal. What kind of implement ?? Do you have the engine idled down fully ??  I'd be more concerned if it was slipping under load than what you are complaining about.

Not saying there isn't something going on, but why 1500 RPM engagement speed on the Kuhn mower?? Why not 800 ??

But, you haven't acoually tried it on the Kuhn mower, correct ?? The rake is a low HP/torque implement and the PTO clutch might be a little aggressive on it, but on the mower it may be fine. Try it before tearing the tractor apart and try it at 800 rpm.

Make sure the cable goes smooth at lower end my be tight 

No I have not tried it on the Kuhn mower yet. But I will today.  The slip clutch on the rake never makes noise when I use the Zetor. First Alvin I'll check the cable end. 

The 7000 has two drawbar length holes in the front. Difference between them is probably 3 inches center-to-center.  Short for 540 machines and long for 1000 RPM machines.  I have no idea why that implement won't connect to either tractor...strange.

Finally I got a chance to look at the 7000 that's nearby. But first I want to start with a couple days ago. My son is in the cab, and I watch him slowly bring pto in all the way. The pto turns slow, then almost stops, then spinning. But then I'm hearing bad bearing sound coming from the pto shaft at the back of the tractor.  So I walk around and tell him I'm going to the valve body for the pto. He tells me he can here that racket upon engagement, then quiet. So he engages the the pto, and I can hear that hydraulic squealing sound coming from the pto valve body. So instantly I'm thinking there's something gone bad in there. But then in the next second I'm hearing a bearing that is chucking bad, and does not sound good at all. So the sound is just traveling down the shaft. I'm thinking the squealing sound is the hydraulic oil going by the spool valve, has it tries to turn the shaft. The bearing is that bad. The other tractor makes absolutely no noise  with pto engaged. In the picture the bad bearing sound is coming from the area where the neg battery bolts on.

Interesting, because the other tractor is quiet. So that blows my theory. So is removal of pto valve body the next step.

Yes the other tractor is a late 1978 maroon 7000. Mine is a 1976 model. I never knew it made the chucking noise till I was in front of it. But the squealing noise is not heard in the other tractor, nor the chucking noise. 

You think you have a problem with "harsh" PTO clutch engagement. Quit worrying about whatever hydraulic squeal/noise you are hearing. You have two nearly identical tractors. Hook each one up to the implement you think you have a problem with and compare them for clutch engagement. I'm not there standing next to your tractor but I'm not yet convinced you have anything to worry about.

we have several 7000 's with high hours.  We are finding the aluminum valve body is being deformed where the steel spools slide all the time.  You may or may not have an issue as tractors are like motherinlaws  no two are exactly alike. I would pull the modulator valve out and check to see if the bore is perfect and not sticking the valve. If it has a ridge on it polish it out...  That is the valve removed below the inching valve. 

#29 and 33 will fall out. Make sure they go back in right places. They do crazy things if lost or in wrong places.                MACK

I got the new pto shaft installed, and mowed with it today. It does start the mower slowly, then comes right in. I'll run it like this till fall. Also the valve bank leaked so bad I had to change rags under it every time I used it for raking. I fixed that over the winter. When I was done mowing I felt around the valve bank, and it was dry as a cork leg, lol. It was such a joy to mow with a two wheel drive tractor again. And then not have to unhitch from it.  

That looks like a picture post card.
Beautiful set up.
Good work Tim! Staying with it & figuring out a problem payed off.

Thanks for the compliments guys. Fixing problems in a 45 year old tractor, are like little victories.
