John Deere 2010 PTO clutch adjustment

lswartz · Aug 10, 2016

I was brush hogging today and the PTO clutch appears to be slipping while mowing thicker grass bugging the Tractor Down I understand that there is an adjustment for the clutch could someone please tell me where it is and how would I adjust it. I'm hoping the clutch isn't ruined I would like to try to adjust it before proceeding further

That is a conundrum. Adjusting that was one of the last things I did 30 years ago before "retiring" from working as a mechanic. The I&T service manuals we had were worthless when it came to working on the 2010. You need JD service information.

Your only hope is to adjust the linkage in photo to put more pressure on pto clutch pressure plate fingers

Someone correct me if I am wrong. I have rebuilt the PTO on a couple of different 2010's over the years. The only adjustment there is, is to engage and disengage the PTO.

There is no linkage that applies pressure to the fingers on the pressure plate. The pressure plate in the PTO is the same concept as the pressure plate that is in the clutch.

I would guess that the springs in the pressure plate are weak or the bolts that hold the pressure plate onto the drive hub have backed out a little allowing less pressure to be allied to the friction / drive discs.

I have a hard time believing that the friction plates are worn out as they are always engaged whether the PTO is engaged or disengaged. The only time that the friction plates are disengaged is for a split second while engaging and disengaging the PTO.

I have no access to a 2010 tech manual but I think pto linkage applies pressure to a brg that when engaged puts pressure on pto pressure plate fingers to engage pto clutch while at same time engaging a shift collar. Engaging shift collar is the rattling noise linkage causes upon engagement.

If I'm incorrect please explain how you think pto clutch is engaged.

This is lswartz, the one that started this string of posts. Thanks to everone for the info, a friend of mine told me there should be a way to adjust the clutch but I don't know. What my original problem was my tractor was bogging down while I was brush hogging and back by the PTO shaft started smoking and making a whining noise, when I disengage the PTO the noise stops. He seemed to think that the clutch in the PTO was slipping. I did go back just a while ago and was able to brush hog for about 30 minutes before the noise started again. What do you think? The oil is not low could it be the crutch ? may be time for another tractor

As I recall, the operation was- as you move the lever to engage PTO, the clutch is disengaged, a shaft coupler is slid into place, and the clutch is re-engaged, all in one motion. There were adjustments you could make. The one I worked on was able to be adjusted into working condition. Original JD repair manual was necessary.

(quoted from post at 23:41:38 08/10/16) As I recall, the operation was- as you move the lever to engage PTO, the clutch is disengaged, a shaft coupler is slid into place, and the clutch is re-engaged, all in one motion. There were adjustments you could make. The one I worked on was able to be adjusted into working condition. Original JD repair manual was necessary.

You are 100% correct with the motion. When you engage the PTO it slides the throw out bearing forwards and applies pressure on the pressure plate to release the friction discs, as you continue to engage the PTO it slides the collar (item #22 in my attached picture) onto the drive shaft (item #1 on the first pic TX Jim attached) and this bonds (transfer power) the PTO clutch to the PTO pack and finally as you complete the engagement of the PTO it releases the throw out bearing removing all pressure against the pressure plate and the PTO is now engaged.

The only adjustment there is, is the timing of the engagement of the collar (item #22) and the throw out bearing.

The PTO clutch is always engaged (not the collar that attaches the clutch to the PTO pack) except for the split second that the PTO is being engaged or disengaged.

If it smoking???? and whining when the PTO in engaged (in operation), then I want to believe that the bearings in the PTO pack need to be replaced as the PTO pack only operates when your PTO lever is pushed forwards (engaged)

Is there oil in the PTO pack?

You will need a JD service manual which I have. I can scan the section and email it to you, but it will be a couple of days before I get back. My email is open.

My mistake, it is item #1 on the second picture that TX Jim attached

One of the issues with them was the roll pin hole in he lever would wear so that it would go over center before you were ready slamming it into "on"..ready or not...It is one of the craziest configurations I have ever seen,along with the 3pt linkage,,it's kinda like an erection set got thrown in there and the cover was put on...one way to correct the worn hole is to drill it over size, but this is some thing to look at as you work on it.

Correct me if I'm wrong, but if a clutch is slipping then I don't believe the engine would be bogging down. That would mean that power is in fact being transferred to the driven machine. I second the suggestions of looking for a bearing that is bad and is heating up.
