6700 PTO Problem-part 2

6700. Had to replace the shaft that drives the pto from the clutch. After the tractor was put back together the pto would operate but stop after the tractor got warm. We removed the side cover to look inside. We found a broken piece that looks like a portion of a clip. See picture. Anybody got any ideas? P.S. We posted about this before on 6/23/16 under "6700 PTO Problem"...but post is to old now to allow replies.

WEll isn't that $exy. What you got there is half of a sealing ring.... most likely from the PTO. You didn't by chance 'push' her back together on the rear joint? Because it looks like you did and shoved the PTO support around and broke the sealing ring. You be splittin' her again...

Thanks for the help.....I wasn't around when it was take apart/put together....this is our first time splitting a tractor at the rear axle.....any guidance/advise/tricks anyone can share would be helpful....as we are the process of taking the tractor back apart.

also is that part you mentioned = part #81809513, Oil Seal, Split, 55.24mm ID x 60.33mm OD x 3.15mm Thk????
 
Best advise I can give you on that is to use guide bolts when you get in close for ALIGNMENT only. Don't pull it together with bolts. ALso.... place the PTO input shaft (floating shaft) into the clutch before hand, then align that to the transmission as they mate. What happens is the input shaft doesn't seat in all of the clutch plates and when you get it in close and force it together, you shove the whole clutch rearward and bust something.
I didn't go through the parts book to see if that is the correct ring but if it's the PTO sealing ring for a 6700 then I'll assume it is. A quick google search suggests to me that it is...

When I repaired the pto on my 5000 this spring I pulled the lift top and removed the bearing cover on the back.
this allowed me to work on most every part of the clutch pack and control valve without splitting the tractor.
This would be difficult to do on a cab tractor like my 6610.
 
did this 5000 have load monitor? This 6700 does.....I've got it in my head the load monitor might be in the way, but not certain.....thoughts anyone?
 
I think the others may have forgotten that ~normally~ there would not be a load monitor on the 6700. It WAS optional.... Personally if I was splitting it again I would not pull the lift cover. That's just more work in my estimation. However............. if it doesn't have a load monitor you could do the repair through the top. You would also need to pull the pump and the top link rocker and bearing retainer on the top/rear shaft. What you do then is remove the PTO control valve and the rear shaft and slide the clutch rearward. You do need to insure that the input shaft is seated properly in the clutch plates. Then you need to reset the clutch rear support/valve. I'd like to tell you this is easier.... but it's probably not. This is just a dirty miserable job no matter how you skin the cat.

Bern, Speaking of load monitor, Of all the dozens of Ford tractors in my area, I know of only one tractor,a 7000, that has load monitor. Was it a success or a total failure for Ford. None of the old timers that I have talked to ever saw the real benefit of it.Your thoughts? Please
 
All of the 7000s, 7600s, and 7700s had it as standard equipment, except the Blue Power Special 4WDs. It started becoming optional with the 10 series.

In my opinion, I think it's a good idea that works well as long as you have good traction. If you spin out in a mud hole, however, it does the exact opposite of what you want it to do.

I've only tried it out one time, on a 7710 4WD. Once I got it dialed in, I thought it was very responsive and did exactly what I wanted it to do. Being able to adjust the implement depth on the fly with the 3-point handle was an added bonus.

I've also used Load Monitor once on a 7600 as a remote outlet for a single-acting cylinder because the tractor only had one remote valve and I needed two. Again, being able to adjust the implement height with the 3-point handle was way cool.

I think the biggest "problem" with Load Monitor is that most people had no idea how it worked, and the whole "hooking up the remote cylinder in series with the lift cylinder" concept confused most people beyond their desire to use it. I suspect Ford finally realized this as they were getting ready to introduce the 10 series tractors, and decided to make it an option instead of being standard on the 7610-7710s.
 
I think 'nifty' about covers it. It was a fancy idea that in practice was just a pain to get set up and had minimal benefit to start with. It wasn't the fanciest thing to work with using a semi mount plow either. Using a remote to control the rear lift made it a lot easier to drop the plow square in the cut than having it drop all at once...
The constant erratic reaction of the arms when unladen is beyond annoying...

"The constant erratic reaction of the arms when unladen is beyond annoying..."

Do you mean when you're not using the Load Monitor? If so, the arms should not move any more so than a tractor without it, if you have the selector lever in position control. Whenever someone called me with a complaint like that (for example: "The arms go up when I let the clutch out"), I always had them move the lever back to position control. That usually cured it. In the rare case it didn't, it required an internal adjustment to the linkage.
 
That's exactly what I'm talking about.... but the little I used it, that was the normal go ahead when you were maneuvering around, etc. So the easy solution was to put the system back and position control and get on with life. The system didn't really endear itself very much when you go to raise the plow at the end of the field, the load comes off and it drops the damn thing again... It probably wasn't adjusted correctly.... but that's what it was.
