4030 clutch won't disengage

[Whitedog]

My guess is one or both traction clutch plates were damaged while joining tractor 1/2's back together. Were tractor 1/2's parallel with each other when rejoining together? I also suggest to check clutch operating hyd pressure.

I just had a thought about something I didn't understand. After I got everything back from deere, they left the clutch bolted to the flywheel. I compressed the fingers and shimmed them in position with washers before removing the clutch. When I installed the clutch back onto the flywheel, I tightened the six bolts and the fingers were way tighter than when I removed it. Is this normal, or an indication of something wrong?

Sorry but It's been too many years since I witnessed a tractor with Perma-clutch apart to correctly answer your question. I was thinking clutch fingers were loose enough when PP was bolted to flywheel to rattle but I could be wrong.

If the fingers are tight,the clutch is engaged.You need to find a permaclutch installation tool to set the fingers after installation.

Sorry, it was late and I missed a key detail. After removing the washers, the fingers were loose. But when I went to remove the washers, the fingers were much tighter than when I installed them. I had to push much harder on the fingers to get the washers out than I did when installing them.

We have this split and can find ZERO damage. Nothing with the pilot bearing, nothing in the splines. The only thing we see is that two fingers have right at 1/4 inch of freeplay and one has zero. The old guy at Deere said that this is typical, but it sure doesn't seem right.

The clutch and flywheel were taken to deere and adjusted with the tool. When I picked it up, the clutch was still bolted to the flywheel. I pushed the fingers down hard and shimmed them in place before removing the clutch from the flywheel. I then lay the clutch down with the hubs hanging free.

With the tractor split, one finger has zero freeplay and two of them have about 1/4 inch. The guy at deere said this is typical.

Look inside the hub should be straight and you should be able to move it around. With one finger tight makes me think it dropped a disc.

All four disc's are on their hubs. Two on the traction hub, two on the PTO hub.

Also, it had one finger tight when it came back from deere.

But with it on the tractor can you move the hub around.

Ignore this post.

With it mounted to the flywheel and the tractor split, i can move the hubs. I can spin them and i can move them up and down a bit. They are free.

I didn't reply directly to you earlier, but I want to make sure that you know that I did reply to you.

Did you ever get it in gear to see how much it was dragging. This is a long shot but maybe they didn't have the tool setup wright and the clutch is parshily engaging just enough for some dragging.

We jumped on this and measured everything we could satisfy ourselves that when the T/O bearing is back, it wasn't engaging the forks too far. We measured to be sure that the clutch shaft wasn't pushing on the hex shaft adapter. I'm sure that there was more that we measured, but we knew it wasn't anything there, so the only thing we could conclude was that the pilot bushing was too small. We did our best to measure it against the pilot and decided it was too small. We shimmed the fingers, removed the clutch, removed tge flywheel and went to install it on the pilot, but it would not go. I could look in through the hex hole and could see that the pilot was not through the bushing. We honed the bushing until it would slide all the through the bushing.



It is now joined and ready to assemble.



Cross your fingers.

I did not get it into gear. I just posted with what we found and I believe that if i had forced it into gear, it would have either broke loose and ran fine, or galled the pilot to the bushing so bad, it would have needed a new shaft.

It works now.

TLDR: the pilot bushing was too tight.
