H Clutch Update Question

Spent all day under the "H". No closer to solving the clutch-pedal-travel-distance problem.
[Side rod alongside the "H" was barely threaded into the pedal bracket, barely holding on by one thread. It worked OK and all, but no adjustment left.]
Here's where I am;
Clutch disc; Mine measures 0.310" across, the Case dealer's re-man one measures 0.350". Can't tell the difference. Gotta believe mine is OK.
Pressure Plate; My three finger ends have lots of metal left, the re-man plate at Case has very worn fingers, and has been ground down. I have 3/16" of metal left on the business end of the plate, the re-man one has been machined down to a whole lot less. Gotta believe mine is OK.
Release bearing; Mine measures identical to the new Case-CNH one. Side-by-side absolutely no difference, except mine runs buttery smooth.
Adjustment; I got a copy of the IH clutch adjustment manual, and thought I'd found the problem; the manual says to adjust the fingers so there's 2 5/32" of height from the finger tips down to level with the plate. Mine had 2 13/16", I thought AH-HAH, way too tall. Adjusted it to that, reassembled the thing, and it's much worse. It has gotta be readjusted back up to 2 13/16 or so.
OK, guys, I'm at a loss. Got any bright ideas?
 
If it is still apart, measure from the pressure plate mounting surface to the friction surface of the flywheel. this distance is critical. If the mounting surface was turnd down more than the friction surface, it will cause the fingers to be way in and the adjustment maxed out.
Also if the fork to rod fastners are bent or worn it will allow the outside lever, to move much farther than it should.
Remember a worn disk will make the rod need to be shorter, the opposite of what is happening. Jim
 
It may be possible the clutch rod ( holding by one thread) is from another tractor, measure the length.
1. Check clutch release fork (over the throw out bearing) it's either bent, or not tight on the clutch shaft.
2. Check keyways on both sides of clutch release fork that are in the shaft for slop.
3. Check the clutch release "pins" on both sides that engage slots in clutch release fork for excessive wear.
You are getting some serious slop somewhere, I would almost bet the release fork is loose on the shaft.
 
Before you check the lever height of 2 5/32" you have to make sure the cover height is held to 27/32". That is why adjusting the lever height with the clutch installed is just a guess.

At this point, since you have already disturbed the lever adjustment, I would just adjust the levers until they are parallel with the flywheel and make sure the release bearing contacts all three levers simultaneously. If you want the adjustment threaded in more than that, move the lever height a little more to the rear.
 
Guys - Thanks, I"m gonna tear this thing apart one more time, getting good at it. Owen, I"m not sure what you mean by the cover height of 27/32". What should I be measuring??
RHT, thanks, I"m gonna check everything more closely.
Jim, thanks, what should the distance be from the mounting surface to the plate surface? I"m trying to remember, if I can figuer a way to adjust ths.
Rusted, yep, you might have the best idea. I sure thought about it.
 
10 minutes later - I see in the manual what you're talking about. This thing is coming apart one more time,this weekend. Will let you know. I really appreciate it, guys,thaks a lot.
 
As long as you are going to take it apart again you should check to make sure the step in the flywheel is 1.188".
 
(quoted from post at 03:36:23 08/02/13) Havemn't done anything with the flywheel. Is it easy to get out??

If it is anything like an M (and most H things are) it is 4 bolts and really heavy. Not a big deal.
