super m pressure plate fingers

Last fall my hubby split the tractor because it seemed to be stuck in gear. Turned out it was just the shifter stuck, we got a Sloppy Shifter kit from ebay which fixed it. Thanks to those of you that suggested it!

SO...DH figured as long as he had the tractor split, why not put a new clutch disk in...although the old one worked fine and was less than 1/2 worn.

Now, when it is back together the fingers barely touch the throw-out bearing, and do not depress at all, and he says it is adjusted according to the info in the manual and here, plus the clutch rod is adjusted as far as it will go. However, he NOW thinks he did the measurements without the pressure plate being compressed. Would this be the problem?

What size are the bolts that screw into the 3 bolt holes to compress the pressure plate? On ours the 3 holes are smaller than the 6 bolts that mount the pressure plate.

Also, the pressure plate fingers are worn into ovals at the pins where they pivot.

So, do we need to buy a whole new pressure plate or is it possible to just buy new fingers and pins?

I just want to add, we aren't mechanics, as you can tell from my post, and please forgive if I sound pretty stupid about this....

Your Pressure plate is toast. As the driven disk wears, the fingers moove further and further toward the throwout bearing. This allows a wearing set of finger pivot holes to still be usable (they wear in the opposite direction). A new driven disk puts the fingers (on their oval pivots) out of reach of the throwout bearing. There was a time one could get PP rebuild kits. someone may have them, but it is effort ahead to buy a rebuilt or new PP. Jim

Odd that it would "be toast" now since it was working fine till we split the tractor?

We experienced zero clutch problems when running it. You would think it would have slipped or something...

So, no way of just replacing fingers?

did you have the pressure plate or flywheel faced ?

They can be replaced if you find them. If they are very good, they are likely in a good plate. They could be welded up and remachined (with fixtures to assure uniformity)and the worn pins replaced.
Unless you have that skill, or determination to use the old one, I would just bite the bullet. Wear can and does happen inopposite directions in the clutch system. as it does it makes a formerly usable part (though worn) impossible to use due to the geometry. Jim

Clutch disk in backwards?

If you have a disk with a grease slinger, that side has to go toward the flywheel. If you install them backwards the cast plate of the pressure plate assembly will hit on the slinger instead of the disk facing. That will cause the levers to be too far forward resulting in not being able to adjust the release bearing enough to contact the bearing.

Plate in backwards???

Pretty sure not

No, just put a new clutch plate in...

So, if we put the old clutch plate back in, it ought to be ok?

The old plate was not slipping and according to a tractor place that we emailed the thickness to had plenty of life left in it...

WIll work maybe. The PP you have is not goode enough to re use. If you like putting it in and out, OK go ahead. Nothing but time invested. The issue is going to be taking the chance that the oval pivot points on the PP will fail, or become uneven. This puts into play the potential of parts flying out and components like starter drives being broken. I cannot see your plate or pivots. I can say that wear as described will put the geometry of the throwout bearing and linkage at bad angles, and is not in any way best practice. If money is the issue, and time and tractor in the field is not, put it back in. It could last a season. I believe it is not best for the tractor. a new pilot bearing, and a new throwout bearing should be installed either way. Jim

i have the same problem on my h farmall.i put a new motor in from a 350 farmall,and used my flywheel and clutch and pressure plate.and it barley touches the fingers?i worked GREAT be fore i tore it apart and clutch is almost new(i went to 5 tractor pulls).do i have to buy new clutch and pressure plate?.thanks alot for your help!

Jim, we got an email from a guy that has a new set of fingers!
I asked him if the fingers have an adjustment bolt at the ends like ours does. If these new fingers do not have the adjustment bolts, can they still be used, or are they just for another type of pressure plate?

I have not yet heard back from him...

Replacement fingers with no adjustment screws will be impossible to set correctly due to the wear on the pivot (on the cover) will be uneven. Fixed fingers would be OK if all wear was perfectly even.
The replacement fingers might not be for your particular PP. There were Auburn clutches, and Rockford clutches. And other manufacturers not original equipment that could be used if it fit.

I will put a hundred bucks on your pp being junk. If your fingers are so worn they won't adjust I could guarantee your pp is warped. That hundred bucks would buy you your pp. I just looked at my bill the other day when I did mine and it was 140 (if I was looking at the right invoice)
