Installing a replacement dual 11 clutch kit, identical to the one I took out with one exception: The engine clutch fingers are a full one inch lower than the unit I took out. The PTO fingers are the same as my original. I expected there to be a difference in the engine clutch fingers due to the added thickness of the new clutch disc (vs the thin warn clutch disc). Yet when I put the two halves of the tractor back together, my clutch pedal's full range of motion (to the floor) still would not yet even touch the fingers, much less depress the clutch.
I spoke directly with the engineer at Hy-Capacity clutches, who concluded that I had the correct part and the fingers, set low as they were, are to spec. However, he said, if my flywheel had been resurfaced, I would then have to break the QC seal on the finger locks and raise them to meet my circumstances.
I bought this tractor with 1500 hours. It now has 3000 hours. The clutch I took out was stamped with CNH. I still have what I believe to be the .020 factory step on the flywheel. All of this leads me to believe that I am the first to split this tractor. Even if I'm not, I'm still sitting here with a clutch pedal which cannot reach the fingers.
I've retorqued the clutch back onto the flywheel to obtain exact current finger heights. I've made exact measurements of where the throw out bearing is positioned at pedal spec (5.51 above the floor to the top center edge of the pedal). I now know that my engine clutch fingers need to be raised 5/8 in order for the pedal to engage properly. But now here is my new question:
The PTO bearing carrier HAS a return spring. The engine clutch bearing carrier DOES NOT. This leads me to believe that the engine clutch bearing is ALWAYS resting on the clutch fingers. In other words, the engine clutch throwout bearing is designed to ALWAYS be spinning. (?) Seems hard to believe as this is more or less riding the clutch, by design. (Okay, so it doesn't cause minor clutch slippage but it does cause the bearing to needlessly spin for every second the engine is running.)
If someone knows the answer to this question (Is the pedal bearing supposed to be parked right on the fingers when the pedal is fully released?), I will then set the fingers accordingly. I was going to set the fingers to allow about 1/16 clearance, but again, with no spring to pull the pedal back, the bearing is going to naturally fall against the fingers.
Apologies for the long story. Better to provide all the details upfront than hash it out later!

Today's Featured Article - What Oil Should I Use? - by Francis Robinson. I keep seein this question pop up over and over again in discussion groups all over the web. As with many things there are often several right answers and a few wrong ones.
