HARRY - Yes, clutches are one of those things you should, "Do as I SAY and DO NOW, NOT as I DID!" ;-) Everything you need to know about proper care & use of a CC clutches is in the CC Operator's manual. Keep them adjusted, don't ride the clutch, only put your foot on the pedal when you need to stop or change directions. IH took care of everything else... except putting the correct orientation of the anti-rattle springs on the service manual.
On the anti-rattle spings, when installed per the manual, the ends that go over the OD of the friction disk have very little force. When you install the springs on the roll pins first, then slide the friction disk onto the roll pins, you trap the springs, yes, but the ends also have a LOT more force so they resist centrifugal force and don't unhook themselves from the friction disk. Installed per the manual, they come off in meer seconds. BT-DT.
Still not agreeing on the T/O bearing wearing the drive shaft. Yes, the bearing moves up & down the shaft... sliding what? Maybe a half inch? The inner race should ALWYS be turning with the driveshaft. The whole T/O bearing will be turning, so for a brief instant when you push the clutch pedal down the outer shield over the bearing will be rotating when it contacts the T/O lever. But if your T/O bearing is good, the outer shield should stop instantly and no wear occurs after that. Yhat's why they use a T/O BEARING in the first place! CC clutch is no different than ANY other clutch in that manner.
I don't think the newer T/O bearings your local CC dealer sells are as good as they were decades ago. I know where there's a mountain of T/O bearings made by IH's original supplier that I'm going to use when I replace the teaser spring in my 72 this winter. I don't think I replaced the teaser spring 3-4 yrs ago when I went back to the stock clutch, maybe I did, but it's broke... clutch is "grabby", so I get to repair it again! Only takes an hour or two.
Well, I've got 2-3 inches of snow to clean off the driveway, then off to work! Not using a CC to push snow, but's it's IH and a GD! ;-)
