I just pulled the release bearing shaft that slides the release bearing in to the presure plate. That slides around the clutch or transmission spline. There was no diagram of any coupling around that hub. The hub has a bolt with a lock nut on it that keeps the hub bearing shaft in a key way. I don't see any coupling any where. Except for on the transmission spline back in the clutch housing we discussed.
I got the release bearing out and working free greased up and back in, Got the new clutch bearing pressure plate, Cleaning things up getting ready to put everything back together. Be a week or so, I'm not devoting all my free time to it, Just making sure everything is right. I also have a hydrolic fluid leak on the 3 point lift adjustment cylinder head, Have ever pulled one of those?
