Clutch fork question

There ya go, you found the problem, shine a light in there now and see what's wrong.
It's beem 35years or more since I worked on those NP435s, so I might nor remember this exactly right, but here goes;
From what I remember that NP435 does NOT have a 1x23 input but rather something much bigger. And that will require a bigger, matching TO bearing, and a matching TO fork.
If you have a lot of vertical play on the outboard end, then;
if the fork pivot is a ball, that's NOT right.
But if the fork pivot is NOT ball, then some play, on the pivot bracket is normal. But when you push the TO bearing onto the clutch fingers, using the fork, the Fork will stop floating and drop into the pivot saddle, and at that time, if everything is matched, you should have little to no vertical play on the bracket and so, the same on the outboard end

I have never messed with a hydraulic clutch, so one thing that concerns me is this; how is the freeplay set and maintained, to keep the TO bearing OFF the fingers? Cuz if the TO bearing is full-time spinning, it will not last long. I have seen the nylon ball-spiders overheat and come apart.
