Here's the breakdown:
1. Ball&Ramp; The ramp is like a teardrop. The ball sits in the deepest part. The arm moves the balls up to the narrowest part of the teardrop.
This moves the rod so many mm's against the pressure plate. So if the indents did not grow deeper, the rod did not shorten, then the throw is normal and this shows no excessive wear needing replacements of said parts.
2. Pushrod to ramp; Whereas, the adjust screw moves out towards you as the plates wear down. The screw follows the rod, meaning, the screw has to have a slight gap for parts growing as it heats up. However, the 1/4 turn out from touching the rod is more then enough growth of expansion. 1/2 turn out is making the ball climb the ramp more. The trick is to keep the balls in the deepest part of the teardrop so the rod has less distance to push the pressure plate away from the pack of plates.
3. Pressure plate design; There are two basic pressure plates. One is a flat aluminum plate that is solid in design and does not wear or move from its basic form. A wave plate however has memory. Meaning, it will concave into a cone pattern when the plates wear thin. This wave plate needs to be flat upon assembly. The way to move the plate flat is to add more steel or friction plates so the stack can push the wave flat.
4. Wave plate v. rod adjust; Notice how the concave plate has to be pushed flat so it matches a non-waved pressure plate. The ramp took up all the length of trying to make the wave be flat. Therefore, the plates are never separated because the wave is still not flat, and this now drags the plates so as it creeps, and/or is hard to find N... because of that drag via the wave not being flat to begin with.
5. Steel&Friction Memory; The steels are stamped out and have a cut edge to them from the sheering. If you want to see memory at play, the assembly is to run the plates with the cut side facing you. In other words, find the cut side and have each plate installed with the cut side stacking up as one memory movement. For example: Lay your hand over the other hand. Note all fingers move in the same direction. Face one hand against the other as if praying you understand this post. Notice how the fingers fight each other. So when you pull the clutch lever in, the plates relax and this memory either breaks free being stacked one way [is the cut side], or you see how just throwing plates in any direction, your fingers are pressed against each other and cause drag finding N this way as well.
Conclusion:
A. Stack the plates so they have the same direction upon assembly.
B. Have the wave plate remain flat so the plates are stacked to cause this wave to be assembled flat when the pack is assembled.
C. The screw turn is 1/4 out from the balls being in the deepest part of the ramp, the rod is set back the farthest at the arm.
