First time refitting the plate pack. The OEM pack was 50.88mm total and the Barnett pack is 51.03mm. Obviously, all the plates must be used. The depth of the inner driven hub is just over 45mm, consequently, the last driven plate and the last driver plate do not fit on the hub. What's the trick for getting the pressure plate to spin into place? Without the last two plates, I can see the proper position of the PP as it slides into and over the center of the hub as the plates wear. It appears that all the plates must fit onto the hub or the pp will not seat properly? I have pics of the assenbly before I took it apart so I know how the PP should fit. What am I missing here? The inner hub is only 45mm and the plate pack is 51mm, this is where I'm confused. I have the service manual and there is nothing about this in there, as if all the plates should fit on the inner hub.
