1977 d200 clutch problem

I've have just replaced the clutch in a 77 D200 full time four wheel drive. The problem now is in order to get the clutch to release I have to get the through out bearing up tight. when I looked at the disk as the clutch was released the disk appears to be expanding (getting wider). What happing here? was it a cheap clutch and I've popped the rivits? I know the throughout bearing will wear out soon the way I have it adjusted. Any thoughts?

thanks

if you had popped the rivets the clutch material would have come untogether in a big hurry. what shape is the bushing in the clutch pedal assy in ? a bad bushing can cause to be in capable of having enough throw to fully disengage the clutch. just throwing some ideas out there
