I have a '78, '84 and '86 that use the spring because the factory specifications calls for free play in the throw of the clutch pedal.

The theory is to allow the throw out bearing to back away from the spring fingers that apply pressure to the disc.

I know they all have a piece of rubber for the cable to pivot in.

Now my '91 does away with most of that and added a large chunk of iron onto it. No play at the foot pedal, big chunk of iron?
Gets me!

I have often wondered how or why it is now OK to leave the throw out bearing to sit against it myself. The bearing and clutch are components are different but haven’t studied how the bearing doesn’t spin all the time.

Maybe someone can shed some light how this now is a good thing.

How does the newer style slightly larger diameter clutch work with less effort on the pedal yet using the same methodology overall?
