Pedal cluster Release spring question

[preS]

From Chassis no 305 101 (MY67) a release spring (#69) was added to the pedal cluster, for all models.

Was this an improvement/ update or did something else change in the clutch set up?

Thanks

The release bearing changed. The spring is designed to keep a constant light pressure on the bearing.

Thank you for explaining. Your knowledge always amazes me.

Yes , and there was a return spring on the clutch release bearing fork that was eliminated . Porsche wanted the clutch and brake pedals to be an even distance from the floor .

Is the bearing where the red arrow points to the earliest release bearing or is that one 356?

Thanks

Looks like a bearing for a 356 with Hausermann clutch.

Noted,

Are the 2 bearings on the right side (then) the earliest style and correct for a pedal cluster without the additional spring #69?

Richard, the two on the right are 67-69 911, 912 and all 914.
The bearing change began with the 67 S, then all models as of January 67. See page R59 in the factory workshop manual.
Your upper left bearing (red arrow) is for 356B with 180mm clutch, your lower left bearing is for 356B/C with 200mm clutch, and for all pre-67 911,912.

The 901 bearing, for pre-67 911, 912 and 356B/C models, is 23 mm from the pin center to the contact face.
The 741 bearing, for 356B models with 180 mm clutch, is 30 mm.
