Ended with 92 GBP, the other one ended with 67 GBP....

What might one of our complete working unit  be worth?

With the parts we ordered to make them we sadly have one unit too much.

This TR3 clutch I got borrowed from a friend for a closer look, weight is 7.3 kg

On the fingers I realize where the release bearing touches them

Closer look on the Sachs release bearing - I guess this will not work.

You can always have the TR3/4 flywheel drilled and tapped to accept the diaphragm clutch

like this.

Yes. 

I cant claim the expertise of doing  it. I had it drilled by someone who has a template for the threaded holes and the dowl / peg holes.

I wonder how accurate you can get the centering holes (and what is originally achieved, Even if only  a bit off, it would have significant effect on vibrations. But if you would balance the whole assembly (minus the driven plate) that would not matter.

Bob already told at another post the new clutch could already be the template....

I guess the most accurate drills only must be the two centering pins to get the unit in the correct position.

For a mechanic this should be a solvable challenge.

FWIW The release bearing is different for a spring clutch (TR2/3/3a/4) to a diaphragm clutch  (TR4a/5/6)

Hi,

I guess I will fit mine in Dezember or January on the car, so it is time for some other projects (already started).
