Re: Problem with clutch disengaging
Just talking to myself here.
Even though the throw-out bearing turns freely and quietly under testing (standing on it and spinning), the only thing that could have caused the release fingers and the big lever to have worn where they did as a much as they did was if the bearing froze for an extended time.
If I can find three new fingers and a correct t/o bearing, I will have hope for a fix.

Re: Problem with clutch disengaging
I am having no luck finding the three release levers (fingers) that I think will put my '60 1500 back on the road and pasture.
They carry the number C-4B-200-F; the B could be an 8.
They have two holes for pivots at .475 diameter, with a weird plug in the outer one.
I am hoping someone has a pile of (or even one) pressure plates with good levers.
I don't need the plate and the levers would be easier to ship.

Re: Problem with clutch disengaging
Is this the part with the fingers you are looking for?

Re: Problem with clutch disengaging
I think the control shaft broke at the clutch pedal years ago and was carelessly welded back in the wrong position relative to the adjusting rod clamp.
A modification seems to allow both free play at the t/o bearing and proper disc release.
Details on request.
