RE: Modified clutch - to be or not to be?

["Navarrette, Vance" <vance.navarrette@intel.com>]

        Don:

        I too wondered what a "hardened" roll pin was. I thought perhaps
that might have referred to a steel dowel, rather than a roll pin. The
dowel, being solid, would of course be much stronger.
        I thought roll pins were all made of spring steel, and therefore
were inclined to the hardness associated with that metallurgy, rather
than being "hardenable" in any traditional sense.
        Not being a metallurgist, this is just a SWAG. Perhaps someone
else can comment.
        BTW, I rechecked my sales brochure, and the water pump is indeed
black, as someone else pointed out. Another case of failing memory! Man,

do I hate getting old!!! I was going to say something else, but I 
forgot what it was... =;-o

        Cheers,

        Vance

Hi Dick,

I bought a rebuilt OD transmission from John Esposito for my TR250 
restoration, so I still have my original cross shaft and pin in my 
original trans (60K miles).

Sounds like maybe I should use the old original pin and cross shaft 
rather than the TRF replacements?

I think Nelson did not like the idea of the roll pin because they flexed

and would therefore not add much additional strength over the taper pin 
-- not much "sharing". Is a hardened roll pin different? Any thoughts 
would be appreciated.
