Re: [DML] Advantages of 28 spline clutch discs?

["content22207" <brobertson@xxxxxxxxxxxx>]

10 splines are at least twice as deep, so the effective diameter
should be comparable.

Totally disagree about strength. It's virtually impossible to damage a
10 spline clutch disc once you're in them. The input shaft either
moves, or it comes to a screeching halt. None of this folding and
deforming of the splines that has caught me twice. I obviously respond
better to thick pieces of metal, not thin.

Received a flame mail that fine splines are standard issue on imports.
Need I say more? 

BTW: I have been struggling with this transmission all by myself.
People promise you the earth, moon and stars, but when time comes to
lay on your back in the driveway they disappear rapidly. Don't worry
-- they reappear just as quickly afterwards to press your botched
clutch disc off the input shaft.
