Re: Souces of Timing/Drive Pulleys

John:

I suspect they are the same function but different mfg. The ones I meant
are small and have no keyway. A good picture at:

The Transtorque GT ones.

I'm familiar with QD bushings which function the same way but are part of
the pulley. One taper is cut in the pulley and the other on a keyed, split
hub portion. They are pulled together by bolts. Are these what you are
thinking of? If not, my knowledge is exhausted.
