Hello - thanks for the info.

The inner part turns by hand, the outer part with the grooves (where the belt actually touches/goes around) is completely seized/locked.

I just tried disconnecting the wiring to the compressor - hoping that would work - but it didnt.

Based upon the path/routing of the belt, I wont be able to use a shorter belt & skip the compressor, I'll need to have a pulley there.

Hmmm - so I guess that means I'll have to take out the compressor & experiment, and/or buy a new clutch for the compressor...
