Small diameter SBM water pump pulley

I appreciate our trying something new. The gathering of parts to make your way. I like to watch to see if I did it right. But the belt surface area on your crankshaft pulley seems insufficient for "all" of your accessories (WP, PS, AC and ALT). Of course I do not know your final application.

The Alt is ran off of the AC... It's the same principle as a serpentine setup.

I can run it a different way, AC runs off of crank and the other belt runs Alt, PS and WP... if this doesn't work once installed.

The other way the AC is mounted up high and makes the motor look like a Farm All Tractor!!!
