I am replacing an air compressor pump. The new pump has a different dia. pulley. According to the formula for sizing and the speed of my motor I need to use a 7.5" pulley. Should I get one based on actual outside dia. or the Datum dia. to turn the pump at the proper rpm?

A: If using 5/8" (B) belts; use the o.d. of the pulley for calculation. If using 1/2" (A) belts; add 0.375" to the datum diameter for the o.d. where the back side of the belt will ride.
