To estimate the belt size of a furnace, the first step is to _____ .
A) Measure the length of the old belt
B) Measure the diameters of the drive pulley and the driven pulley and add the two diameter together
C) Measure the width of the old belt
D) Measure the center-to-center distance between the motor shaft and the blower shaft

Measuring the center-to-center distance between the motor shaft and the blower shaft is the most accurate way to estimate the belt size of a furnace. This measurement will allow for the selection of a belt that is the proper length and provides the correct tension for optimal performance. Measuring the old belt length or width may not provide accurate sizing information, and adding the diameters of the pulleys together may not take into account factors like belt tension or the specific design of the furnace.
