1. ### Measure pulley center distance

Measure the distance between the centers of the two pulleys. This is denoted by C in the formula.

2. ### Calculate pulley diameters

Measure the diameters of the small pulley, denoted by D1, and the large pulley, D2.

3. ### Use the formula or enter measurements into online calculator

Using the formula “L= 2C + (D2-D1)/2 + (D2-D1)2/4C,” calculate length of the V-belt, where L denotes the length. The result can also be determined by entering the measurements into an online calculator provided by Baum Hydraulics Corp.
