Roll the v belt along the flat surface until the paint mark rolls back to the flat surface. Measure the distance between the two pencil marks to determine the circumference of the v belt. The result can also be determined by entering the measurements into an online calculator provided by baum hydraulics corp.

Roll the v belt along the flat surface until the paint mark rolls back to the flat surface. I currently maintain a piece of machinery ca.1900 that uses just such a belt. Measure the distance between the two pencil marks to determine the circumference of the v belt.
