To obtain an accurate measurement on the balance machine, an angle finder is used to determine a starting point. Consolo placed the crank into the machine. He then spun the crankshaft until the front rod journal (No. 1) was sitting vertically-almost like obtaining TDC. Consolo attached the first bob weight and used the angle finder to determine zero degrees. From there he rotated the crankshaft 180 degrees, attached the next bob weight to the last rod journal (No. 4), and set that bob weight with the angle finder to zero degrees. Next, he spun the crankshaft another 90 degrees, set the bob weight onto the next rod journal (No. 3), and set that one to zero degrees as well. Finally, Consolo rotated the crankshaft another 180 degrees and set that bob weight onto the second rod journal (No. 2).
