As the crankshaft rotates, the belt moves along its looped path and engages pulley grooves to transmit motion. This continuous movement allows accessories to operate in step with engine speed. The belt responds naturally to changes in rotation without driver input. Tension is maintained as the belt cycles through its drive path. The Mack 23961878 supports accessory operation through continuous rotational transfer.
