Product Description
The WAI 24-1506 Alternator Pulley is a heavy-duty 3-groove V-belt pulley designed for compatible Delco 25SI, 29SI, and 30SI alternators, including applications used on Mack trucks.
The pulley is machined from cold-rolled steel and designed for 13 mm V-belts. It measures approximately 89 mm (3.50 inches) in outside diameter and uses a 22.23 mm (7/8-inch) keyed bore. WAI specifically catalogs the 24-1506 as the replacement for Mack 310GC276.
Its solid-steel construction and three-groove configuration make it suitable for heavy-duty truck and industrial charging systems where multiple V-belts are used to drive the alternator.
