Product Description
The 24-1754 Alternator Pulley is a heavy-duty dual 4-groove pulley designed for compatible Delco 21SI-series alternators. Its dual four-groove configuration provides the belt contact area needed to transfer engine power reliably to the alternator in demanding truck, commercial, agricultural, and industrial charging-system applications.
The pulley features a 7/8-inch (.875") bore and is designed for approximately 14 mm belts. It crosses to Delco 10470322 and PIC 7940-1754, making those numbers useful when matching an existing alternator or pulley. Published Delco data identifies the 10470322 configuration as a bar-steel, dual 4-groove pulley.
