This heavy-duty starter is a 12V, 6.4 KW PLGR unit engineered primarily for Caterpillar 3176 diesel engines in Volvo ACL-series trucks (1994-2000). With an 11-tooth clockwise pinion and precise OEM dimensions—including a 55.1mm gear OD—it ensures a direct, bolt-on replacement. The starter consolidates multiple OEM part numbers from Delco, Denso, and Mitsubishi, offering a durable and reliable solution for commercial fleets. Built for industrial-grade performance, it provides the robust cranking power required for reliable starts in medium and heavy-duty truck applications.
