C56612901 Starter Motor is a high-torque starting motor designed for ISZ14 heavy-duty diesel engine. Powered by 24V vehicle battery, it drives crankshaft rotation to complete engine ignition start. This aftermarket replacement starter resolves hard cranking, intermittent no-start and abnormal rattling noise from starter compartment caused by internal armature wear, solenoid failure and pinion gear abrasion. Stable starting performance avoids vehicle startup failure on long-haul freight routes, suitable for heavy trucks working continuous highway transportation and heavy-load hauling.
Product Advantages High-strature copper winding delivers stable large starting torque under low temperature. Hardened drive pinion resists impact wear during meshing. High-quality solenoid guarantees reliable engagement and disengagement. Every starter undergoes no-load test and torque inspection before shipment, OEM mounting flange supports direct bolt-on installation.
