SINOTRUK HOWO Engine Electrical System A7 T7H D12 Gear-Reduction Starter Motor Assembly 24V VG1246090002

The VG1246090002 uses a gear-reduction structure to transfer the electric motor's high-speed rotation into increased torque at the starter drive, providing the cranking force required by a heavy-duty diesel engine. This starter is associated with 24V commercial vehicle electrical systems and is widely listed for SINOTRUK HOWO applications. A commonly listed configuration uses an 11-tooth pinion. The starter is used with heavy-duty engine platforms such as HOWO D12, where substantial cranking torque is required during engine startup. The starter drive uses a pinion gear to engage with the engine flywheel ring gear. Correct tooth count, mounting position, and engagement geometry are essential when selecting a replacement. The assembly incorporates an electric motor, reduction gear mechanism, electromagnetic solenoid, and starter drive, forming a complete starting unit for commercial vehicle applications.
