Product Introduction
In modern diesel common rail powertrain systems, the synchronous coordination of fuel delivery and pressure build-up directly determines engine power output, emission compliance and operational stability. The 304-0678 actuator pump small flange with 31 integrated teeth and built-in fuel transfer pump is engineered as a core matching component for heavy-duty diesel engine common rail systems, filling the demand gap of OEM-level replacement and aftermarket maintenance for engineering machinery, commercial vehicles and industrial diesel units. It breaks the traditional split structure design and integrates drive flange, tooth transmission and fuel transfer function into one piece, perfectly adapting to high-load and long-cycle working scenarios of European and American diesel equipment.
🔧 Structural Design & Craftsmanship Advantage
This 304-0678 unit adopts compact small flange layout with standard 31 precision machined drive teeth, adopting high-alloy steel integral forging and vacuum heat treatment process. The tooth surface is polished to achieve precise meshing tolerance, effectively eliminating transmission backlash and abnormal wear during high-speed operation. The integrated fuel transfer pump adopts external gear pump structure, with optimized internal flow channel layout, compact overall size without extra installation space, realizing one-piece assembly and replacement, greatly simplifying the disassembly and maintenance process for repair technicians.
