Perkins original Perkins 7C-2239 Common Rail Diesel Fuel Injector Replacement for Perkins 3500A 3508 3512 3516 Engine original new injector

Engineered for the most demanding industrial environments, this Perkins 3512A Series fuel injector delivers consistent high-pressure performance across mining, marine, power generation, and oilfield applications. It is cross-referenced to multiple Perkins OE references including 4W-3563, 7C-0345, 10R3053, 9Y-0052, 7E-2269, 0R-0906, 0R-175, 7C-4173, 7C-9576, and 7E-6048, providing flexible sourcing for fleet operators and aftermarket distributors managing large Perkins 3512A, 3512B, 3512C, and 3516 engine populations.

The injector features a multi-hole nozzle optimized for fine atomization, supporting injection pressures up to 1800–2200 bar to ensure deeper fuel penetration and more complete combustion. This results in improved fuel economy, lower exhaust emissions, and stable engine output under continuous heavy load. Its hardened alloy body construction provides exceptional resistance to wear, corrosion, and thermal fatigue, ensuring long service life even in high-temperature and high-pressure operating conditions typical of 3512A/B/C platforms.

Designed as a direct OEM fit replacement, the unit installs without modification and integrates seamlessly with existing fuel system calibration. Routine maintenance is straightforward: operators are advised to use high-quality diesel fuel, periodically inspect for leaks, carbon buildup, or spray pattern degradation, and recalibrate injectors during scheduled engine overhauls. With multiple equivalent reference numbers available, this component offers a cost-effective, reliable supply chain solution for distributors, rebuild shops, and end users maintaining Perkins 3512A Series diesel engines.
