High-quality cylinder head suitable for Cat 3304, 3304DI, 3304PC, and 1N4304 models
Part No.1N4304 cylinder head for 3304 engine is a replacement bare head for direct-injection 4-cylinder heavy-duty diesel engines, widely used for overhaul of wheel loaders, bulldozers, motor graders and generator sets. It has five core features:
Calibrated spiral port for direct injection. Runner profile is cast to match direct injection combustion requirements. It creates well-controlled intake swirl synchronized with fuel spray for complete combustion. Carbon buildup is minimized, and airflow resistance stays consistent after long working hours.
Step locating bore for valve seat inserts. Double-step positioning controls press-fit depth precisely. The contact surface bears load evenly, preventing uneven loosening under cyclic thermal shock. It keeps the valve sealing band stable and reduces air leakage and lube consumption.
Crossed interleaved cooling gallery design. Interlaced water passages wrap combustion chambers and exhaust seats to eliminate stagnant hot zones. Balanced heat dissipation prevents unilateral thermal warping, reliable for nonstop outdoor site operation.
Integrated injector clamp pedestal. The mounting base for injector hold-down is cast as one piece with the head body. High rigidity ensures even compression on sealing gaskets, preventing high-pressure fuel leakage and maintaining stable fuel rail pressure.
Cyclic pressure test simulating temperature fluctuation. Apart from standard hydrostatic test, it goes through alternating pressure cycles to mimic heating and cooling during machine start-stop. Tiny seepage risks caused by thermal stress can be screened out to guarantee consistent bulk quality.
