  • Information
This genuine Foton Cummins Cylinder Head is an original OEM core spare part tailored for Foton Cummins ISF3.8 and ISF4.5 diesel engines, corresponding to official OE numbers 5271866, 5565074 and 5624923. Manufactured strictly in accordance with Beijing Foton Cummins Engine Co., Ltd official standards, it adopts original design drawings, standard alloy formulas and professional production processes, fully consistent with the original cylinder heads equipped on brand-new Foton medium and light commercial vehicles.

Different from ordinary aftermarket cylinder heads with recycled materials, this cylinder head uses high-purity low-alloy ductile iron blank. Featuring excellent high-temperature resistance, tensile strength and thermal fatigue resistance, it effectively avoids common failures such as cracking, deformation, air leakage, water leakage and oil leakage during long-term high-temperature and high-pressure engine operation, greatly reducing repeated maintenance costs. All raw materials are equipped with complete metallurgical inspection reports and pass strict spectral sampling tests to ensure zero defective raw materials.

OEM Replacement Cylinder Head 5271866


The product adopts advanced lost foam precision casting technology to eliminate sand holes, pores and uneven wall thickness defects. Every blank undergoes ultrasonic internal defect scanning, and only flawless blanks enter precision processing. Equipped with imported 5-axis CNC machining centers, all assembly holes, water channels, oil passages and combustion chamber surfaces achieve micron-level precision. The sealing surface flatness is strictly controlled within 0.02mm for perfect gasket fitting. Valve seats and guide holes are treated with high-frequency quenching to enhance surface hardness and wear resistance, ensuring long-term stable engine operation. All processing data is fully recorded and traceable without cutting corners on structure or wall thickness.
Every finished Foton Cummins Cylinder Head passes three strict professional tests before delivery, including high-pressure hydraulic leakage test (30-minute constant pressure detection), extreme temperature aging cycle test (over 800 cold and hot alternating cycles), and real engine bench test (6-hour full-condition operation). All test data fully complies with OEM original standards to ensure zero leakage, stable compression and no power attenuation after installation.
