Kukje HRU2201000B9 Cylinder Head Assembly

This complete cylinder head assembly is engineered for the Kukje A2300 series 2.3L three-cylinder diesel engines. The unit includes the cylinder head casting, intake and exhaust valves, valve springs, retainers, and guides pre-assembled. It replaces Kukje part numbers HRU2201000B9 and HRU220C001B9, and Branson/TYM part number EA00004878A. The head casting is manufactured from high-grade cast iron to withstand high combustion pressures and thermal cycling typical in agricultural tractor applications. The valve train components are heat-treated for wear resistance and consistent seating performance. This assembly restores compression and valve train geometry to original specifications without requiring separate machining or valve job labor. Direct fitment applies to Branson tractor models 4520C, 5530R, 5025CX, 5530C, and 5025R equipped with the Kukje A2300N2, A2300-21, or A2300N2-ATC engine variants. Installation requires new head bolts, head gasket, and proper torque sequence per the engine service manual.
