Komatsu 206-03-63111 Hydraulic Oil Cooler Assembly

The 206-03-63111 hydraulic oil cooler is engineered for Komatsu 20-ton class excavators. It utilizes a plate-fin aluminum core design to provide efficient heat rejection for the hydraulic circuit under continuous heavy-duty operation. This unit serves as a direct replacement for OEM part numbers 206-03-63110 and 20Y-03-23110. It is designed to withstand high-pressure hydraulic flow and thermal cycling typical in construction and excavation environments. The cooler assembly includes mounting provisions compatible with the original equipment frame structure.
