Industrial 6208-61-5400 Engine Oil Cooler Assembly

Description:

The Oil Cooler for Cummins B3.3 Engine used in Komatsu PC130-7 / PC130-8 excavators (Part Numbers: 4982639 / 6208-61-5400) is a heat exchanger component used to regulate engine oil temperature by transferring heat from engine oil to coolant or air. It is commonly installed in compact excavators and industrial diesel engine systems where stable oil temperature is required to maintain lubrication efficiency, prevent overheating, and ensure long engine service life. Maintenance teams and equipment operators use this oil cooler for engine cooling system repair, replacement of failed heat exchangers, and restoration of Komatsu excavator engine performance.

Applications:

The Oil Cooler for Cummins B3.3 engine is commonly used in Komatsu PC130-7, PC130-8 excavators, and other compact construction equipment where engine thermal management is critical. It is used in construction, earthmoving, and industrial machinery operating under continuous load conditions to maintain optimal oil viscosity and prevent engine wear caused by excessive heat.
