FAQ

Q1: Is this oil cooler cover a direct bolt-on replacement for my Komatsu PC200-3 excavator?

A: Yes, this part (6150-61-2123) is designed as a direct bolt-on replacement for the Komatsu 6D125 engine found in the PC200-3 and PC400-6 models. It matches the OEM bolt pattern and dimensions. However, we strongly recommend removing your old cover and comparing the part number stamped on it to ensure it matches 6150-61-2123 before installation. You will also need a new gasket for a proper seal.

Q2: Does this cover come with the mounting bolts and gasket?

A: This listing is for the oil cooler cover only. The mounting bolts and gasket are typically sold separately. We advise purchasing a new gasket to ensure a leak-free seal during reinstallation. If you require bolts or a gasket, please contact our sales team for a complete kit.

Q3: How do I know if my oil cooler cover is failing and needs replacement?

A: Common signs of a failing oil cooler cover include visible oil leaks around the cover’s mating surface to the engine block, signs of coolant mixing with engine oil (milky appearance), or physical damage such as cracks or warping from overheating. If you notice any of these symptoms, replacing the cover immediately is crucial to prevent engine damage from oil starvation or overheating.
