FAQ

Q: How can I confirm this water pump will fit my Komatsu engine?

A: The primary method is to check the engine model plate on your equipment. If your engine is a 6D155, S6D155, or SA6D155 variant, this pump is the correct type. Secondly, locate the part number on your existing pump (e.g., 6127-61-1181). If it matches any of the numbers listed, it is a direct replacement. We also recommend measuring the mounting bolt pattern and comparing it to the specifications provided.

Q: What is included with the water pump assembly? Is it ready to install?

A: Yes, this is a complete water pump assembly. It comes fully assembled with the impeller, shaft, and mechanical seal pre-installed in the housing. You do not need to purchase additional components to install it. However, we always recommend using a new gasket or O-ring (sold separately) for a leak-proof seal during installation.

Q: What maintenance should I perform when replacing this water pump?

A: While replacing the water pump, it is an excellent time to perform other cooling system maintenance. We recommend replacing the engine coolant, checking the condition of the radiator hoses, and inspecting the fan belt for wear. Flushing the cooling system before installing the new pump will help remove debris and ensure long service life for the new component.
