FAQ

Q: Will this water pump fit my Yanmar 4TNV106 engine in a John Deere excavator?
A: Yes, this pump (123900-42000) is a standard component for the 4TNV106 engine. It is used in many OEM applications including John Deere, Hitachi, and Yanmar equipment. We recommend checking the pump housing shape and impeller size against your old unit to confirm compatibility.

Q: What is the recommended installation procedure for this water pump?
A: Ensure the engine is cool and drained of coolant. Remove the old pump, clean the mounting surface, and apply a thin layer of gasket sealant (if no gasket is supplied). Torque the mounting bolts to the manufacturer’s specification (typically 25-30 Nm). Refill with fresh coolant and run the engine to check for leaks.

Q: How can I verify if this is the correct water pump before ordering?
A: Locate the part number on your current pump (usually stamped on the housing). Compare it to our OEM number: 123900-42000. Alternatively, provide us with your engine model (e.g., 4TNV106T) and serial number for cross-verification. We can also provide dimensional drawings upon request.
