Product Overview
The water pump circulates coolant through the engine and radiator. Bearing wear, seal leakage or impeller damage can lead to coolant loss, belt noise, overheating or poor coolant circulation—problems that should be corrected before they cause cylinder-head or gasket damage.
The 70mm-impeller configuration is used across D905/D1005/D1105 and selected V1305/V1505 equipment. Matching the engine model, pump number and impeller configuration is more dependable than ordering by vehicle model alone.

Frequently Asked Questions
Q: Why is impeller size important?
A: Kubota uses visually similar pumps with different impeller and housing configurations. Match the 70mm specification and part number.
Q: Should I replace the belt at the same time?
A: Inspect the belt, pulley, hoses and thermostat while the cooling system is open and replace worn components as needed.
Confirm the existing water-pump number, impeller size and engine model before ordering.
