Product Overview
The pump circulates coolant through the diesel engine and radiator while the mower is working under sustained load. A leaking shaft seal, noisy bearing, wobble at the pump shaft, or reduced coolant circulation can lead to overheating and make replacement necessary.
The 70 mm impeller size is an important distinguishing detail because Kubota uses different water-pump configurations across its diesel mower and front-mower families. Match the pump housing, impeller/pulley arrangement and mower model before installation.

Frequently Asked Questions
Q: Why does impeller size matter?
A: It helps distinguish pumps that may bolt to similar engines but use different coolant-flow hardware.
Q: Should the cooling system be flushed when changing the pump?
A: If coolant is contaminated or overdue, servicing the coolant and inspecting the rest of the system is sensible while the circuit is open.
