Our water pumps are new replacement assemblies that include the pulley and gasket surfaces ready to install. They are designed to circulate coolant through the engine block and radiator to maintain operating temperature on Kubota diesel engines used in Bobcat mini-excavators.
Are Bobcat mini-excavator water pumps interchangeable across models?
Not always, since different Bobcat mini-excavators use different Kubota engine setups. For example, part 15521-73035 covers the 331 through 341 range while part 1A021-73033 covers the E-Series and 430ZHS and 435 machines.
