Product Overview
Specialist compact-tractor parts catalogs show this pump family across a wider group of Yanmar YM tractors, including YM1802, YM1810, YM1820, YM2001/2002/2020 and others. Engine references include several 3T70/3T72/3T75/3T80/3T84 variants, so engine identification is useful when a gray-market tractor model alone is ambiguous.
The water pump circulates coolant through the engine and radiator. A failed seal can leak coolant from the pump area, while bearing wear may create noise or pulley movement. Replace the gasket during installation and make sure the cooling system is clean so debris does not shorten the life of the new pump.

Confirm tractor model, engine model and pump/hub configuration. Yanmar gray-market tractors can have application differences not obvious from the model decal alone.
Frequently Asked Questions
What other Yanmar models use this pump family?

Should coolant be replaced when installing a water pump?
