Product Overview
Part 721250-42700 is used across multiple Yanmar compact-tractor applications and is commonly associated with 3T80/3T90-family engine installations. Replacing a worn pump helps restore coolant movement through the block and radiator before overheating damages the head gasket or cylinder head.
Fitment should be confirmed by the 721250-42700 number and the original pump configuration. John Deere 1050 applications are sometimes cross-listed with this pump family, but configuration can vary, so the Yanmar number and physical layout are the safest ordering checks.
