Product Overview
The original title only listed a handful of tractors, but Yanmar replacement catalogs show this pump family across a much broader group of F and FX machines. It is the engine-driven coolant pump that circulates coolant through the block and radiator, and wear at the seal or bearing can lead to leakage, noise and overheating.
The 129107-42002 family is also cross-listed in some compact John Deere applications that use related Yanmar engines. Because imported Yanmar tractors can have model- and engine-specific cooling layouts, the old pump number and housing pattern should still be compared before ordering.

Before You Order
Use the pump number and engine model—not tractor model alone—to confirm fitment. Check whether a gasket is supplied and inspect the belt, pulley and cooling-system condition during service.
Frequently Asked Questions
Does this fit more Yanmar models than F195/FX195/F235/FX235/F255?
Yes. Replacement catalogs list this pump family across many F- and FX-series models.
Why are John Deere models listed?
Several John Deere compact tractors use Yanmar-built engines and cross-reference this pump family, but engine identification should be verified.
What usually causes water-pump replacement?
Seal leakage, noisy or loose bearings, shaft play and loss of coolant circulation are common reasons.
