Yanmar & Komatsu Fuel Filter Assembly | Part YM129612-55620

Product Overview

The YM129612-55620 Fuel Filter Assembly (also referenced as 129100-55621) is a critical protection component for diesel engines operating in high-dust industrial and construction environments. This assembly is engineered to remove water, sediment, and microscopic particulates from the fuel stream before they reach the precision components of the injection system. By ensuring a clean fuel supply, it prevents engine hesitation, protects injectors from abrasive wear, and maintains the consistent power output required for heavy-duty excavation and loading.

This filtration unit is designed for broad compatibility across Yanmar and Komatsu powerplants. It is a precise fit for Yanmar 4TNE88 and 3TNE84T engines, as well as Komatsu 3D84E-3 and 4D88E-3 series engines. Beyond the engine itself, it is a standard maintenance part for specific machinery such as Komatsu PC35R-8 and PC45R-8 excavators, and SK714, SK815, SK818, and SK820 series skid steer loaders. The assembly features a robust metal housing and a clear or metal bowl depending on the specific configuration, designed to withstand the thermal cycles and vibrations of professional job sites.
