Fuel Water Separator 117-4089 / 145-8862 for Caterpillar Excavators, Loaders & Track-Type Equipment
117-4089 fuel water separator for Caterpillar excavators, loaders, and 3116/3126E engines. OEM cross-reference verified. Orders from IXIN Filter.
Description
This 117-4089 fuel water separator is a standard-efficiency spin-on filter engineered as a direct replacement for the Caterpillar 117-4089, sold as an assembly alongside the closely related 145-8862 filter head/base. It’s one of the most widely used fuel/water separators across CAT’s C-series excavator, wheel loader, and track-type equipment lineup built around the 3116, 3066, 3054T, 3064, 3046, and 3126E engine family.
Product Overview
The 117-4089 fuel water separator is designed to remove essentially all free water and the majority of emulsified water from diesel fuel, along with fine particulate contamination, helping extend the service life of the secondary fuel filter and protect precision fuel injectors from premature wear. As explained in this overview of fuel water separator function, water in diesel fuel can cause corrosion, microbial growth, and injector damage if it isn’t removed before reaching the engine. As a spin-on filter, it offers straightforward installation and a reliable seal. Each unit is dimensionally verified against OEM measurements and tested for filtration performance before shipment — not just matched by part number.
