Fuel Filter / Water Separator Element 523-4987 for Caterpillar Excavators
523-4987 fuel filter/water separator for Caterpillar E320-E345GC excavators. OEM cross-reference verified. Bulk orders from IXIN Filter.
Description
This 523-4987 fuel filter is an ultra-high-efficiency fuel/water separator element engineered as a direct replacement for the Caterpillar 523-4987, widely used across CAT’s current-generation C7.1-powered excavator lineup. Built with meltblown filter media and a flange-mount cartridge design, it’s engineered to provide thorough contamination control so that only clean fuel reaches the engine.
Product Overview
The 523-4987 fuel filter uses meltblown filter media in a flange-type cartridge element, constructed with glass-filled nylon end caps and fiberglass roving impregnated with epoxy resin for durability. As an ultra-high-efficiency fuel/water separator, it’s designed to extend the life of the secondary fuel filter and protect precision fuel injection components from contamination. Each unit is dimensionally verified against OEM measurements and tested for filtration performance before shipment — not just matched by part number.

Frequently Asked Questions
Is this a spin-on filter or a cartridge element? This is a flange-mount cartridge element, designed to install into a reusable filter head rather than screw on and off directly like a spin-on filter.
Does this filter separate water from fuel? Yes. The 523-4987 functions as an ultra-high-efficiency fuel/water separator, designed to remove water and fine contaminants before fuel reaches the injection system.
Will this fit all the excavator models listed? It fits the E-series excavator and wheel loader models listed above, but fuel system configurations can vary by production year and serial number range. We recommend confirming your machine’s specific configuration before ordering, especially for bulk purchases.
Do you offer samples before a bulk order? Yes. We recommend requesting a sample for independent testing before committing to a bulk order, especially for first-time buyers.
