Fuel Filter 84170818 Case

The Fuel Filter / Fuel-Water Separator 84170818 for Case IH is a critical maintenance component designed to protect diesel engines from water contamination and solid particles that can cause premature wear, corrosion, and performance loss. Used across a wide range of Case IH construction and agricultural machines, this filter plays a key role in maintaining fuel system integrity under demanding operating conditions. This unit functions as a fuel/water separator, efficiently removing free water from diesel fuel before it reaches sensitive components such as injectors and high-pressure fuel pumps. By separating water at an early stage, it helps prevent internal corrosion, cylinder cavitation, and injector damage, which are common failure points in heavy-duty diesel engines. The filter features a pleated paper filter media, optimized to capture fine contaminants while maintaining consistent fuel flow. Its 96 mm outer diameter and 185 mm overall length provide sufficient filtration surface area for extended service intervals. The threaded center connection ensures a secure fit to the filter head, while the integrated water drain plug allows easy servicing and controlled water removal during routine maintenance.
