FILTER ELEMENT (JD-AT81478)
Description:
John Deere AT81478 Fuel-Water Separator Filter Element is a genuine Original John Deere filtration component designed to help remove water and contaminants from diesel fuel before they can damage sensitive engine fuel-system components. Effective water separation helps maintain fuel quality, supports dependable engine operation and reduces the risk of corrosion and contamination-related problems.
The filter uses specially coated filtration media designed to capture and repel water while helping retain unwanted particles. This filtration process helps protect fuel-system components, including precision injection equipment, from the damaging effects of water-contaminated fuel.
Water in diesel fuel can contribute to corrosion, microbial growth and reduced fuel-system reliability. Regularly inspecting and replacing the AT81478 according to the machine’s recommended maintenance schedule helps maintain effective separation performance, protect engine components and reduce the risk of avoidable downtime.
Designed for compatible John Deere forestry, construction, agricultural and harvesting equipment, the AT81478 provides an application-specific fuel filtration solution. Checking the exact machine model and serial number before ordering helps ensure the correct filter element is selected.
