Caterpillar Inc. 4N-5834 Oil Filter Assembly

Cat 4N-5834 is Caterpillar’s OEM foam filter element, designed with a 13 mm thick foam media that slides into Cat filter assemblies available across a broad range of equipment. This part is specified for use in machines such as the Caterpillar 120C, 515, 518, 518C, 525, 528, 528B, 530B, and 545, where it serves as the replaceable filtration media within the appropriate canister. Being an OEM Cat part, 4N-5834 is built to exacting Caterpillar specifications to maintain fit, filtration efficiency, and compatibility with the surrounding housing and seals. The foam media is chosen for its ability to trap dust and particulates as part of the machine's filtration strategy, supporting sustained engine or hydraulic system performance by preventing debris ingress. As a catalog-listed part, 4N-5834 is identified by Cat's part numbering scheme to ensure correct replacement in the listed model family and similar assemblies, making it a precise option for customers maintaining older Cat equipment or stocking standard filter elements for known Cat configurations.
