Spin-on FilterSpin-on Filters - A single filter part that is used once by spinning onto the filter base. The entire filter is disposed of at the end of the filter life. Spin-on filters are common and simple to maintain. In general, small Cat engines use spin-on fuel and lube filters. Some new small engines have moved to cartridge filter designs.

Cartridge FilterCartridge Filters - Cartridge filters are composed of separate filter elements and housing unit. The housing is retained and used for the life of the vehicle and the filter element cartridge is changed at the end of each filter service life. Cartridge filters eliminate waste since only the filter element is disposed of and the metallic housing is retained and reused during filter maintenance. In general, large Cat engines use cartridge filters for fuel and lube applications.Details are provided in this Special Publication, "Fluid Filters Components".Caterpillar offers a variety of fluid filters for applications in all Cat machines and engines. This Special Publication provides guidelines for using the filters. This Special Publication also details the design and quality built into the various Cat filters.Cat fluid filters are designed with optimized capacity and rating for Cat equipment. Cat offers fluids filters of three efficiency levels:
Standard Efficiency
Advanced High Efficiency
Ultra High EfficiencyDetailed information on the capacity and rating of the various fluid filters offered by Cat is given in this Special Publication, "Filter Capacity".Note: Substituting a higher-efficiency filter than recommended is typically safe. Substituting a lower efficiency filter than recommended is not acceptable.Caterpillar has introduced a "Plus" (+) designation for some filters. The "Plus" designation indicates an improved performance characteristic. Any of the three efficiency filter levels can also be designated as "Plus" if the filter has an improved characteristic. For example, a "Plus" Advanced Efficiency filter may have an improved characteristic such as better capacity or better flow restriction.In order to choose the appropriate filter size, efficiency and capacity, refer to your machine or engine Operation and Maintenance Manual and consult your local Cat dealer.Consult your Cat dealer for availability of Cat filters.
