WIX Filters 51197 Industrial Hydraulic Filter

The WIX 51197 Hydraulic Filter is a cartridge-style, full-flow hydraulic and transmission filter built in a metal canister for reliable contaminant removal in heavy-duty systems. Commonly installed in Caterpillar earthmoving equipment, Komatsu construction machinery, and Timberjack forestry gear, it provides hydraulic and transmission filtration to protect pumps, valves, and actuators under high-pressure operation. The filter uses enhanced cellulose media to capture particulates and is designed for preventive maintenance and long-term hydraulic system protection. Key specifications include: height 9.25 inches, outer diameter 4.00 inches, inner diameter 2.30 inches, nominal micron rating 23, and Beta ratio 2/20 = 10/24. Installation is cartridge canister type, and the application type is hydraulic and transmission fluid filtration. OEM references include Caterpillar 1R0719 and 1208757, Donaldson P559740, and Fleetguard HF6097, with cross reference NAPA Gold 1163, and common replacements Baldwin PT9555. Industries and equipment commonly served include construction, mining, forestry, and other industrial hydraulic systems where clean fluid supports pump efficiency and wear reduction.
