1978–1988 Ford Backhoe Loader 555 Parts Catalog (OEM)

• Details 1978–1988 Ford 555 tractor loader backhoe configurations, including 3-cylinder gasoline and diesel models with 2WD or 4WD drivelines
• Features 592 pages of exploded-view diagrams, precise parts lists, and complete assembly schematics
• Provides granular component indexing for the hydraulic reservoir, power steering, and entire drivetrain
• Serves as a technical reference for identifying replacement fasteners, factory seals, and structural components directly from the manufacturer's layout
• Covers the syncromesh transmission, fuel injection pump, Zenith carburetor, extendable dipstick, swing cylinders, 4-in-1 buckets, and dump valve solenoids
• Identifies precise OEM P/Ns for Vickers pumps, Webster pumps, independent PTOs, hydraulic unload valves, stabilizer pads, rollover protection systems, and swinging drawbars

Component Assembly Breakdowns

The PDF parts catalog maps out the mechanical structure of the heavy-duty backhoe loader directly from the ground up. By referencing these highly detailed component layout views during troubleshooting, mechanics can match OEM P/Ns (Part Numbers) directly to the factory hardware, completely eliminating the risk of ordering incorrect heavy equipment components. You will find exact part breakdowns for the front wheel assemblies, standard and power-adjustable rear wheels, alongside optional front-end weight kits. The engine section covers the cylinder block, exhaust manifolds, cooling radiators, and fuel delivery systems for both gas and diesel power plants.

Moving down the driveline, the exploded-view drawings lay out reversing transmission cases, torque converters, and the transfer case controls specific to 4WD units. When diagnosing the fluid systems, the manual indexes the entire circuit with hydraulic flow diagrams, highlighting the hydraulic reservoir, filtration setups, and control valves. Electrical pages cover starting motors, alternators, the instrument cluster, and complete wiring diagrams, while the concluding sections catalog the cab, fenders, ROPS frame, decals, and factory finish paint codes.

Technical References and Specifications

Beyond part numbers, this catalog provides critical assembly specifications and identification data for field maintenance. While this is a dedicated parts reference, the sequenced routing schematics and assembly views act as a visual step-by-step guide for teardown and reassembly. This layout empowers you to tackle complex repair jobs—like rebuilding the syncromesh transmission or overhauling the fuel injection pump—without relying on expensive dealership labor rates.

Front axle spindle pin diameters are documented at either 1.13" or 1.23", depending on your specific production series. In the power steering circuit, spool valve relief settings are specified at 1600 PSI. Precision tolerance charts outline differential shim thickness ranges from 0.038" to 0.090", while steering system cylinder rod diameters are noted at 0.685". The manual also cross-references O-ring dimensions across the manifold and cylinder assemblies to streamline routine seal replacement. This specific workshop advantage eliminates measuring degraded seals with calipers, saving hours of parts-counter guesswork. Since heavy equipment maintenance involves high-pressure hydraulics and significant mechanical loads, always consult a certified technician and verify proper safety protocols before servicing these systems.
