1978–1988 Ford 555 Backhoe Loader Parts Catalog

This Ford 555 parts catalog covers the 1978–1988 tractor loader backhoe, with three-cylinder gasoline and diesel applications and 2WD or 4WD configurations. Numbered assembly illustrations link to OEM part numbers, quantities and application notes for replacement-parts identification.

Search and illustration detail: Figure headings, parts lists and the index are searchable. Six PDF bookmarks provide section-level navigation. Illustration callouts require visual lookup, and the smaller numbers in electrical layouts are readable when enlarged.

• Engine and fuel: Exploded views of cylinder blocks, heads, pistons, fuel injection pumps and Zenith carburetors, with engine gasket and overhaul-kit listings.

• Transmission and axles: Manual reversing and power reverse torque-converter assemblies, synchromesh gears, independent-PTO components, FWD transfer cases and differential-lock linkage.

• Hydraulics and steering: Webster and Vickers pump listings, reservoirs, filters, unload valves, loader control valves and power-steering component identification.

• Loader and backhoe: Lift-arm linkages, standard and extendable dipsticks, swing cylinders, stabilizer pads, 4-in-1 buckets and center-pivot or side-shift assemblies.

• Electrical and cab: North American and European harness layouts, starter and alternator parts, instrument clusters, cab equipment, ROPS, fenders and decals.

The catalog is suited to mechanics and owners who can identify the installed assemblies and read exploded parts diagrams when planning a repair.

Engine, Fuel and Cooling Parts

The engine listings distinguish gasoline and diesel components, including the stepped-stud block, crankshaft and valve gear. Exhaust manifolds, cooling radiators and water pumps have their own breakdowns.

Figure 06D02, Pistons & Connecting Rods, Diesel, separates Headland and regular piston designs and flags complete-set replacement when changing styles. These notes help match piston and ring selections before ordering engine repair parts.

The rotary fuel injection pump has an internal exploded view and a head-and-rotor assembly listing. Separate pages cover injectors, single and dual fuel filters, the Zenith carburetor and gasoline fuel pump.

Transmission, Axle and Steering Variants

The driveline sections distinguish the 6 x 4 manual reversing transmission from the 4 x 4 power reverse torque-converter transmission. Figure 07B02 identifies the synchromesh version, with separate clutch-and-gear illustrations and listings for dump-valve solenoids.

Front and rear wheel assemblies, front-end weights and swinging drawbars are cataloged alongside the AE3-184 FWD axle and transfer-case controls. Rear differential lists identify alternative gear ratios, casting references and shim sizes.

Figure 03B01, Power Steering Motor & Column, separates HGA10034 and HGA10040 seals, covers and cap screws. Their different screw threads matter during repair because a mismatched fastener can damage the cover threads.

Spindle-and-bushing repair kits are distinguished by the 1.13-inch and 1.23-inch spindle-pin diameters. Steering-cylinder rod sizes and O-ring dimensions are parts-identification data; they do not provide inspection limits or adjustment procedures.

Loader Hydraulics and Backhoe Attachments

Figure 05E01, Control Valve Assembly, Two Spool, and the corresponding three-spool illustration identify valve sections, relief components and return-to-dig parts. Pump-drive, reservoir and filter drawings show the associated hoses, tubes and fittings.

Backhoe coverage distinguishes two-lever and four-lever controls, center-pivot and European side-shift layouts, and standard or hydraulically extendable dipsticks. Cylinder breakdowns identify glands, pistons, seals and repair kits. Side-shift carriage clamps, boom transport locks and bucket teeth have separate listings.

Electrical Layouts and Catalog Limits

Figure 11A01, Electrical System, North America, LH, shows harness and component locations. European electrical layouts and cab wiring illustrations accompany the starter, alternator and instrument-cluster parts lists. Cab heaters, air conditioning, wipers and factory paint part numbers are also included.

This is a parts reference. It does not contain complete wiring schematics, hydraulic flow diagrams or step-by-step disassembly, overhaul and adjustment procedures. Listed dimensions and component ratings are not workshop test specifications or tolerance charts.

Consult a qualified technician and the appropriate service instructions for work involving hydraulic pressure or heavy loader and backhoe assemblies.
