Ford 555B Tractor Loader Backhoe Parts Catalog (1985–1988)

This parts catalog covers the Ford 555B 3-cylinder tractor loader backhoe, June 1985 through October 1988. Exploded views and application notes help match maintenance and repair parts to the machine’s build configuration before ordering.

Searchable PDF with Section Bookmarks

Figure lookup: Text search works in the figure index and parts tables. Embedded bookmarks open the search guide, index, parts section, abbreviation key, and hardware-conversion chart. Individual assemblies can be located by figure code.

The 556-page printable PDF contains 532 pages of parts figures and tables. The total also includes a five-page figure index, a one-page search guide, 14 pages of abbreviations, a two-page hardware-conversion chart, and two additional pages, one blank.

Drivetrain, Loader, and Backhoe Parts

These selected assembly groups outline the catalog’s coverage rather than reproduce its full index. Identification decals and the European tool kit are further examples of included content.

• Engine parts: Diesel cylinder block and head, crankshaft and flywheel, camshaft and valve gear, pistons and connecting rods, lubrication components, manifolds, exhaust, gasket sets, and overhaul kits.

• Transmission assemblies: Manual-reversing and power-reverse breakdowns, including clutches, gears, control valves, manifolds, oil-distribution components, filters, and cooler tubes.

• Axles, brakes, and steering: 2WD and FWD assemblies, rear differential and differential-lock linkage, service brakes, handbrake and twin-cable controls, and steering components.

• Hydraulic and loader systems: Reservoir and pump drive, Vickers pump, oil filter, pressure and return tubes, unload valve, loader controls, lift arms, linkage, cylinders, buckets, and counterweights.

• Backhoe configurations: Center-pivot and European side-shift assemblies, two- and four-lever controls, standard and hydraulically extendable dipsticks, booms, stabilizers, cylinders, and control valves.

• Fuel and cooling components: Diesel injection pump and injectors, fuel filters and sedimenter, cold-start equipment, air cleaner, throttle controls, radiator, water pump, and related components.

• Electrical and cab equipment: Regional harness assemblies, cab and ROPS lighting, battery, starter, alternator, instruments, seats, panels, wipers, heaters, and air-conditioning parts.

Suited to owners and parts staff who can identify the machine’s equipment and match numbered illustration callouts to catalog entries.

Parts Selection and Repair Limits

Each keyed table connects illustration references with part numbers, quantities, descriptions, application dates, and ordering notes. Entries distinguish regional fitment, cab or ROPS equipment, drive and transmission configurations, axle ratios, superseded parts, kit contents, locally sourced hardware, and items not serviced separately. Service-bulletin references identify related information to consult when selecting replacements.

“Front Wheels, 2WD,” for example, identifies wheel assembly D4NN1007A alongside the hub, bearing cups and cones, retainer, grease washer, slotted nut, cotter pin, and hub cap. Other tables identify seals, O-rings, shims, spacers, bushings, shafts, gears, repair kits, and fasteners.

Scope: This is a parts catalog, not a repair manual. It provides assembly breakdowns rather than diagnostic flowcharts, hydraulic pressure-test procedures, adjustment instructions, teardown sequences, wiring-circuit schematics, or component tightening-torque tables. A separate service manual is needed for disassembly, inspection, adjustment, and reassembly.

Secure raised loader or backhoe structures and heavy axle components, and depressurize hydraulic circuits with appropriate shop equipment before work begins.

Axle and Steering Changes

The AE3-184 and 710-19 front-drive groups distinguish housings, differential boxes, bevel gears and pinions, and reduction gears. Related figures identify driveshafts, steering arms and tie rods, transfer-case or gearbox components, center-housing internals, transmission shafts, shields, and front supports. The 710-19 group begins in January 1988.

Steering-cylinder listings distinguish assemblies through June 1987, dual-cylinder systems from July 1987, and single-cylinder systems from January 1988.

Replacement notes: “Reduction Gears, 710-19” calls for the old-style retaining ring, wheel carrier, and ring gear to be ordered together. “Steering Arms, FWD, AE3-184” likewise requires both revised arms when replacing either earlier arm. The 710-19 bevel-gear and pinion table also identifies a collapsible spacer.

Engine, Fuel, and Cooling Fitment

The engine section includes the stepped-stud block used from December 1986. “Pistons & Connecting Rods, Diesel” distinguishes Headland and regular piston styles and specifies complete-set replacement when changing styles.

Fuel listings separate the earlier single- and dual-filter arrangements from the three-cylinder sedimenter/filter assembly introduced in December 1986. Rotary injection-pump and injector breakdowns identify internal components and kits. Cooling tables distinguish water-pump pulley arrangements and related replacement requirements.

Hydraulic Controls and Backhoe Equipment

“Hydraulic Pump Assembly, Vickers” identifies pump seal and thrust-plate kits. Loader-valve tables distinguish two- and three-spool arrangements, including return-to-dig and 4-in-1 equipment where listed.

Backhoe figures separate swing posts, side-shift carriages and carriage-clamp components, hydraulic lines, transport locks, and extendable-dipstick foot controls. Dedicated breakdowns identify swing, lift, crowd, bucket, extension, and stabilizer cylinders, with corresponding valve groups.

Stabilizer-pad and North American bucket listings distinguish the available assemblies and their attaching parts. Cylinder tables also separate repair kits for different piston constructions.

Electrical Assemblies and Cab Revisions

North American and European figures distinguish left- and right-hand harness assemblies and their attached components. These are parts-identification views rather than electrical troubleshooting diagrams.

“Cab, Electrical” belongs to the revised groups used from March 1988, alongside separate subframe, cab, panel, trim, floor-mat, wiper, and defroster listings.

Component Dimensions and Hardware References

For the dual-cylinder power-steering assembly, the parts table identifies an outer tube with a 46 mm inside diameter and a piston with a 40 mm outside diameter. These are component-identification dimensions, not service clearances or adjustment settings.

Fastener entries specify threads, lengths, and grades or ISO classes, including G5, G8, CL 8.8, and CL 10.9. The multilingual abbreviation key explains catalog terminology. The metric/inch substitution chart excludes tapped holes and mixed metric/inch nut-and-bolt combinations from its substitution guidance.
