1988–1993 Ford 555C Tractor Loader Backhoe Parts Catalog

This illustrated parts catalog covers the Ford 555C tractor loader backhoe, with 2WD and 4WD configurations, regional equipment, and standard and turbocharged engine entries. It focuses on parts identification; written diagnostic and step-by-step repair procedures are not included.

• Engine and fuel system: Exploded assemblies for the block, crankshaft, pistons, valvetrain, turbocharger, injectors, and upper and lower DPS rotary injection-pump components.

• Powertrain: Transmission clutch and input-shaft assemblies, countershaft and output gears, shuttle-shift controls, front-drive components, and rear differential parts.

• Brakes and steering: Service-brake assemblies, transmission and twin-cable handbrakes, steering motor columns, and Cessna, TRW, and Cascade cylinder breakdowns.

• Hydraulics: Pump, reservoir, cooler, filter, and pump-drive parts, plus loader control-valve sections and two-to-three-spool conversion-kit listings.

• Loader equipment: Lift arms, bucket-level indicator, hydraulic lines, lift and bucket cylinders, multipurpose buckets, counterweights, and subframe components.

• Backhoe equipment: Center-pivot and side-shift frames, swing posts, control linkages, HED extendable-dipstick assemblies, and boom, crowd, bucket, swing, and stabilizer cylinders.

• Electrical and cab equipment: Harness placement views, starter and alternator breakdowns, ROPS and cab frames, interior fittings, and Sanden compressor-and-clutch parts.

Suited to owners and parts staff who can match an exploded-view reference to the assembly fitted to their machine.

Engine and Powertrain Parts Identification

Engine listings distinguish complete engines, short blocks, piston kits, bearing sizes, and upper and lower gasket kits. The DPS rotary injection pump is divided into upper and lower assembly figures, with separate listings for fuel injectors, the primer, sedimenter, and filter.

Transmission figures identify internal shafts, clutch components, shift forks, valve housings, and oil-cooler connections. Fine- and coarse-thread case hardware and output-gear revisions have separate application notes. Front-drive illustrations cover the differential box, bevel gear and pinion set, reduction gears, drive shafts, and transfer-case controls.

Steering, Hydraulics and Hardware Matching

Need to track down a specific hydraulic line or steering-cylinder seal kit? Numbered illustrations connect the pictured components to part numbers, quantities, and application notes.

The Cascade cylinder entries reverse left- and right-hand applications between 2WD and 4WD machines. Separate Cessna and TRW figures help you match the installed cylinder design before selecting its seal kit.

Hydraulic coverage includes individual bucket, lift, and auxiliary valve sections, along with reservoir, cooler, and pump-drive assemblies. Filter listings distinguish mounting arrangements and replacement assemblies. These are component breakdowns and line-placement drawings, not hydraulic flow schematics.

Chassis figures also identify wheel and front-end weight hardware, differential-lock linkage, shims, and steering-column gasket and seal kits. The hardware appendix cautions against treating similar metric and inch fasteners as interchangeable in tapped holes; mismatched threads can damage the mating parts.

Loader and Backhoe Configurations

Center-pivot and side-shift illustrations separate frame, swing-post, carriage-clamp, and hydraulic-line arrangements. Control-kit listings cover three- and four-lever conversions and conversion of HED control to a lever.

The extendable-dipstick drawings identify inner and outer channels, wear strips, shims, retaining hardware, and associated linkages. Cylinder listings include gland, piston, seal-kit, and replacement-update notes, helping distinguish an individual seal replacement from a coordinated component update.

Always secure the machine and relieve system pressure before inspecting parts or beginning any tear-down.

Electrical Layouts and Cab Assemblies

The left- and right-hand electrical-system views show harness placement, switches, fuse-block components, battery connections, and related hardware. They illustrate physical component locations rather than circuit connections.

Cab sections extend to interior trim, glazing, door hardware, wipers, heater components, and air-conditioning assemblies. The Sanden compressor-and-clutch figure separates the listed compressor, clutch, gasket, and seal components.

Wheel Fitment Examples from the Parts Lists

These wheel entries are a small sample of the component sizes and fitment details in the catalog.

Front wheels: The 2WD listing pairs an 8.00 x 16 rim with an 11 x 16 tire.

Rear wheels: A 15 x 24 rim is listed for a 16.9 x 24 tire. A separate entry pairs that rim size with an 18.4 x 24 tire for 4WD. These are catalog fitment entries, not workshop adjustment limits.

Catalog Navigation and PDF Contents

Text search and drawing detail: Parts-list text and figure headings support search; illustration callouts remain image-based. Embedded bookmarks open the index, main parts section, and reference appendices. Zooming helps separate closely grouped reference numbers in the electrical and hydraulic layouts.

One printable English-language PDF contains 494 pages: 470 pages of illustrations and parts lists, a five-page figure index, a 14-page abbreviations reference, and a two-page hardware-conversion appendix. The total also includes one figure-search instruction page, one introductory page, and one blank page.
