Tracking down parts for a 1984-1985 Ford 555A Tractor Loader Backhoe? This 477-page Ford 555A parts catalog PDF maps every assembly on the machine, from the front axle to the backhoe boom. You get exploded views keyed to factory part numbers for the engine, transmission, torque converter, hydraulic control valves, loader, and backhoe, so you can identify the exact seal, bearing, or spool before you call the parts counter. Power steering, brakes, FWD front axle, cooling system, fuel tank, even wheel weights: every system is broken out piece by piece. Cross-check what's bolted to your machine against real factory data, like the 28.5 GPM hydraulic pump assembly and the 2400 PSI relief valve. Ordering the wrong seal kit twice gets old fast. This bookmarked PDF has a live text layer; punch in a part number, jump to the diagram, and place the order.

Ford New Holland 555A Tractor Loader Backhoe Common Problems This Manual Covers
Ford 555A transmission has no drive, need suction screen and hydraulic pump part numbers
Check the hydraulic reservoir and pump drive exploded view on page 140. The suction hose, return tube, and filter assembly are itemized with part numbers there. If the pump is suspect, the 28.5 GPM pump assembly is listed on page 201. Confirm your serial number range in the parts index before ordering.
Manual Section: Hydraulic Reservoir, Pump Drive, Suction Hose, Return Tube, Filter Assembly p. 140Metal in the pan, need torque converter gasket, bearing, and spacer part numbers
Check the torque converter breakdown on page 159. The support, spacer, gasket, bearing, and mounting bolts are all itemized with part numbers there. Inspect the flywheel parts listing on page 282 if the flex plate cracked. Debris from a failed converter usually reaches the 28.5 GPM main pump, listed on page 201.
Manual Section: Torque Converter Support, Torque Converter Spacer, Torque Converter Gasket, Torque Converter Bearing, Torque Converter Bolt p. 159Hydraulics slow under load, can't identify control valve seal kit and relief valve part numbers
Check the hydraulic control valve section starting on page 451. Spool valves, relief valve assemblies, seals, and springs are itemized there by valve section. Verify you order the relief assembly matching the 2400 PSI rating shown on page 452, and count your valve sections before buying seal kits so nothing comes up short.
Manual Section: Hydraulic Control Valve p. 451Steering hard and jerky, need power steering pump, reservoir, and valve assembly part numbers
Check the power steering pump and reservoir breakdown on page 32. The pump assembly, reservoir, and valve assembly carry separate part numbers. Match the valve rated at 1600 PSI shown on page 33 to your pump before ordering, and grab the reservoir seals while you're in there; they rarely survive disassembly.
