Need the right part number for your 1975-1978 Ford 550 Tractor Loader Backhoe? This 523-page Ford 550 parts catalog PDF covers the 550 and 550 3 CYL with exploded views of every assembly on the machine. You get complete parts lists for the loader and backhoe hydraulics: cylinder assemblies broken down to rods, pistons, glands, and seal kits, plus control valve sections detailed to the last O-ring and spring. Engine coverage runs from the 3-cylinder gas and diesel blocks through pistons, crankshaft, and full gasket and overhaul kits. Diagrams separate the 26.6 GPM Webster hydraulic pump from the 28.5 GPM pump assembly, so you order the right unit the first time. No more squinting at a worn casting number and hoping. Bookmarked with a live text layer; type the part name, jump to the diagram, place your order.
