Rebuilding a Ford 455 tractor-loader-backhoe, from the diesel's bottom end to the transfer case, is exactly what this Ford 455 repair manual PDF was written for: 522 pages of factory procedure under OEM number 40045510. Hydraulic work dominates the book; the loader and backhoe circuits take up better than a quarter of it, with pressure tests, component overhauls, and schematics that trace oil from pump to spool to cylinder. Wiring diagrams map the charging and starting circuits, and each system (fuel, clutch, transmission, rear axle, steering) closes with its own troubleshooting and specifications. Torque the cylinder head bolts in three progressive steps up to 110 lbs. ft. (149 Nm) with the engine cold, then pull the fuel line nuts to 25 lbs. ft. (30 Nm), straight off the factory table. Guess at a spec and you buy the gasket set twice. Bookmarked and text-searchable, this PDF puts you two clicks from the section your 455 is waiting on.
