Ford issued this book as publication 40075510, the factory service manual for the 755, 755A, and 755B Tractor Loader Backhoe, and the complete 476-page Ford 755 service manual PDF is what you download here. Wiring diagrams anchor the electrical section, tracing the charging and starting circuits from battery through alternator, while hydraulic schematics map loader and backhoe flow right down to the system pressure checks. Both turbocharger builds, Air Research and Schwitzer, get their own overhaul and troubleshooting chapters, as do the transmissions, rear axle, brakes, and steering. Pull the head down in three stages, 90, 100, then 110 lbs. ft., and refill the hydraulic reservoir with its full 15 gallons (56.8 liters). A guessed torque figure cracks castings or drops a bearing. Bookmarks and a live text layer put the section you're after two taps away.
