Part of the John Deere Repair Manuals.
This is the factory John Deere technical manual for the 2140 tractor, built 1980 to 1986, the same book dealer mechanics used. It covers the whole machine: the 3920 cm3 four cylinder diesel, fuel and air intake, the twin 12 volt electrical system with full wiring diagrams, the power train from clutch through Hi-Lo unit and creeper to the final drives and PTO, hydrostatic and manual steering, brakes, and the full hydraulic system including rockshaft and selective control valves. You get real teardown and rebuild procedures, machine specific torque figures, a color coded hydraulic schematic, and step by step tests for the complaints these tractors actually develop, like weak lift and shifting trouble. Cab, air conditioning, and roll guard sections are in there too.
