Part of the John Deere Repair Manuals.
This is the factory technical manual (TM-4363) for the John Deere 1640, 1840, 2040, and 2040S utility tractors, all 1,256 pages of it. These are the four-cylinder 3920 cm3 (239 cu.in.) diesels rated at 2500 rpm, and this book covers every bolt on them: tractor separation and split procedures, the collar shift and Hi-Lo and creeper transmissions, final drives, PTO, mechanical front wheel drive, hydrostatic and manual steering, brakes, rockshaft and selective control valves, plus the OPU and SG2 cabs with air conditioning. You get specifications, special tools, wear limits, and step-by-step teardown and assembly with photos. If you are keeping one of these tractors working instead of paying a dealer, this is the book the dealer techs used.
