John Deere 9.0L Diesel Engines Level 14 Electronic Fuel System Technical Manual (CTM385)

CTM385 covers one thing in depth: the Denso high pressure common rail fuel system and the engine controls on the 9.0L PowerTech. If your tractor, sprayer, forager or combine has a fuel or engine control code, or you're replacing rail, pump or injector parts, this is where the procedures and specs are.
