This is the factory chassis service manual for the McCormick ZTX Series tractors: the ZTX230, ZTX260 and ZTX280, the big horsepower end of the range. It runs 1,019 pages and is the book the dealer technician works from. It covers the tractor, the transmission, the front and rear axles, the hydraulics, the steering, brakes, cab and the electronic controllers, with full wiring and hydraulic schematics and calibration and error code procedures. The engine coverage is built around these tractors' electronic engine: the engine electronic control system, the CAPS common rail fuel system with its high pressure pumping, the fault codes and the datalink diagnostics, alongside engine removal. If you are chasing a fuel or engine management fault on a ZTX, this is the section that has the pressures and the diagnostic procedures.
