Part of the New Holland Repair Manuals.
This is the full factory service manual for the New Holland T4.85, T4.95 and T4.105 tractors, the same repair information a dealer technician works from. It covers the whole tractor: the FPT F5D 4-cylinder diesel engine and its common rail injection, cooling and lubrication, the clutch and both the mechanical and Power Shuttle transmissions, the four-wheel-drive front axle, the rear axle and PTO, the brakes, the three-point hydraulic lift and remote valves, hydrostatic steering, the cab and air conditioning, and a full electrical section with the wiring diagrams and electronic control units. Every section carries the specifications, torques, fault codes and step-by-step overhaul procedures, so you can put a fault right instead of guessing.
