Part of the New Holland Repair Manuals.
This 577-page New Holland TF76, TF78 repair manual PDF (OEM 604.64.016.00) is the factory service volume for both combines' drivetrain, hydraulics and electrics. Traction gearbox, brakes, final drives and steering axles start on page 15; the grain header with its knife and wobble box on page 55; the straw elevator on page 73; and the IVECO AIFO 8460 diesel with its injection pump and injectors on page 85. Wiring diagrams trace the starter circuit, engine throttle, reversing mechanism and unloading tube pin by pin across the CAN bus network, while the hydraulic and hydrostatic sections map the header height control valve and stack valves with every symbol explained. Calibration procedures for the header height electronic control and lateral float sensors keep your monitor honest through the season. Check the high pressure relief valve against its 160 bar setting, and refill the wobble box with 0.9 litres before the knife starts hammering. The serial number breakdown up front means you order the correct part the first time, and bookmarks plus a full text layer take you straight to the page.
