Part of the New Holland Repair Manuals.
This is the full factory service manual for the New Holland CR6090, CR7090, CR8080, CR8090 and CR9090 combines, the Tier 4A twin-rotor machines, the same service information a dealer technician works from. It covers the whole combine: the FPT Cursor diesel engine and the SCR aftertreatment, the main gearbox and drive, the transmission, the hydrostatic drive, the front and rear axle systems, the brakes and controls, the hydraulic systems, the steering, the tracks and track suspension, the cab climate control and the full electrical system with the wiring diagrams. It then walks the crop flow: product feeding, twin-rotor threshing, cleaning, residue handling and crop storage and unloading. Every section carries the specifications, torque data and capacities, the functional adjustments, the fault finding and the step-by-step removal, overhaul and installation procedures, so you can chase a threshing, hydrostatic or electrical problem and put it right instead of guessing.

New Holland New Holland CR6090 CR7090 CR8080 CR8090 CR9090 Common Problems This Manual Covers
Poor threshing, high grain loss, or grain damage.
Work the Twin-Rotor Threshing and Separation section: it covers the rotor speed, the concave clearance, the vane settings and the rasp-bar condition and gives the functional adjustments and grain-loss checks to balance a clean sample against grain damage.
Manual Section: Twin-Rotor Threshing and SeparationHydrostatic ground drive is weak, slow, or will not move the machine.
Work the Main Gearbox, Transmission and Hydrostatic Drive section: it covers the hydrostatic pump and motor, the charge circuit and the speed control and gives the pressure testing and fault diagnosis to find whether the pump, the motor or the charge pressure is behind the weak drive.
Manual Section: Main Gearbox, Transmission and Hydrostatic DriveDirty grain sample or grain loss over the cleaning shoe.
Work the Cleaning section: it covers the sieve and chaffer settings, the fan airflow and the self-levelling system and gives the functional adjustments and grain-loss checks to get a clean sample and keep the losses down.
Manual Section: CleaningEngine derates, smokes, or triggers SCR and DEF faults.
Work the Engine and Aftertreatment section: it covers the FPT Cursor fuel and injection, the aftercooler and the SCR and DEF dosing system and gives the specifications and diagnosis to cure derates, smoke and the aftertreatment faults.
Manual Section: Engine and AftertreatmentFrequently Asked Questions
Does the manual cover the twin-rotor threshing and separation adjustments?
Yes. The Twin-Rotor Threshing and Separation section covers the rotor cage and rasp bars, the concaves and grates and the rotor speed and vane settings, with the functional adjustments and wear-parts replacement to keep threshing clean and cut grain loss.
The hydrostatic ground drive is weak or will not move the combine - what does the manual cover?
The Main Gearbox, Transmission and Hydrostatic Drive section covers the hydrostatic pump and motor, the ground-drive transmission and the speed control, with the pressure testing and fault diagnosis to find a weak or dead hydrostatic drive.
Does the manual include the wiring diagrams and electronic diagnostics?
Yes. The Electrical System and Cab Climate Control section carries the wiring diagrams, the control modules and CAN bus, the sensors and actuators and the monitors, so you can trace an electrical or electronic fault on the CR combine.
Grain loss or a dirty sample over the cleaning shoe - is that covered?
Yes. The Cleaning section covers the sieve and chaffer settings, the fan airflow and the self-levelling system, with the functional adjustments and grain-loss checks to get a clean sample and keep the losses down.
Which models and engine does this manual cover?
It covers the New Holland CR6090, CR7090, CR8080, CR8090 and CR9090 Tier 4A twin-rotor combines with the FPT Cursor engine and SCR aftertreatment, including the hydrostatic drive, hydraulics, threshing, cleaning, residue and unloading systems.
