Part of the New Holland Repair Manuals.
This is the factory service manual for the New Holland CX Elevation and CR series combines, part number 47612507, dated March 2014. One book covers ten machines: the CX7080, CX7090, CX8070, CX8080 and CX8090 Elevation, and the CR8070, CR8080, CR9070, CR9080 and CR9090. It works through the machine the way New Holland builds it, then follows the crop path from header attachment through feeding, threshing, separation, residue handling, cleaning and unloading. The hydraulic section explains something worth knowing before you diagnose anything: the CCLS pump has no charge pump of its own and is charged from the hydrostatic return oil.

New Holland CX Elevation and CR Series (CX7080-CX8090, CR8070-CR9090) Common Problems This Manual Covers
Hydraulic functions are slow or weak, and the hydrostatic drive also feels off.
Do not treat those as two faults. The CCLS pump is charged from the hydrostatic return oil, which reaches it through the oil cooler at 60 l/min, so a restricted cooler or a hydrostatic problem starves the hydraulic pump directly. Check the return flow and the cooler first, then measure against the 197 bar high pressure relief setting before you condemn the CCLS pump itself.
Manual Section: Hydraulic SystemsThe header will not float properly, or lateral float feels harsh.
Check both accumulators, since the circuit uses two at different pressures. One is charged to 80 bar (1160 psi) and one to 100 bar (1450 psi), each 0.5 L. A soft accumulator makes the float feel dead or bouncy long before a cylinder or valve is at fault. The hydraulic section names the lateral flotation control valve, the pressure compensation valve, the minimum pressure valve and both accumulators on one numbered circuit.
Manual Section: Hydraulic SystemsSteering goes heavy under load while other functions work.
Steering is fed through a priority valve and a load-sensing shuttle valve and protected by its own steering relief valve, so it is the first thing to suffer when supply drops and the last thing to blame. Confirm the CCLS supply and the high pressure relief at 197 bar, then work the steering section for the motor, the cylinders and the relief valve. Only then look at the priority valve itself.
Manual Section: SteeringFrequently Asked Questions
Which combines does this manual cover?
Ten machines in two families: the CX7080, CX7090, CX8070, CX8080 and CX8090 Elevation, and the CR8070, CR8080, CR9070, CR9080 and CR9090. They share the drives, the hydraulics and the electrical architecture, and the manual names the series wherever a component differs, for instance in the hydraulic overview which is drawn separately for the CX7000 and CX8000 Elevation series.
How is the CCLS pump charged?
From the hydrostatic system's return oil, not from a charge pump of its own. Return oil reaches the pump through the oil cooler at 60 l/min (63 qts/min), and only under high demand does the CCLS pump pull an under-pressure on its suction line. That coupling matters in diagnosis: a hydrostatic problem shows up as a hydraulic one long before it shows up as a drive one.
What pressures should I set the accumulators to?
The lateral float circuit uses two accumulators, one charged to 80 bar (1160 psi) and one to 100 bar (1450 psi), each 0.5 L (17 oz). The high pressure relief valve in the hydraulic circuit is set to 197 bar (2856 psi). The hydraulic section carries the full numbered circuit with every valve and cylinder identified.
Is the crop path covered?
Yes, in flow order and each in its own section: attachments and headers, product feeding, threshing, separation, residue handling, cleaning, and crop storage and unloading. That runs from page 3899 to page 4892 and covers the feeder and stone trap, the concave and rotor settings, the sieves and fan, the chopper and the unloading auger.
How big is the manual and can I search it?
It runs to 4985 pages in English and is a searchable, printable PDF. Search the text, print the pages you need for the bench, and keep the rest on a laptop in the workshop.
What format is this New Holland CX7080 Elevation, CX7090 Elevation, CX8070?
Immediate download of the complete 4985-page searchable Service Manual (168 MB). Access it on any device, from a laptop at your desk to a phone in the field.
Are there any print restrictions on this New Holland CX7080 Elevation, CX7090?
Yes. The PDF has no DRM restrictions, so print any page or section you need for your shop. Works with any standard printer.
