New Holland CR920-CR980 Common Problems This Manual Covers
CCM error codes on the monitor with no explanation of what they mean or where to start
Section 55 chapters 18 through 23 list every CCM1, CCM2, CCM3, engine, HHC and ASP code with the circuit it monitors and what to check. Cross reference the Connectors and Electrical Schematics chapters to probe the actual wire instead of swapping parts on a guess.
Manual Section: Electrical - Fault Code Chapters (Section 55, ch. 18-23) p. 1749Turbocharger, injection regulation and head gasket trouble on higher-hour engines, especially the CR980
Start with the Engine Fault Codes chapter in Section 55 to confirm what the controller is actually complaining about, then work through Section 10 for the cooling system and fuel system procedures and the remove and replace sequence when the head or turbo has to come off.
Manual Section: Engine (Section 10) + Engine Fault Codes (Section 55) p. 1749Electric concave or separation grate adjustment fails mid-harvest
The Threshing Systems electrical chapter gives circuit descriptions and diagnostics for the adjustment actuators, and the schematics show every connector in the run. Most of these faults are a bad plug or dead actuator, both findable in an hour with a meter and the pinouts in the Connectors chapter.
Manual Section: Electrical - Threshing Systems + Schematics (Section 55) p. 1542Feeder house slugs, rattles and stops mid-field as the chain and lower feed roll wear
Section 60 covers the feeder house, feeder drives and stone ejection system, with disassembly, replacement and adjustment procedures for the chain and the lower feed roll. Set the chain tension by the factory procedure when you install it: an over-tight chain wears the feeder house floor, a slack one slugs the throat.
Manual Section: Product Feeding (Section 60) p. 2807Frequently Asked Questions
My combine is flashing an error code on the InfoView monitor. Will this manual tell me what it actually means?
Yes, and this is the main reason to own the book. Section 55 has dedicated chapters for CCM1, CCM2 and CCM3 error codes, plus engine fault codes, HHC diagnostic codes and ASP codes - over a thousand physical pages of listings (pages 1749-2806) tied to the circuit each code watches. You look up the number, trace the listed connectors on the schematics, and fix the cause. Clearing a code without fixing the circuit just brings it back on the next header engage. p. 1749
The electric concave or separation grate adjustment quit responding. Can I trace it with this manual?
This is a known sore spot on these machines, and it is almost always an actuator, a corroded connector or a CCM output - not the mechanism itself. The Threshing Systems electrical chapter walks the circuit, the Electrical Schematics chapter shows every wire in the run, and the Connectors chapter shows the plug faces so you probe the right pins. With a meter and this book it is an afternoon in the shop, not a dealer call during harvest. p. 1542
Does it cover the hydrostatic drive properly, including refilling after a pump swap?
Section 29 covers the hydrostatic system front to back: how it works, pressure testing and troubleshooting, pump and motor repair, the powered rear axle, and the filling and start-up procedure. That last one matters most - running a fresh pump without the proper fill and purge is how people wreck it in the first ten minutes. Having the factory procedure in writing pays for the book on its own. p. 625
The CR980 runs the big 10.3L engine. Is that covered, or just the 7.5L?
Straight answer: the 7.5L New Holland engine (the CNH675 in the CR920 and CR940) gets the full treatment - remove and replace, cooling system, fuel system. The 7.8L and 10.3L get description of operation plus the shared engine module components: the engine gearbox and clutch pack in Section 14 are covered with full removal and rebuild for all five models, and engine fault codes for every variant live in Section 55. For a complete 10.3L teardown you would want the engine maker's book alongside this one. p. 227
3,516 pages is a lot. How do I actually find anything in it?
The PDF has native two-level bookmarks: click the section, then the chapter. The 17 sections follow New Holland's standard numbering (10 engine, 21 transmission, 29 hydrostatic, 55 electrical, 66 threshing and so on), so if you have used a NH book before you already know where things live. Torque figures sit inside the procedures where you need them - the transmission chapter, for example, gives the drive shaft nut at 150-170 N.m (111-125 ft. lbs.). p. 3
