Case IH CROSS-FLOW CF 80 Common Problems This Manual Covers
Case IH CF 80 hydraulic header won't lift, system pressure drops during operation
Check hydraulic oil level first; the tank holds approximately 60 liters (page 37). Inspect the reflux filter: the bypass valve opens at 3.5 bar absolute (page 409), so a pressure spike at that point means a clogged element. Examine the Axial Reciprocating Pump A10VO45 for wear, then work through the full troubleshooting sequence starting.
Manual Section: HydraulicsEngine overheating at full load, coolant temperature gauge climbing into red zone p. 35
Clean the rotary screen and cooler elements of all crop debris first; restricted airflow is the most common cause before any other diagnosis. Verify coolant level against the 65-liter system capacity (page 35). Inspect all hoses and seals for leaks. If temperature stays elevated after cleaning, pressure-test the cooling circuit for internal blockages before replacing the thermostat or water pump.
Manual Section: EngineExcessive grain loss through straw walkers, unclean sample in hopper during wet harvest p. 56
Adjust threshing drum speed within the 386-1,250 r.p.m. range (page 56) to match the crop. Work through the loss determination procedure to separate straw walker losses from cleaning losses before touching sieve or fan settings. Inspect grain pan rubber-metal connections for play; worn bushings let the pan drift and push grain into the tailings auger.
Manual Section: Cleaning UnitEngine won't start after sitting over winter, or rough idle with black smoke at throttle p. 76
Drain the water separator every 50 hours (page 76); water in the bowl is the most common hard-start cause after the machine has sat. Replace the fuel filter on the 240-hour schedule (page 64). Bleed the fuel system after any filter change. If rough running persists, inspect injector return lines for air entry points.
Manual Section: Fuel SystemThreshing drum vibrating or running rough, unusual noise from drum bearings during harvest p. 501
Remove the drum access panels and inspect beater bars for missing or cracked segments. Retorque fixing bolts to 110 Nm (page 501), then check shaft clamp sleeve studs at both bearing housings, torquing to 150 +30 Nm at the right (page 502) and left (page 503). Run the drum unloaded after reassembly and listen for any knock before cutting.
Manual Section: Threshing UnitFrequently Asked Questions
Torque specs for header drive bolts on CF 80 Cross Flow?
The tightening torque for the two hexagon head screws on the lower output shaft, which is part of the header drive, is 54 Nm. This is for clamping the drive disk to the profile with a flange on the shaft.
What are the replacement specifications for Engine fuel filter?
The engine fuel filter should be changed every 500 operating hours, or sooner if there is a noticeable drop in performance. The primary engine filter should also be replaced after every 500 hours of operation or if output drops.
What are the replacement specifications for Engine oil filter?
The engine oil and filter should be changed every 240 operating hours or once a year, whichever comes first. The oil capacity with a filter change is 21 liters.
Torque specifications for rotor bearings on CF 80 Cross Flow combine?
For the threshing drum shaft, the clamp sleeve for both the right and left bearings should be tightened with a stud torque of 150 +30 Nm. For the 3rd drum (separating drum), the stud torque is also 150 +30 Nm, and the two clamping screws at the drum body should be tightened with a torque of 70 Nm.
