Case IH Farmall 110A–140A Common Problems This Manual Covers
Case IH Farmall tractor engine cranks but won't start or fires and immediately dies p. 247
Verify the gearshift is fully in neutral and the clutch pedal is depressed before each start attempt. If the starter motor turns sluggishly, check battery terminal connections for corrosion. Once running, confirm engine low idle settles to 800 RPM (page 256). For the complete no-start diagnostic sequence, refer to page 247.
Manual Section: TroubleshootingHydraulic remote valves move implements slowly or lose lift pressure during field operation p. 249
Check hydraulic oil level at the sight glass before starting work. Operate at 2200 RPM engine speed (page 256) for maximum flow through remote circuits. If valves still respond sluggishly, verify the control detents release fully and check the hydraulic filter service interval. Refer to page 249 for the complete remote valve troubleshooting steps.
Manual Section: Hydraulic Remote Control ValvesClutch slips or chatters under heavy loader work or when pulling hard uphill p. 171
Shift to a lower gear before climbing grades or engaging heavy implements rather than slipping the clutch to maintain speed. Avoid resting your foot on the pedal during field passes. Run the engine toward rated 2200 RPM (page 256) during loader cycles rather than lugging it. Review proper loader technique guidelines on page 171.
Manual Section: Working OperationsTransmission temperature warning flashes or transmission runs hot during prolonged heavy operation p. 248
Stop field work and idle the engine at 800 RPM (page 256) for several minutes before shutdown to dissipate heat. Check transmission oil level and confirm the oil grade matches specifications on page 183. Avoid sustained operation in too high a gear under full load. Refer to page 248 for the transmission overheating troubleshooting chart.
Manual Section: TransmissionRed warning indicator stays lit on the instrument panel during normal tractor operation p. 55
Identify the warning symbol using the indicator reference key in the Controls and Instruments section starting page 55. Never operate with an unidentified red indicator active. Check engine oil at the dipstick and coolant at the reservoir. If a brake circuit warning appears, verify brake fluid is within the 1.0-1.5 l range specified on page 183.
Manual Section: Controls and InstrumentsFrequently Asked Questions
What are the recommended service intervals?
The manual provides a detailed maintenance chart with recommended service intervals. For instance, the engine oil level should be checked every 10 hours or daily, tire pressure every 50 hours, and engine oil and filter every 300 hours. Transmission oil should be serviced every 1200 hours or annually, while the engine cooling system requires attention every 3600 hours or four years.
What fluids and capacities does this machine require?
The machine requires specific fluids and capacities depending on the model. For Farmall 110A/120A, the fuel tank capacity is 150 l (39.6 US gal) and engine oil capacity is 11 l (2.9 US gal). For Farmall 125A/140A, the fuel tank capacity is 235 l (62.1 US gal) and engine oil capacity is 14 l (3.7 US gal). The preferred engine oil is CASE IH AKCELA ENGINE OIL 15W-40, and for transmission/hydraulic systems, CASE IH AKCELA NEXPLORE™ FLUID is recommended.
How to troubleshoot engine won't start?
To troubleshoot an engine that won't start or is difficult to start, first check for an incorrect starting procedure. Verify the fuel level, bleed the fuel system if air is present, and ensure the correct engine oil viscosity and fuel type for the ambient temperature are used. If the fuel system is contaminated or the fuel filter is clogged, clean or replace them accordingly. For fuel injector faults, contact your dealer.
What are the hydraulic system specifications?
The hydraulic system uses a gear pump with fixed displacement. The flow at an engine speed of 2200 RPM varies by model, with some having 49 l/min (12.9 US gpm) and others 35 l/min (9.3 US gpm) or 76 L (20 US gal). The relief valve setting is typically between 14755 - 16272 kPa (2140 - 2360 psi) or 16800 - 17200 kPa (2437 - 2495 psi) depending on the model.
What torque specifications are listed?
The manual provides detailed torque specifications for both metric hex head (non-flange) and metric flange head hardware. For example, a Class 8.8 M4 bolt (non-flange) requires 3.5 N·m (31 lb in), and a Class 10.9 M24 bolt (non-flange) requires 1195 N·m (882 lb ft). For flange head hardware, a Class 8.8 M4 bolt requires 3.8 N·m (34 lb in), and a Class 10.9 M24 bolt requires 1447 N·m (1067 lb ft).
