Case IH Farmall 115C Common Problems This Manual Covers
Case IH Farmall 115C brake pedals feel soft or travel too far when engine is running p. 216
Check the hydraulic brake fluid level first. Inspect both brake pedals for equal resistance — uneven travel indicates one circuit needs attention. Review the brake troubleshooting steps on page 216: excessive pedal travel with the engine running points to air in the system or a fluid leak at the wheel cylinder. Confirm the transmission/rear axle hydraulic reservoir is at the correct level (capacity: 58 l / 15.3 US gal).
Manual Section: Hydraulic service brakes - TroubleshootingWarning light or alarm appears on the display panel during startup or field work p. 219
Do not ignore a flashing warning — stop the tractor safely and check the display warnings overview starting on page 219. Each warning has a corrective action listed there. If an error code appears on the instrument cluster, cross-reference it on page 225 for the specific fault code, its function, and whether an audible alarm accompanies it. For hydraulic lift, transmission, or PTO fault codes, check the symptom table on page 223.
Manual Section: Display warnings overviewRemote hydraulic flow feels sluggish or implements respond slower than expected p. 214
Verify the hydraulic system oil level in the transmission/rear axle reservoir — capacity is 58 l (15.3 US gal). Check the hydraulic circuit oil filter condition per the maintenance schedule on page 155. Inspect all remote valve couplers for proper connection and make sure the remote control valve is fully engaged. If the system still underperforms, review the hydraulic system troubleshooting chart on page 214 for remote control valve and pump failure symptoms.
Manual Section: Hydraulic systems - Troubleshooting HYDRAULIC SYSTEMEngine hard to start in cold weather or cranks slowly without firing p. 211
Check the battery charge level and terminal connections for corrosion — cold cranking performance drops sharply with a weak battery. Verify fuel level and that the fuel shutoff is fully open. Consult the engine troubleshooting chart on page 211 for difficulty-starting and no-start conditions. If the starter cranks slowly, also check the electrical troubleshooting section on page 213, which covers low starter motor speed and battery charge issues.
Manual Section: TROUBLESHOOTING ENGINEGear shifting is stiff or grinds when moving through mechanical shuttle transmission p. 91
With the engine running and tractor stationary, depress the clutch pedal fully before attempting any shift. Verify you are following the correct shift sequence from the 12x12 transmission speed table in the operating instructions on page 91. Check transmission oil level — the rear axle/transmission system holds 58 l (15.3 US gal). If difficulty persists in specific ranges, note the exact gear position and check page 223 for GEAR-SHIFT fault codes logged by the display.
Manual Section: Operating InstructionsDPF warning light illuminated on dashboard, engine power feels reduced p. 219
Check the display warning on page 219 for the DPF indicator and its required corrective action — the tractor may request a parked regeneration cycle. Do not continue heavy field work until the regeneration completes. The DPF has a scheduled maintenance interval of every 3000 hours (page 190). If the warning clears after regeneration but returns quickly, inspect the air filter and engine oil level (capacity: 8.5 l / 2 US gal) before returning to work.
Manual Section: Display warnings overviewFrequently Asked Questions
What are the common error codes for Case IH Farmall 115C?
The manual lists various fault codes for the digital instrument, including 3786 for inhibited DPF automatic regeneration, 14001 for rear power take-off shorted to Vcc or open circuit, and 14200 for battery isolator switch on at key-on for more than 30 seconds. These codes are accompanied by audible warnings and/or warning lights.
How to reset service indicator Farmall 115C
To reset the oil change counter, which acts as a service indicator, press and hold switch (2) on symbol (B) for more than three seconds to enter the programming menu. Navigate to "OIL RESET" S1 using switch (3) on symbol (D), then press switch (2) on symbol (B) to display "RESET" and again to reset the hour meter. The monitor will display "OFF" and the engine oil pressure warning light will blink for two seconds if reset correctly.
