All 296 pages of this Case IH Farmall 45C, Farmall 55C Operator Manual (OEM #48115974) focus on keeping your 2017–2018 compact tractor operating safely and on schedule. Inside: a thorough safety section covering ROPS fold-down procedures, safe startup and shutdown sequences, and every cab and ROPS warning sign, plus a controls chapter that maps each instrument panel indicator, engine fault code display, DPF switch, and PTO operation. Your maintenance chapter runs from every-10-hour daily checks through 500-hour service intervals, backed by fluid capacities, consumables specs, and a troubleshooting symptom guide for when something acts up. Fill the crankcase to 5.5 L (5.8 US qt) after an oil and filter change; once temperatures drop below -7 °C (19 °F), the specs call for No. 1-Diesel at a minimum cetane rating of 45. No more guessing what the dashboard is telling you. Bookmarked for instant navigation: open it on your tablet, jump straight to the right section, and get back in the seat.

Case IH FARMALL 45C, FARMALL 55C Common Problems This Manual Covers
Case IH Farmall 45C/55C engine warning light on, tractor shuts down below -5°C with error code
Check the error code reference to identify the fault. If temperatures are below -7°C (19°F), switch to No. 1-Diesel fuel with a minimum Cetane rating of 45, per page 273. Verify the coolant immersion heater is plugged in — it activates at -17.7°C (0°F) per page 158. Inspect the battery connections for corrosion and confirm the battery holds charge before attempting a cold restart.
Manual Section: Controls and InstrumentsDPF regeneration warning active, engine power limited or tractor won't return to full throttle p. 137
Do not shut the engine off when the DPF regeneration indicator is lit. Find a safe open area, keep engine load light, and allow regeneration to complete — it runs 15 to 25 minutes per page 137. Avoid short idling cycles that interrupt the process. If the light returns within hours of a completed cycle, consult the troubleshooting procedures on page 267 under engine exhaust and low power symptoms.
Manual Section: Operating InstructionsEngine starts but runs rough, emits black exhaust smoke under load during field work p. 267
Check the air filter restriction indicator on the dashboard before assuming a fuel issue. Verify the fuel tank is not below the low mark — cab models hold 47 L (12.4 US gal), ROPS models hold 40 L (11 US gal) per page 211. Review the engine troubleshooting chart on page 267 under excessive exhaust smoke and low power. If symptoms persist after confirming clean air and adequate fuel, schedule a dealer inspection of the EGR system.
Manual Section: TroubleshootingThree-point linkage won't raise implement or raises very slowly at full throttle p. 268
Verify the transmission, rear axle, and hydraulics fluid level — capacity is 43 L (11.4 US gal) per page 211. Check that the external hydraulic lift control lever is fully in the raise position and not obstructed. Inspect around the rear linkage for visible oil leakage. Refer to the hydraulic lift system troubleshooting chart on page 268 for a step-by-step symptom checklist before calling a dealer.
Manual Section: TroubleshootingBrake pedal feels spongy or one side drags, uneven stopping during transport p. 268
Check brake pedal free play — the correct range is 50.0 to 60.0 mm (1.96 to 2.36 in) per page 226. If free play is outside this range, do not operate the tractor on road until adjusted. Lock both brake pedals together before any road transport. Inspect the brake area for oil contamination or visible leakage. See the mechanical service brakes troubleshooting chart on page 268 for uneven braking and pedal-return symptoms.
Manual Section: TroubleshootingBattery not charging, headlights dim at idle, electrical accessories intermittently fail p. 270
Check that belt tension on the alternator drive is firm and the alternator output connector is seated. The alternator is rated at 70 A per page 273 — at low idle (850 RPM) charging output will be reduced, so do not judge charging by idle-speed voltage alone. Inspect the battery terminals for corrosion and verify cable ground connections at the chassis. Use the electrical system troubleshooting chart on page 270 for battery-not-charging and dim-headlights diagnosis steps.
Manual Section: TroubleshootingFrequently Asked Questions
How to reset error codes on Case IH Farmall 45C?
The manual does not provide instructions on how to reset error codes. It advises contacting an authorized CASE IH dealer to report the fault code displayed for correction, as indicated in the 'Engine fault code display' section on page 3-11.
What are the torque specs for Case IH Farmall 55C engine bolts?
The manual does not provide torque specifications for engine bolts. It only specifies torque for front and rear wheel bolts and nuts as 176 – 196 N·m (130 – 145 lb ft), as detailed on page 7-21.
How to reset the DPF regeneration interval on Case IH Farmall 45C?
The manual describes automatic, inhibited, and forced DPF regeneration modes, but it does not provide instructions on how to reset the DPF regeneration interval. Regeneration is initiated automatically when the soot load reaches 100% or can be forced manually by pressing the upper side (B) of the DPF switch (3) for approximately three seconds, as described on page 4-5.
How to reset the transmission fault light on Case IH Farmall 45C?
The manual does not provide specific instructions on how to reset a 'transmission fault light'. The troubleshooting section lists various transmission-related issues and their corrections, but no general fault light reset procedure is mentioned.
What are the replacement specifications for Diesel Particulate Filter (DPF)?
The manual states that if the Diesel Particulate Filter (DPF) is damaged to an extent that requires replacement due to ignored or interrupted regeneration notifications, it must be replaced by an authorized CASE IH dealer. However, specific replacement specifications (e.g., part number, dimensions) for the DPF itself are not provided.
