Need the factory operating guide for your Case IH Farmall 40B CVT, Farmall 45B CVT, or Farmall 50B CVT compact tractor? This 266-page operator manual (OEM #48028211) is the official factory reference written for the owner, not the service shop. You get a thorough controls and instruments walkthrough, a maintenance chart broken by interval from daily checks through every 200 hours, and a troubleshooting section backed by error code tables so that dashboard warning tells you something useful instead of just ruining your morning. Operating instructions, transport procedures, and a complete specifications section are all inside. The CVT transmission takes 35.2 l (9.3 US gal) of fluid; drain and refill at 300 hours, check the level every 50. Every hour your tractor sits costs money. Bookmarks jump you straight to any section; search any spec by keyword and get back to work.

Case IH Farmall 40B/45B/50B CVT Common Problems This Manual Covers
Farmall 40B CVT, 45B CVT, or 50B CVT driveline temperature warning light on during operation, tractor slows or loses drive p. 68
Stop immediately and let the transmission cool. Check the driveline fluid level per the procedure on page 181 — inspect monthly or every 50 hours. If the amber light triggered, oil reached 100 °C (212 °F); red means at or above 107 °C (225 °F). Verify the transmission, rear axle, and hydraulic system holds 35.2 l (9.3 US gal) total capacity. Change the fluid every 300 hours as shown on page 195.
Manual Section: Controls and InstrumentsEngine won't start after fuel filter replacement, cranks but no fuel delivery
Bleed trapped air from the fuel system using the procedure on . Work the hand primer until you feel firm resistance and no bubbles escape from the bleed point. Drain the fuel filter bowl every 100 hours (page 186) and replace the filter after the first 50 hours, then every 300 hours thereafter (page 170). If cranking still produces no start, check the fuel sensor connector for moisture or corrosion at the filter housing.
Manual Section: MaintenanceHydraulic warning light on or implements respond slowly during heavy loader work
Check fault codes on — code H03 indicates hydraulic pressure low. Verify the hydraulic oil filter is not overdue: replace it after the first 50 hours, then every 300 hours (page 196). Confirm total system oil level is correct at 35.2 l (9.3 US gal) with the tractor on level ground. System relief is set at 17160 kPa (2489 psi); if the indicator shows pressure below 1800 kPa (260 psi), park the tractor and contact your dealer before continuing use.
Manual Section: Controls and InstrumentsCVT speed limited to crawl in cold weather, tractor won't reach normal transport speed p. 127
This is normal cold-weather behavior. Below -5 °C (23 °F), the CVT limits travel to 7 km/h (4.3 mph) to protect the transmission while oil warms up. Between -5 and 10 °C (23–50 °F), maximum speed increases gradually from 7 km/h up to 30 km/h (18.6 mph) as oil temperature rises. Refer to the cold-start speed table on page 127. Allow adequate warm-up time at low load before demanding full speed.
Manual Section: Operating InstructionsEngine overheats, coolant temperature warning on, radiator cap leaking or releasing steam p. 207
Stop the engine and let it cool completely before removing the radiator cap. Inspect the cap — it holds 0.9 bar (13 psi) per the specification on page 237; a cap that releases below that pressure must be replaced. Check coolant level and top up as needed. Drain, flush, and refill the cooling system every season or per the maintenance chart; the Farmall 40B coolant system takes 9.0 l (9.6 US qt) (page 207). Inspect hoses and clamps for seepage while you have the hood open.
Manual Section: MaintenanceTransmission fault code displayed on instrument cluster, tractor enters limp or restricted mode
Note the fault code shown on the ADIC display and look it up in the reference table starting. Code T05 signals CVT overheating; code F01 points to the fuel system sensor. For transmission codes, check the fluid level at the sight glass (every 50 hours, page 181) and confirm the transmission pressure filter is not overdue at 300 hours (page 197). Clear the code, cycle the ignition, and monitor for recurrence. If the code returns after a fluid check, contact your Case IH dealer with the exact code number.
Manual Section: Controls and InstrumentsFrequently Asked Questions
How to reset error code on CASE IH Farmall 40B CVT with CVT?
The manual states that fault codes, including those related to the CVT, will continue to appear on the ADIC (Analog Digital Instrument Cluster) until they are removed by a Case IH Dealer. There is no procedure provided for the operator to reset these error codes.
Torque specs for engine bolts on CASE IH Farmall 40B CVT 2.5L diesel engine?
The manual provides minimum tightening torques for general metric non-flanged and flanged hardware, including bolt classes 8.8 and 10.9, and sizes from M4 to M24. For example, an M10 Class 8.8 unplated bolt requires 37 N·m (27 lb ft) of torque. However, it does not specify torque values specifically for "engine bolts" of a "2.5L diesel engine".
What are the common error codes and how to clear them on CASE IH Farmall 40B CVT?
The manual lists common error codes displayed on the ADIC, such as codes for "Forward and Reverse clutches not calibrated" and "Dump valve 12 V circuit". However, it explicitly states that these fault codes will continue to appear until removed by a Case IH Dealer, indicating no operator-level clearing procedure.
How to reset hydraulic system error on CASE IH Farmall 40B CVT
The manual lists fault codes displayed on the ADIC, some of which are indirectly related to hydraulic system performance, such as "Driveline/Steering oil pressure too low, below 1800 kPa (260 psi)". For such issues, the recommended action is to "Check power steering pump and CVT clutch pressure. (Contact your CASE IH dealer.)". The manual does not provide an operator-level procedure to reset hydraulic system errors.
What are the replacement specifications for Fuel filter?
The diesel fuel filter should be changed after the first 50 hours of operation, and then following every 300 operating hours thereafter. The procedure involves unscrewing the retaining nut, removing the filter element, inspecting O-rings, installing a new element, and bleeding the fuel system.
