Part of the Case Repair Manuals.
This is the complete Case IH factory service manual for the Magnum 250, 280, 310, 340, and 380 tractors and the Magnum 310, 340, and 380 Rowtrac tracked variants. It is organized into the standard Case IH system groups, Engine, Power Coupling, Transmission, Four-Wheel Drive, Front and Rear Axles, PTO, Brakes, Hydraulic Systems, Hitches and Drawbars, Steering, Wheels, Tracks and Track Suspension, Cab Climate Control, Electrical Systems, and Platform and Cab. Each group carries specifications, troubleshooting, and step-by-step removal, disassembly, inspection, assembly, and installation procedures for these Tier 4 Final machines, including the 9.0 litre diesel with SCR/DEF, the continuously variable transmission, and the Rowtrac undercarriage.

Case IH Magnum 250–380 Common Problems This Manual Covers
CVT transmission overheating or erratic shifting under heavy draft loads
Follow the Transmission group. Confirm the transmission and hydraulic oil level and the CVT oil filter condition first, since sustained deep-tillage loads raise oil temperature and a low level or clogged filter compounds it, then run the control-system diagnostics and pressure checks against the specifications before disassembly.
Manual Section: TransmissionRowtrac track undercarriage wear or failure, especially after extended road travel
Use the Tracks and track suspension group. Inspect the idlers, rollers, and track tension and service the idler and roller hubs with the specified oil at the called-out intervals. The narrow-track undercarriage wears faster on the road, so keep tension in spec and inspect the rollers and idlers for early wear.
Manual Section: Tracks and track suspensionWeak or failed hydraulic lift when engaging a front weight or implement
Use the Hydraulic systems and Hitches groups. Check the variable displacement pump and remote-valve pressures against spec, and inspect the hitch linkage and fasteners for over-tightening or wear before replacing hydraulic components, since a linkage or pressure fault often mimics a failed cylinder.
Manual Section: Hydraulic systemsFrequently Asked Questions
The CVT transmission is overheating or shifting erratically under load. Where do I look?
Go to the Transmission group, which covers the continuously variable transmission and its external controls. Check the transmission and hydraulic oil level and the CVT oil filter first, since heavy draft loads like deep tillage drive up temperature, then use the control-system diagnostics and pressure checks against spec before opening the transmission.
What track undercarriage service does this cover for the Rowtrac models?
The Tracks and track suspension group covers the Rowtrac undercarriage, including the idlers, rollers, and track tension, with the idler and roller hub lubrication specifications. The narrow-track undercarriage wears faster during extended road travel, so follow the inspection and tensioning procedures at the intervals the manual calls out.
Which engine and emissions system is on these Magnums?
These are Tier 4 Final Case IH Magnum tractors with a 9.0 litre diesel and SCR/DEF aftertreatment, and the manual covers the engine and crankcase, lubrication, cooling, fuel injection, and the DEF system. The DEF (AdBlue) tank holds 87 litres (23 US gallons); use the specified fluids and intervals in the specifications.
What are the main fluid capacities?
Engine oil is 25 litres (6.6 US gallons) without a filter change, the transmission and hydraulic system with Case IH Akcela Hy-Tran holds 172 litres (45.5 US gallons) on a wheeled powershift with the standard rear axle, the MFD front axle differential holds 11 litres, the front PTO 4.2 litres, the DEF tank 87 litres, and the fuel tank 636 litres (168 US gallons) on rear-wheel tractors.
The hydraulic lift or three-point hitch is weak or fails with a front weight or implement. What should I check?
Use the Hydraulic systems group and the Hitches, drawbars, and implement couplings group. Check the variable displacement pump and remote-valve pressures against spec, and inspect the hitch linkage and its fasteners, since over-tightened or worn lift components are a common cause. Verify pressures before replacing valves or cylinders.
