Need the factory operating procedures for your Case IH 2400, 2500, or 2400 and 2500 'A' Series Industrial Tractors? This 140-page operator manual (OEM #1092877R7) covers the 454, 474, 475, 574, and 674 model range with variant-specific specs for each. Inside: a complete controls section walking you through the parking brake lever, differential lock, speed ratio control, and every dash indicator across hydrostatic and gear-drive variants. You also get a full fault tracing section covering hard starts, overheating, and hydrostatic drive faults, plus preventive maintenance schedules with cold and hot weather precautions, lubricant specs, and a full lubrication chart. Fill the hydrostatic system to 62 litres and confirm your hydraulic circuit holds at 175 kg/cm² (2500 lb/in²) before you load up. Every hour your tractor sits idle costs money. Bookmarked sections let you jump straight to fault tracing or maintenance schedules without paging through all 140 pages.

Case IH 454, 474, 574, 674 & 2400, 2500 Common Problems This Manual Covers
Case IH 454 fails to start or cranks slowly in cold weather despite having a good battery p. 112
Check the engine starting fault tracing guide on page 112. Verify the 95 amp h battery is fully charged and connections are tight. Inspect the fuel system for air leaks and ensure the 77 litres (17 gal) fuel tank has fresh winter-grade diesel.
Manual Section: Fault TracingTractor loses hydraulic lifting power midway through operation or attachments respond sluggishly under load p. 23
Inspect the general specifications on page 23. Verify the system maintains the rated working pressure of 175 kg/cm² (2500 lb/in²) during lifting. If the fluid is low, top off the 62 litres (14 gal) hydrostatic reservoir and check the filter for restrictions.
Manual Section: General SpecificationsEngine temperature gauge spikes into the red zone during heavy field work or constant PTO operation p. 25
Inspect the radiator fins for dirt accumulation and clean them thoroughly. Check the cooling system capacity for 3-cylinder models on page 25 to confirm it holds the full 11 litres (20 pints). Inspect the fan belt tension and check for coolant leaks.
Manual Section: General SpecificationsRear wheels slip under heavy draft loads or emit a clunking noise when engaging the transmission p. 24
Verify the rear wheel to axle torque specifications on page 24. Tighten all mounting hardware to 28.3 to 30.4 kgm (205 to 220 lbft) using a calibrated torque wrench. Check tyre pressures and adjust ballasting weights according to the preparation guidelines.
Manual Section: General SpecificationsFrequently Asked Questions
How do you check and adjust the engine clutch for gear drive machines on Case IH 454–674 and 2400/2500 tractors?
For gear drive machines, the engine clutch free travel should be adjusted to 25.4 mm (1 in.). Check this adjustment after the first 20 hours of operation and then every 200 hours thereafter. Refer to page 60 for the full adjustment procedure.
What is the total pedal travel specification for the starter isolation switch on Case IH gear drive tractors?
The movement for the starter isolation switch is specified as 1.25 mm (0.05 in) for gear drive machines as detailed on page 61. This measurement indicates the travel required to activate the switch and should be checked during clutch adjustment.
What are the fluid capacities for the Case IH 2400, 2500, 454, 474, 574, 674 tractor?
As specified on page 23: fuel tank holds 77 litres (17 gal); transmission fluid capacity is 34 litres (7.5 gal); hydrostatic fluid capacity is 62 litres (14 gal); cooling system capacity is 11 litres (20 pints). Confirm the hydraulic system holds at 175 kg/cm² (2500 lb/in²) working pressure before loading the tractor.
What is the rear wheel to axle torque specification for Case IH 454, 474, 574, 674 and 2400, 2500 tractors?
Torque rear wheel to axle bolts to 28.3 to 30.4 kgm (205 to 220 lb ft) as specified on page 24. Always check and re-torque after the first 50 hours of operation with new or re-installed wheels.
