Information Type:
Vehicle-specific, manufacturer-provided procedures and specifications.
Engine Type:
Diesel (Specific engine family not detailed in product info, but typical for Case IH tractors of this era would be Case IH 4-cylinder or 6-cylinder direct injection diesel engines, e.g., DT-354, DT-360).
Typical Horsepower Range:
Likely in the 60-90 HP range for the 1294/1394 models and potentially higher for the 1390, depending on specific engine configurations.
Torque Characteristics:
Designed for robust, consistent torque delivery for agricultural applications.
Fuel Delivery:
Likely mechanical injection pump (e.g., CAV, Bosch) with direct injection.
Cooling Method:
Pressurized liquid cooling system.
Oil Type And Capacity:
Requires specific diesel engine oil (e.g., API CD/CE or higher) and detailed capacity information would be found within the manual.
Gearbox Type:
Likely a synchronized constant mesh gearbox with multiple forward and reverse gears (e.g., 8 forward, 4 reverse or similar configurations).
Powershift Or Overspeed:
May feature a high-low range selector or a supplementary transmission for increased speed options (e.g., a 'Hi-Lo' or 'Trans-O-Matic' type system).
Pto Options:
Standard PTO (e.g., 540 RPM, potentially 1000 RPM) with engagement and maintenance procedures covered.
Differential Lock:
Typically includes a differential lock for enhanced traction, with operation and maintenance details in the manual.
Transmission Oil Type:
Requires specialized tractor hydraulic fluid (THF) or specified gear oil, with precise specifications in the manual.
Engine Oil Change Interval:
Typically 250 hours or annually, but specific recommendation will be in the manual.
Hydraulic Fluid Filter Change:
Regular intervals based on operating hours, detailed in the manual.
Engine Oil Specification:
API CD/CE or higher specification, SAE 15W-40 common for diesel engines of this era.
Hydraulic Transmission Fluid:
Case IH Hi-Tran, or equivalent universal tractor transmission fluid (UTTF) meeting specific specs.
Coolant Specification:
Ethylene glycol based coolant with appropriate anti-corrosion additives, mixed at 50/50 with distilled water.
Common Wear Points:
Potential wear on PTO clutch, hydraulic pump seals, and front axle components due to operational stress.
Electrical Gremlins:
Aging wiring harnesses or switches can lead to intermittent electrical issues, which the manual's schematics help diagnose.
Manufacturer History:
Case IH is a well-established brand in agricultural machinery, known for its robust and reliable tractors.
Series Context:
The 1294, 1390, and 1394 models represent a generation of utility and row-crop tractors from Case IH, known for their versatility and durability.
Production Era:
These models were likely produced during the late 1980s and early 1990s.
