Engine Manufacturer:
International Harvester
Engine Type:
Diesel (most common for 1026, though gasoline variants may exist for some tractor lines)
Displacement:
Typically around 310 cubic inches (5.1L) for IH D-310 diesel engine, commonly found in this tractor series. Specific engine variant may vary. Consult manual for exact specs.
Horsepower Rating:
PTO horsepower typically in the range of 70-80 HP. Drawbar horsepower will be slightly lower. Exact figures depend on engine tuning and transmission.
Torque Output:
Specific torque figures vary by engine variant and RPM. Consult manual for precise specifications.
Injection System:
Direct Injection (typical for IH diesel engines of this era)
Transmission Type:
Manual transmission with synchronized gears or a PowerShift transmission (e.g., International Harvester's own design). Specific availability depends on the 1026 variant.
Optional Transmission:
PowerShift or enhanced manual transmission options may have been available.
Gear Configurations:
Multiple forward and reverse gears. The exact number of gears (e.g., 8 forward, 4 reverse in a manual) is detailed in the manual.
Wheelbase:
Varies by configuration (e.g., standard row crop, utility). Typical range might be around 80-90 inches. Consult manual for exact dimensions.
Operating Weight:
Approximate operating weight often in the 7,000-8,500 lbs range, depending on configuration and ballast. Manual will provide precise figures.
Infotainment System:
N/A (Basic tractor instrumentation: fuel gauge, temperature gauge, oil pressure light/gauge, ammeter).
Driver Assistance Features:
N/A (Focus on mechanical operation and driver control).
Connectivity Options:
N/A
Engine Oil Change Interval:
Typically every 100-200 operating hours, or annually. Manual will specify exact interval and oil type.
Hydraulic Fluid Change Interval:
Usually every 500-1000 operating hours. Manual will detail the specific fluid and filter replacement schedule.
Engine Oil Type:
API Service Classification CD or CE equivalent diesel engine oil, with appropriate viscosity grade (e.g., 15W-40 or 10W-30 based on ambient temperature). Consult manual for specific IH-approved oils.
Hydraulic Fluid Type:
IH Hy-Trans fluid or equivalent universal tractor transmission fluid (UTTF) meeting IH specifications. Manual will provide the exact specification (e.g., Specification H-346).
Transmission Fluid Type:
Depending on transmission type (manual or PowerShift), specific gear oil or UTTF will be required. Manual is crucial for this specification.
Coolant Type:
Ethylene glycol-based antifreeze mixed with distilled water in a 50/50 ratio. Manual will specify the correct type and freeze protection.
Common Wear Items:
Hydraulic pump wear, clutch wear, front axle kingpin wear, and potential for diesel injection pump issues are common for tractors of this age. The manual will guide on inspection and repair.
Electrical System Quirks:
Wiring harness degradation, switch failures, and starter issues can be prevalent. Detailed wiring diagrams in the manual are essential for troubleshooting.
Manufacturer Legacy:
International Harvester (IH) has a long and storied history in agricultural machinery, known for its robust and reliable tractors.
Tractor Series:
The 1026 is part of IH's strong lineup of medium-frame tractors, often featuring advancements in engine technology and operator comfort for its era.
Production Period:
The 1026 model was likely produced in the late 1960s to early 1970s, bridging the gap between earlier models and the newer 56 series. Specific production years will be within the manual.
