Engine Model Variations:
Likely equipped with International Harvester's own diesel engines, potentially including variants like the D-354 or D-360 depending on the specific configuration (e.g., row crop vs. standard).
Horsepower Range:
Typically in the 60-75 PTO horsepower range, depending on the specific engine and transmission configuration.
Torque Specifications:
Specific torque figures for engine components (e.g., cylinder head bolts) will be detailed in the manual.
Injection System:
Likely Bosch inline injection pumps or similar mechanical fuel injection systems.
Transmission Type:
Likely a 7-speed synchronized transmission (e.g., 6 forward speeds + 1 reverse), often referred to as a 'gear drive' transmission.
Torque Amplifier:
The '1026' designation often implies the presence of a Torque Amplifier (TA) unit, which provides a lower gear range for increased torque, effectively doubling the gear ratios.
Clutch Type:
Dual-clutch system is common for tractors with a Torque Amplifier, allowing PTO operation while shifting gears.
Engine Oil Change Interval:
Typically every 100-200 operating hours for diesel engines of this era, depending on operating conditions. Manual will specify exact interval and oil type.
Hydraulic Fluid Change Interval:
Generally every 500-1000 operating hours. Manual will detail the type and capacity.
Engine Oil Specification:
Likely requires a diesel engine oil meeting API CD or higher classification, with viscosity grades such as 15W-40 or 20W-50, depending on ambient temperature. Manual will confirm.
Hydraulic Fluid Specification:
Typically IH Hy-Trans fluid or a comparable universal tractor transmission oil (UTTO) meeting specific IH specifications. Manual will specify.
Common Wear Items:
Typical issues might include clutch wear, Torque Amplifier problems, hydraulic system leaks, and engine component wear over time, all of which the manual will address.
Electrical System Reliability:
Wiring harnesses and connections can degrade over time; the manual's wiring diagrams are crucial for troubleshooting.
