Specifications:
Detailed specifications are provided.
Torque Specifications:
Essential torque specifications for all critical fasteners, crucial for proper assembly and preventing component failure.
Clearance Settings:
Specifications for valve lash, bearing clearances, and other critical operating clearances.
Engine Options:
The 826 series typically featured International Harvester's own diesel engines, often a 360 or 414 cubic inch inline-six diesel. Gas engine options were also available depending on the specific variant and market. Specific engine codes would be detailed within the manual.
Horsepower Torque:
Detailed horsepower and torque figures for various engine configurations would be found within the manual, essential for performance diagnostics and tuning.
Fuel Delivery:
Covered in detail, likely including diesel injection pumps (e.g., CAV, Bosch), fuel filters, lines, and carburetor specifications for gasoline models.
Internal Components:
Procedures for cylinder head, pistons, crankshaft, camshaft, timing gears/chains, oil pump, and cooling system are expected.
Ignition Starting:
Details on starter motors, ignition coils (for gas), distributors, spark plugs, and battery charging systems.
Transmission Type:
The 826 was known for offering a robust manual transmission, likely a 8-speed or 16-speed syncromesh gearbox. Power steering and powershift transmission (Torque Amplifier or fully powershift) were often optional, and these would be detailed.
Powershift Options:
Details on the optional Torque Amplifier (TA) system, which provided on-the-fly range changes, and potentially a fully automatic powershift transmission would be covered.
Fluid Requirements:
Specific recommendations for transmission fluid types and capacities, critical for longevity and proper operation of both manual and powershift units.
Dimensions General:
While exact dimensions vary by configuration (2WD/4WD, tire size), the manual would provide critical measurements for clearance, maintenance access, and component fitting.
Weight Specifications:
Information on operating weights, shipping weights, and potentially ballast recommendations would be present for stability and traction analysis.
Safety Standards:
As a tractor, safety ratings would pertain to operational stability, ROPS (Roll Over Protective Structure) compatibility, and PTO guarding, all of which would be discussed in maintenance and operation sections.
Braking System Design:
Details on the hydraulic brake system, including master cylinder, wheel cylinders, brake discs/drums, and adjustment procedures for safe stopping.
Operator Station:
Information pertaining to the operator's station, seating, and controls to ensure safe operation.
Infotainment Features:
As a tractor from the late 1960s/early 1970s, infotainment features are absent. The focus is purely on mechanical and operational functionality.
Assistance Systems:
No electronic driver assistance systems. Primary operational aids would be the power steering system and the optional Torque Amplifier transmission.
Connectivity Features:
No electronic connectivity features. The focus is on direct mechanical and hydraulic controls.
Engine Oil Change:
Typical intervals for engine oil and filter changes would be specified, likely in the range of 100-250 operating hours, depending on operating conditions and oil type. For example, 100 hours for severe duty, 250 for normal.
Hydraulic Fluid Change:
Recommended intervals for hydraulic fluid and filter replacement, crucial for the operation of PTO, hitch, and steering. This could be around 500-1000 operating hours.
Engine Oil Type:
Specification for engine oil, likely a heavy-duty diesel engine oil, such as API CD or CE classification, with recommended viscosity grades like 15W-40 or 30W depending on ambient temperatures.
Hydraulic Fluid Type:
Specification for hydraulic/transmission fluid. For IH tractors of this era, this would typically be IH Hy-Tran fluid or an equivalent specification, designed to handle shared lubrication and hydraulic functions.
Common Wear Points:
The manual would detail maintenance for common wear points such as clutch wear, PTO spline wear, steering component wear, and hydraulic system leaks.
Engine Longevity:
Guidance on preventing common engine issues like overheating, fuel system contamination, and improper lubrication would be provided.
Transmission Problems:
Troubleshooting common transmission issues like hard shifting, clutch slippage, or problems with the Torque Amplifier engagement.
Manufacturer Legacy:
International Harvester (IH) was a major American manufacturer of agricultural machinery, construction equipment, and vehicles. The 826 represents a significant model in their tractor lineage.
826 Positioning:
The 826 was part of IH's late 1960s and early 1970s tractor lineup, offering a balance of power and features for medium to heavy-duty farm work. It often succeeded or complemented models like the 706 and preceded models like the 886.
Production Period:
The 826 was primarily produced from 1969 to 1971, though variations might extend slightly.
