Engine Type:
Gasoline (likely Continental or IH proprietary, specific displacement details would be in the manual).
Engine Configuration:
Likely a vertical shaft, single or twin-cylinder air-cooled gasoline engine. Specific model designation needed for precise details.
Horsepower Estimate:
Typically in the 10-15 HP range, but exact figure depends on engine model and tuning.
Torque Estimate:
Not readily available without specific engine model, but sufficient for light-duty agricultural tasks.
Fuel Delivery:
Carbureted, with gravity feed or a low-pressure fuel pump depending on exact configuration.
Ignition Type:
Magneto or breaker-point ignition system.
Cooling Method:
Air-cooled (primary method), though some larger variants may have had liquid cooling options. Manual will clarify for the 123.
Transmission Type:
Manual gearbox, likely a 3 or 4-speed transmission with a creeper gear option.
Differential Lock:
Often equipped with a differential lock for enhanced traction.
Drive System:
2WD (Rear Wheel Drive)
Power Take Off Pto:
Likely a belt-driven PTO, common for attaching implements like mowers.
Wheelbase Approximate:
Approximately 45-50 inches (varies slightly by tire size).
Length Approximate:
Approximately 60-70 inches.
Width Approximate:
Approximately 30-40 inches at the rear wheels.
Operating Weight Approximate:
Around 400-500 lbs, depending on attachments and fluids.
Safety Features Inherent:
Basic safety features typical of tractors of its era. Emphasis on operator awareness and proper use.
Operator Presence Control:
Likely not equipped with modern operator presence controls; relies on manual safety practices.
Braking System Type:
Drum brakes or external contracting band brakes, depending on specific sub-model/year.
Oil Change Interval:
Typically every 50-100 operating hours or annually, depending on severity of use. Specifics in manual.
Grease Points:
Regular lubrication of pivot points, steering components, and wheel bearings is critical. Schedule in manual.
Engine Oil Type:
SAE 30W or 10W-30 for gasoline engines, check manual for specific viscosity based on ambient temperature. API Service Classification 'SE' or higher.
Transmission Fluid:
Specific gear oil (e.g., 80W-90 GL-4) or IH Hy-Trans fluid. Manual is critical for correct specification.
Coolant Type:
For liquid-cooled variants (less common on 123, but possible), standard ethylene glycol antifreeze. Manual will specify ratio.
Common Wear Points:
Wear in steering components (tie rod ends, bushings), clutch wear, fuel system issues (carburetor gumming, fuel line degradation), electrical connections.
Engine Troubleshooting:
Carburetor adjustments, ignition timing, spark plug condition, compression issues are frequent concerns.
Spark Plug Gap:
Typically around 0.025 - 0.030 inches, but manual will provide exact specification and plug type.
Ignition Timing:
Critical for performance and fuel efficiency; manual will detail setting procedure using timing marks or a timing light.
Manufacturer Legacy:
International Harvester (IH) has a long-standing reputation for robust and reliable agricultural machinery and tractors.
