Manufacturer:
International Harvester (likely a derivative of their BD or DT series diesel engines, or a Continental engine in some markets).
Engine Type:
Diesel (likely naturally aspirated)
Displacement:
Approximately 154 cubic inches (2.5 Liters) for the D-179, but variations existed depending on specific configuration.
Bore X Stroke:
Specifics depend on engine variant, but common for the era's 3-4 cylinder diesels.
Horsepower Rated:
Around 45-55 PTO horsepower (exact figure varies by configuration and engine).
Torque Peak:
Not explicitly stated, but designed for strong low-end torque.
Injection System:
Direct injection (typical for IH diesels of this era), likely rotary or inline injection pump.
Engine Oil Change:
Typically every 50-100 operating hours, depending on operating conditions.
Fuel Filter Replacement:
As needed, or at recommended intervals (e.g., annually or every 250 hours).
Air Filter Service:
Regular checks and cleaning, replacement based on dust conditions.
Engine Oil:
API CD/CE rated diesel engine oil, SAE 15W-40 or 10W-30 depending on climate. Capacity around 5-6 quarts (4.7-5.7 liters) with filter.
Transmission Hydraulic Fluid:
IH Hytran or equivalent Universal Tractor Transmission Fluid (UTTF). Capacity around 10-12 gallons (38-45 liters) for transmission and hydraulics.
Coolant:
Ethylene glycol based antifreeze (50/50 mix with water) for freeze protection and corrosion inhibition.
Common Problems:
Potential for wear in transmission synchronizers, hydraulic pump wear, minor electrical gremlins, and aging seals/hoses. Overheating if cooling system maintenance is neglected.
Legacy:
International Harvester (IH) was a major American manufacturer of agricultural machinery, construction equipment, and vehicles.
Production Period:
Produced roughly from the late 1960s into the 1970s, succeeding earlier IH models.
Series:
Part of IH's smaller-to-mid-size tractor range, often positioned below the 464/544 series.
Manufacturing Locations:
Primarily manufactured in the United States (e.g., Rock Island, Illinois).
