Diagram Clarity:
High-quality diagrams are critical for a parts catalog to ensure accurate part identification.
Binding Type Physical:
If physical, likely a durable binding suitable for workshop use (e.g., spiral bound, perfect bound).
Paper Type Physical:
If physical, likely durable paper stock resistant to grease and moisture.
Engine Family:
Likely utilized engines from the International Harvester BD or D series (e.g., BD-154, BD-206, or D-236/240 variants depending on specific configurations and regional markets).
Engine Displacement Range:
Typically 154 to 240 cubic inches (approx. 2.5 to 4.0 liters), depending on the specific engine variant.
Engine Type:
Typically 3 or 4-cylinder naturally aspirated diesel engines.
Horsepower Range:
Approximate horsepower output would range from 40 to 65 PTO horsepower, depending on engine and transmission configuration.
Injection Type:
Mechanical direct injection or indirect injection, typically utilizing rotary or inline fuel injection pumps.
Engine Oil Change Interval:
Typically every 250-500 operating hours, or annually, depending on operating conditions and oil specification.
Transmission Fluid Change Interval:
Generally every 1000-1500 operating hours, or as specified in specific service bulletins.
Hydraulic Fluid Change Interval:
Typically every 1000-1500 operating hours, with filter changes at more frequent intervals.
Engine Oil Specification:
API CD or higher, SAE 10W-30 or 15W-40 diesel engine oil recommended. Check manual for exact viscosity based on ambient temperature.
Transmission Hydraulic Fluid Type:
IH Hy-Trans fluid or equivalent UTF (Universal Tractor Transmission Fluid) meeting Caterpillar TO-2 specifications is typically required for the transmission, final drives, and hydraulics.
Coolant Specification:
Ethylene glycol based antifreeze with corrosion inhibitors, typically a 50/50 mix with distilled water.
Clutch Wear:
Clutch wear is a common maintenance item due to the nature of tractor operation; requires periodic adjustment or replacement.
Hydraulic Pump Seals:
Seal leaks in the hydraulic pump or lift cylinders can occur over time and require seal kit replacement.
Electrical Connections:
Corrosion or loosening of electrical connections, especially in the wiring harness and at the battery terminals, can lead to intermittent issues.
Injector Pump Timing:
Fuel injection pump timing may need to be checked and adjusted periodically for optimal performance and fuel efficiency.
