Engine Model Association:
The Case International 485 Tractor typically utilized a four-cylinder diesel engine from Case's proprietary range or licensed from manufacturers like Perkins. Specific engine models would require consultation of detailed specification sheets for the 485, but common configurations would be in the 3-4 liter displacement range. Examples of typical engines used in this era of Case tractors include the Case 4-390 or Perkins AD4.248, depending on the specific build year and market.
Horsepower Range Typical:
Estimated horsepower for the Case 485 Tractor typically falls in the 50-70 HP range, depending on the specific engine variant and tune.
Torque Specifications Typical:
Torque figures would vary by engine, but are generally optimized for agricultural applications, providing substantial pulling power.
Injection System:
Typically mechanical injection pump and injectors, specific make and model would be detailed in the manual.
Cooling Method:
Liquid-cooled
Transmission Type:
The Case International 485 Tractor often featured a manual transmission with multiple forward and reverse gears, sometimes including a synchronized gearbox for smoother shifting. Common configurations might be an 8-speed or 12-speed transmission. Power Take-Off (PTO) options would also be detailed.
Clutch Type:
Typically a dry, single-plate clutch.
Gear Selection Mechanisms:
Manual shift levers and possibly a synchronized gearbox.
Features:
As a utility tractor from its era, the 485 would not feature modern infotainment systems. Instrumentation would typically include essential gauges like oil pressure, coolant temperature, fuel level, and hour meter.
Features:
Driver assistance features are not applicable to this model. Focus is on mechanical and operational aspects.
Features:
No digital connectivity features.
Engine Oil Change Interval:
Typically every 250-500 operating hours, or annually, whichever comes first. Specific interval will be detailed in the manual.
Air Filter Replacement:
As needed based on operating conditions, or at recommended intervals (e.g., annually). The manual will provide guidance.
Fuel Filter Replacement:
Recommended at intervals like 250 or 500 hours, or when experiencing fuel system issues. The manual will specify.
Engine Oil Type:
Typically SAE 15W-40 or 10W-30 diesel engine oil, meeting API CD or CE specifications. Manual will confirm exact specification.
Transmission Hydraulic Fluid:
Often uses a universal tractor transmission oil (UTTO) or specialized hydraulic fluid compatible with Case transmissions and hydraulics. Manual will specify.
Coolant Type:
A mixture of antifreeze and water, typically a 50/50 mix of ethylene glycol-based antifreeze for freeze protection and corrosion inhibition. Manual will detail specific type and ratio.
Common Wear Items:
Common wear items on tractors of this era include clutch components, hydraulic pumps and seals, PTO splines, and fuel system components due to age and usage.
Electrical Reliability:
Older wiring harnesses can degrade over time, leading to intermittent electrical issues. The manual's electrical diagrams are crucial for diagnosis.
Manufacturer:
Case IH (International Harvester)
Product Line:
Part of Case's utility tractor lineup, the 485 represents a mid-size tractor designed for a wide range of agricultural tasks. It succeeded earlier models and was a precursor to later generations of Case IH tractors.
Production Period Estimated:
The 485 model series was produced in the 1970s and 1980s. Precise production years are not provided but would be specific to the manual's coverage.
