Engine Type:
Typically 3 or 4-cylinder naturally aspirated diesel.
Horsepower Range:
Expected to be in the 40-60 HP range, depending on engine displacement.
Torque Curve Details:
The manual would provide specific torque figures and typical operating RPM ranges.
Injection System:
Likely indirect injection with rotary or inline injection pumps from manufacturers like Bosch or CAV.
Transmission Type:
Likely a constant mesh manual transmission with multiple forward and reverse gears (e.g., 8-speed or 16-speed synchromesh or non-synchromesh).
Power Take Off Pto:
Standard rear PTO, likely with multiple speeds (e.g., 540 RPM, 1000 RPM, or ground speed PTO).
Differential Lock:
Commonly equipped with a differential lock for enhanced traction.
Dashboard Features:
Basic instrumentation including fuel gauge, temperature gauge, oil pressure indicator, ammeter, and tachometer (if equipped).
Transmission Controls:
Manual gear shifter, clutch pedal, and potentially a range selector. PTO engagement lever.
Power Take Off Pto:
Mechanical PTO engagement for powering implements.
Engine Oil Change:
Typically every 100-250 operating hours, depending on operating conditions and oil type. Manual will specify exact interval and oil grade.
Air Filter Service:
Check and clean/replace as needed, especially in dusty conditions. Manual will provide specific intervals and procedures.
Fuel Filter Replacement:
Regular replacement is critical for diesel engines, typically every 250-500 hours. Manual specifies intervals and part numbers.
Hydraulic Fluid Change:
Typically every 500-1000 operating hours. Manual specifies type of fluid and replacement interval.
Engine Oil:
Likely SAE 30W or 10W-30 for diesel engines, meeting API CD or similar specifications. Manual will confirm exact specifications and capacities.
Hydraulic Fluid:
Typically a UTF (Universal Tractor Transmission Oil) or IH Hy-Trans fluid. Manual will specify the exact type and capacity.
Coolant:
A mixture of antifreeze and water, likely 50/50. Manual will specify type and capacity.
Common Wear Items:
Potential wear on clutch plates, brake components, hydraulic pump seals, and PTO bearings. Manual provides diagnostic steps for these.
Electrical System Concerns:
Older wiring harnesses can degrade, leading to intermittent electrical issues. The manual's wiring diagrams are crucial for diagnosis.
Engine Starting Problems:
Can be related to glow plugs, injection pump timing, fuel system leaks, or battery condition. Manual covers troubleshooting for each.
Manufacturer:
International Harvester (IH), a major American manufacturer of agricultural and construction equipment.
Production Era:
The 475 tractor was likely produced in the late 1960s and early 1970s, fitting into IH's range of utility tractors.
Manufacturing Locations:
Likely manufactured in various International Harvester plants within the United States.
