Engine Type:
Diesel (likely, common for Nuffield tractors of this era)
Engine Configuration:
Likely 2, 3, or 4 cylinder, naturally aspirated
Bore Stroke:
Specific details require model year identification, but typical for BMC engines of the period
Horsepower Range:
Typically 15-35 HP for 'Mini' tractors of this era, depends on specific model variant
Torque Output:
Specific details require model year identification, but designed for low-end torque
Injection System:
Likely indirect injection via rotary or inline injection pump
Engine Oil Change:
Typically 100-250 hours or annually, dependent on oil type and operating conditions
Hydraulic Fluid Change:
Typically annually or after a specified number of operating hours
Air Filter Service:
Frequent checks and cleaning/replacement depending on dust levels
Engine Oil Specification:
Likely SAE 30 or 10W/30 Diesel engine oil, meeting API CD or similar specification
Hydraulic Fluid Specification:
Likely Universal Tractor Transmission Oil (UTTO) or specific hydraulic fluid, e.g., ISO VG 32/46
Coolant Specification:
Ethylene glycol based antifreeze/coolant mixture, e.g., 50/50 with distilled water
Common Wear Points:
Hydraulic pump wear, PTO clutch wear, front axle kingpin wear, minor electrical issues
Engine Reliability:
BMC engines are generally robust but require diligent maintenance; common issues include injector pump calibration and starter motor reliability
Transmission Notes:
Synchromesh wear in higher gears can be an issue, potential for bearing noise
Manufacturer Origin:
Nuffield, British tractor manufacturer, part of the BMC (British Motor Corporation) group
Historical Context:
Nuffield was a significant player in British agricultural machinery from the mid-20th century
Production Era:
BMC Mini Tractors were produced roughly from the 1950s into the 1970s, often with variations and rebadging
Key Models:
Nuffield Universal models, Leyland 154, Marshall 154 (often shared BMC components)
