Type:
BMC (British Motor Corporation) engines, available in Diesel and Petrol variants.
Diesel Variants:
Likely based on BMC's smaller diesel engine offerings of the era, often a 3-cylinder configuration.
Petrol Variants:
Likely based on BMC's smaller petrol engine offerings, possibly a 4-cylinder configuration.
Horsepower Range:
Estimated 20-40 HP (specific figures vary by engine variant and model year).
Torque Characteristics:
Designed for low-end torque suitable for agricultural work.
Diesel Injection:
Likely mechanical direct or indirect injection systems. Specific pump brands (e.g., CAV, Simms) would be detailed in the manual.
Petrol Carburetion:
Single or multi-point carburetors. Specific carburetor models (e.g., Zenith, Solex) would be detailed.
Engine Oil Change:
Typically every 50-100 operating hours, specific recommendations in the manual.
Greasing Points:
Daily or weekly greasing of key pivot points and bearings as per the manual's lubrication chart.
Air Filter Service:
Regular cleaning or replacement of the air filter element, especially in dusty conditions.
Engine Oil:
Recommended oil viscosity (e.g., SAE 30, 15W-40) and API service classification for both Diesel and Petrol engines. Capacity would be detailed.
Hydraulic Fluid:
Specific hydraulic fluid type and grade (e.g., UTF - Universal Tractor Fluid, or specific hydraulic oil) and capacity. Likely ISO VG 32 or 46.
