Typical Torque:
Dependent on specific engine variant, but designed for agricultural torque requirements.
Injection Type:
Typically direct injection, possibly with rotary or inline fuel pumps (e.g., Simms, CAV).
Cooling Method:
Water-cooled, typically via a pump and radiator with fan assistance.
Oil Type Recommendation:
Refer to specific manual chapters for appropriate API service classification and viscosity grades (e.g., SAE 30, 10W-30 depending on climate).
Common Engine Series:
BMC E-Series diesel engines (e.g., EH for 3-cylinder, EJ for 4-cylinder).
Gearbox Type:
Manual transmission with multiple forward and reverse gears.
Transmission Options:
Some models may have offered PTO (Power Take-Off) gears, differential lock, or auxiliary PTO units.
