Bore And Stroke:
Specific dimensions would be detailed in the manual, but typically inline diesel configurations for BMC engines.
Performance
Displacement Range:
Likely in the 3.4 to 3.8 litre range for models listed (e.g., 3DL suggests 3.4L, 460 often associated with 3.8L)
Torque Characteristics:
Designed for high torque output at low RPMs, typical of diesel engines for agricultural applications.
Fuel System
Fuel Type:
Diesel
Injection Type:
Direct injection (typical for BMC diesel engines of the era)
Fuel Pump Type:
Inline injection pump (e.g., CAV or Simms, depending on the specific engine variant).
🔧 Transmission
Standard
Type:
Manual gearbox (likely constant mesh or crash gear type, common for the era)
Features
Gear Options:
Multiple forward gears (e.g., 4, 6, or 8 speeds) and reverse, with some models offering a creeper gear option.
Clutch Type:
Single dry plate clutch, operated by a foot pedal.
Differential Lock:
Many Nuffield models featured a differential lock operated by a foot pedal for enhanced traction.
Optional
Power Take Off Pto Speeds:
Standard PTO speeds, likely 540 RPM or 540/1000 RPM depending on the specific model variant.
