Engine Type:
Likely British Leyland four-cylinder diesel engines (specific models vary, but typically derived from Perkins or Leyland designs). The model numbers (344, 384) suggest displacements around 3.44 and 3.84 liters respectively, common for these tractor classes.
Typical Horsepower Range:
Leyland 255 (approx. 50-55 HP), Leyland 270 (approx. 60-65 HP). Exact figures vary based on specific engine variants and tune.
Torque Output:
Torque figures would be optimized for low-RPM pulling power, typically in the range of 130-170 lb-ft (175-230 Nm) at around 1300-1600 RPM. Exact specifications in manual.
Injection System:
Likely a mechanical injection pump system (e.g., CAV or Simms) with direct or indirect injection depending on the specific engine variant.
Cooling Method:
Water-cooled, typically with a radiator, fan, and thermostat.
Engine Design:
Likely a robust, naturally aspirated diesel engine designed for reliability and torque delivery in agricultural environments.
Engine Oil Change:
Typically every 250-500 operating hours or annually. Specific intervals detailed in the manual.
Transmission Oil Change:
Refer to manual, typically every 500-1000 operating hours, depending on duty cycle.
Engine Oil Type:
Refer to manual for specific API/ACEA classifications. Common for the era would be SAE 30 or 15W-40 diesel engine oil.
Hydraulic Fluid Type:
Hydraulic Transmission Fluid (HTF) or Universal Tractor Transmission Oil (UTTO) conforming to specific viscosity and additive requirements detailed in the manual.
Coolant Type:
Ethylene glycol-based antifreeze/coolant mixture, typically a 50/50 mix with distilled water, for freeze and corrosion protection. Manual will specify concentration and type.
Common Wear Points:
Steering components (kingpins, bushes), clutch wear, hydraulic pump seals, and PTO shaft wear are common on older tractors. The manual provides procedures for inspection and repair.
