Engine Manufacturer:
Likely BMC (British Motor Corporation) or Leyland, typically 3 or 4 cylinder diesel engines.
Displacement:
Commonly around 2.6 to 3.8 liters (160 to 230 cubic inches), depending on the specific variant.
Horsepower Range:
Approx. 40-50 HP (gross) at rated engine speed.
Injection System:
Direct injection with rotary or inline injection pumps (e.g., CAV).
Engine Oil Change:
Typically every 150-250 operating hours or annually.
Air Filter Service:
Regular checks and cleaning/replacement based on operating conditions (e.g., dusty environments).
Engine Oil:
API CD or CE rated diesel engine oil, typically SAE 15W-40 or 10W-30 depending on climate. Capacity approx. 5-7 liters.
Transmission Hydraulic Fluid:
Universal Tractor Transmission Oil (UTTO) or a suitable hydraulic fluid meeting specifications like Ford M2C134-D. Capacity approx. 18-25 liters.
Coolant:
Ethylene glycol-based antifreeze mixture, typically 50/50 with distilled water. Capacity approx. 10-12 liters.
Common Wear Points:
Hydraulic pump and cylinder seals, clutch wear, and potential wear in the PTO gearbox.
Electrical Reliability:
Older wiring harnesses can degrade, leading to intermittent electrical issues.
Engine Starting:
Cold weather starting can be challenging without proper glow plug operation and fuel system maintenance.
Manufacturer Origin:
Nuffield was a British tractor brand, part of the British Leyland group, known for robust and reliable agricultural machinery.
Development:
The 460 was a mid-range utility tractor, building on Nuffield's experience with earlier models like the DM4 and 3DL, and was part of a line that included models like the 3/42, 4/60, and 4/65.
Production Period:
Produced from the late 1960s through the early 1970s.
