Make Model:
Likely a David Brown diesel engine, specific model not explicitly stated but characteristic of the 1490 tractor.
Cylinder Count:
Typically 4-cylinder diesel for this class of tractor, but confirmation via manual required.
Displacement:
Around 3.5 to 4.0 liters, characteristic of David Brown tractors from this era (e.g., similar to the 885/995/1210 series engines).
Horsepower Range:
Estimated around 70-80 PTO horsepower, but requires manual confirmation.
Injection Type:
Direct injection or indirect injection, depending on the specific engine variant. Manual will specify.
Fuel Delivery:
Typically rotary or inline injection pump. Specifics in manual.
Type:
Manual transmission, likely with a multi-speed gearbox (e.g., 8-speed or 12-speed forward and 4-speed reverse). Specifics in manual.
Features:
Possible availability of a high-low (reduction) gear for increased torque or speed variations. Confirmation via manual.
Clutch Type:
Dual-stage clutch for transmission and PTO engagement, common on David Brown tractors of this era.
Transmission Oil:
Requires specific tractor transmission fluid (e.g., API GL-4 or equivalent, viscosity grade typically SAE 80W/90 or SAE 10W-30 depending on climate and application). Manual to confirm exact specification and capacity.
Wheelbase:
Typical for tractors of this era, likely around 2200-2300 mm. Specific measurement in manual.
Overall Length:
Estimated around 3800-4000 mm. Specific measurement in manual.
Overall Width:
Likely adjustable track widths, with a typical operating width of 1800-2000 mm. Specifics in manual.
Operating Weight:
Typically around 2500-3000 kg without ballast. Manual will provide exact specifications.
Engine Oil Change:
Typically every 250 hours of operation or annually, whichever comes first. Manual will specify the exact interval and oil type.
Air Filter Service:
Check and clean or replace as needed, typically every 100-250 hours depending on operating conditions. Manual provides detailed guidance.
Fuel Filter Replacement:
Recommended replacement at regular intervals, e.g., every 500 hours or annually. Manual will specify.
Transmission Oil Change:
Typically every 1000-1200 hours or every two years. Manual will detail the interval and fluid capacity.
Engine Oil:
Multi-grade diesel engine oil, typically API CD or CE or higher. Viscosity grade commonly SAE 15W-40 or SAE 10W-30 for colder climates. Manual to confirm exact API rating and viscosity.
Coolant:
Ethylene glycol-based antifreeze mixture, typically 50/50 with distilled water for freeze protection and corrosion inhibition. Manual specifies type and capacity.
Common Wear Points:
Typical wear points might include clutch wear, hydraulic pump efficiency, PTO engagement, and certain electrical connections. Manual provides diagnostic procedures for these.
Potential Failures:
As with any older tractor, potential issues could involve seal leaks, injector pump calibration, and minor electrical gremlins. The manual is crucial for addressing these.
