Cooling System Type:
Water-cooled, typically with a radiator, fan, and thermostat.
Lubrication System Type:
Pressurized lubrication system with oil pump, oil filter, and oil sump.
Engine Bore Stroke:
Specifics vary by engine variant, but typical for David Brown engines of this era, e.g., for a 3.1L engine, bore might be ~91.5mm and stroke ~120mm.
Ignition System Type:
Compression ignition (Diesel)
Transmission Type:
Manual gearbox with multiple forward and reverse gears. Common configurations included a 12-speed 'David Brown Selectamatic' or similar mechanical transmission.
Optional Features:
Differential lock, possibly independent PTO options depending on model year and specification.
Transmission Features:
Constant mesh gears, robust construction designed for heavy agricultural use.
Gear Ratios:
Detailed gear ratios for all forward and reverse gears are provided in the manual for proper troubleshooting and repair.
Wheelbase:
Varies by specific configuration, but typical for tractors of this era would be in the range of 70-80 inches.
Operating Weight:
Typically around 4,000 - 5,000 lbs (unballasted), depending on configuration.
Rear Tire Size:
Commonly 13.6/12-28 or 14.9/13-28 agricultural tires.
Front Tire Size:
Commonly 6.00/16 or 7.50/16 agricultural tires.
Engine Oil Change Interval:
Typically every 100-250 operating hours, depending on operating conditions and oil type specified in the manual.
Fuel Filter Replacement Interval:
As per manual recommendations, often tied to operating hours or fuel quality, typically every 250-500 hours.
Air Filter Maintenance:
Regular cleaning/replacement based on operating environment, critical for engine longevity.
Engine Oil Specification:
API CD or CE rated diesel engine oil, viscosity grade typically SAE 15W-30 or 10W-30 depending on ambient temperature (refer to manual for precise recommendation).
Hydraulic Fluid Specification:
Tractor Hydraulic Fluid (THF) or equivalent, often meeting specific David Brown or industry standards. Capacity around 25-30 liters.
Transmission Oil Specification:
Gear oil, typically SAE 90 EP (Extreme Pressure) or a universal tractor transmission fluid (UTTO) if specified for combined hydraulic/transmission lubrication.
Common Issues:
Wear in the Selectamatic hydraulic control system, potential for clutch wear, minor electrical system issues common in older tractors, leaks from seals and gaskets.
Engine Oil Capacity:
Approximately 5-7 liters (refer to manual for precise capacity and dipstick checking procedure).
Transmission Hydraulic System Capacity:
Approximately 25-30 liters (for combined transmission and hydraulic oil).
Oil Filter Part Number:
Refer to manual for specific part numbers, but common aftermarket equivalents exist (e.g., Fram PH16, Wix 51085 - always verify with manual/tractor parts).
