Model:
Based on David Brown's established diesel engine range for this era. Likely a variant of the 'AD' series engines.
Configuration:
Likely a 4-cylinder diesel engine.
Displacement:
Commonly around 3.5 to 4.0 liters (approx. 210-245 cu in) for this class of tractor.
Horsepower:
Estimated range of 50-70 PTO horsepower, depending on specific engine tune and configuration.
Torque:
Details would be found in the manual, critical for PTO operations and heavy draft work.
Injection Type:
Direct injection diesel, likely utilizing a Lucas CAV or similar inline fuel injection pump.
Type:
Water-cooled, pressurized system with a radiator and fan.
Oil Type:
API CE or CD classification heavy-duty diesel engine oil, typically SAE 15W-40 or 10W-30 depending on ambient temperature. Specifics in manual.
Type:
David Brown's own transmission design, likely a constant mesh gearbox with multiple forward and reverse speeds, possibly including a synchronized shuttle or creeper gear option.
Speeds:
Typically 12 or 16 forward speeds and 4 or 6 reverse speeds. The manual would detail specific gear ratios.
Features:
Optional 'Hydro-Shift' or powershift capabilities might have been available on some variants, though less common for this model. PTO options standard.
Pto:
Standard 540/1000 RPM PTO, with detailed servicing and clutch adjustment procedures covered.
Oil Type:
API GL-4 or GL-5 rated tractor hydraulic fluid or 80W/85W gear oil for the gearbox. Specific John Deere JDM J20C or equivalent may be specified for wet brake systems if applicable. Manual is crucial for this.
Length:
Varies by configuration, generally around 3.5-4.0 meters.
Width:
Varies by tread settings, typically 1.8-2.2 meters.
Height:
To top of steering wheel/dashboard typically around 1.5-1.8 meters.
Operating Weight:
Typically in the range of 2500-3500 kg (unballasted).
Max Towing Capacity:
Detailed in manual, dependent on chassis and drawbar specification.
Rollover Protection:
ROPS (Roll-Over Protective Structure) may have been an option or standard on later models. Manual will cover installation and maintenance if applicable.
Brakes:
Hydraulically operated disc brakes, typically located inboard on the rear axle. Manual details adjustment and overhaul.
Seatbelt:
Seatbelt availability and installation procedures if equipped with ROPS.
Engine Oil Change:
Typically every 250-500 operating hours, or annually. Manual provides precise intervals based on duty cycle.
Air Filter Replacement:
As needed, depending on operating conditions, but typically checked at every oil change and replaced if dirty.
Fuel Filter Replacement:
Every 500 operating hours or annually, or as required if fuel system issues arise.
Transmission Oil Change:
Typically every 1000-1500 operating hours. Manual will specify.
Hydraulic Fluid:
MS-1316 (Caterpillar TO-4), Ford M2C134D, or equivalent universal tractor transmission oil (UTTO). Check manual for precise specification and compatibility, especially with wet brakes.
Coolant:
50/50 mixture of ethylene glycol coolant and distilled water, with appropriate corrosion inhibitors for heavy-duty diesel engines.
Common Problems:
Potential issues include wear in the gearbox synchronizers, hydraulic pump wear, and starter motor issues. Seal and gasket deterioration over time. Manual addresses diagnosis and repair.
