Engine Type:
Likely a diesel engine, common for David Brown tractors of this era.
Engine Family:
David Brown 3-cylinder or 4-cylinder diesel engine. Specific displacement not provided but typical for the era would be in the 3.0-4.5 liter range.
Horsepower Range:
Estimated 50-70 HP, typical for a tractor of this classification in the 1980s.
Injection System:
Likely a mechanical rotary or inline injection pump system. Specific brand (e.g., CAV, Lucas) not detailed.
Transmission Type:
Likely a constant mesh, unsynchronized or partially synchronized manual gearbox. David Brown offered various configurations, including 8-speed or 12-speed options (e.g., with a Hi-Lo splitter).
Transmission Options:
Possible variations in gear ratios or additional speed ranges. PTO (Power Take-Off) speeds would also be a factor.
Clutch:
Dual-stage clutch likely standard for independent PTO operation.
Infotainment System:
N/A (Tractor from the era would have basic instrumentation, no infotainment system.)
Driver Assistance Features:
N/A (Tractor from the era would have basic controls, no electronic driver assistance.)
Connectivity Features:
N/A (No electronic connectivity features present.)
Engine Oil Change:
Typically every 250-500 operating hours, dependent on operating conditions.
Transmission Oil Change:
Approximately every 1000-1200 operating hours.
Engine Oil Grade:
Likely API CD or CE rated, SAE 15W-40 or 10W-30 (depending on climate).
Hydraulic Fluid Type:
Hydraulic Transmission Oil (HTO) or Universal Tractor Transmission Oil (UTTO), meeting specific David Brown specifications (e.g., DB 261).
Coolant Type:
Ethylene glycol-based antifreeze/coolant with corrosion inhibitors, typically a 50/50 mix with distilled water.
Common Wear Points:
Wear in the transmission synchronizers (if applicable), clutch wear, potential hydraulic pump or cylinder leaks, starter motor issues, and wear on PTO components.
Electrical Problems:
Corrosion on electrical connections, alternator/generator issues, wiring harness degradation over time.
