Engine Oil Change:
Typically every 250 hours or 12 months, depending on operating conditions.
Fuel Filter Replacement:
Recommended at 500 hours or annually, or when experiencing fuel delivery issues.
Hydraulic Fluid Change:
Typically every 1000 hours or 24 months.
Engine Oil:
API CE/CF or equivalent diesel engine oil, SAE 15W-40 or 10W-30 depending on temperature range (refer to manual for precise recommendation).
Hydraulic Fluid:
Typically an UTF (Universal Tractor Transmission Fluid) or ISO VG 46 hydraulic oil. Specific Case IH specifications may apply (e.g., HYTRAN).
Transmission Fluid:
Often shared with hydraulic fluid (UTF/HYTRAN) in models with a common sump for transmission, hydraulics, and differential.
Coolant Type:
Ethylene glycol based antifreeze/coolant with corrosion inhibitors, typically a 50/50 mix with distilled water.
Grease Type:
Lithium-based multipurpose grease for lubrication points and bearings.
Common Wear Items:
Clutch wear, hydraulic pump performance degradation over time, front axle wear, starter motor reliability.
Electrical Problems:
Wiring harness degradation, particularly around the engine bay and operator station due to vibration and environmental exposure.
Cooling System:
Radiator leaks, thermostat issues, and fan belt slippage can lead to overheating.
Heritage:
David Brown was a British tractor manufacturer, acquired by Tenneco in 1988, which later integrated it into Case IH. These tractors represent a significant period in David Brown's history before full integration.
Production Period:
The 385, 485, 585, 685, and 885 series were predominantly produced in the 1980s.
Design Philosophy:
Robust, reliable, and practical design focused on farm work, embodying the strengths of both David Brown and early Case IH engineering.
Manufacturing Location:
Primarily manufactured at the David Brown/Case IH facilities in Meltham, West Yorkshire, UK.
