Engine Family:
Likely Case IH/International Harvester 3-cylinder diesel engine (e.g., from the D-series)
Engine Displacement:
Commonly around 2.3 to 2.7 liters (140-165 cubic inches) for 3-cylinder models of this era.
Bore X Stroke:
Specifics vary by exact engine variant, but typical for this size would be around 91-96mm bore and 102-108mm stroke.
Compression Ratio:
Typically in the range of 17:1 to 19:1 for naturally aspirated diesel engines of this period.
Horsepower Rating:
Likely in the range of 40-55 PTO horsepower.
Torque Rating:
Estimated peak torque around 100-130 lb-ft, depending on specific engine tune.
Injection System:
Direct injection, likely rotary or inline injection pump (e.g., Simms, CAV, Bosch).
Oil Type Recommendation:
API CD or CE rated diesel engine oil, SAE 15W-40 or 10W-30 depending on climate (as per manual)
Oil Filter Part Number Example:
May correspond to common Case IH filters like 3222107A1 or equivalents.
Transmission Type:
Gear drive transmission
Number Of Speeds:
Typically 8 forward and 2 reverse speeds (e.g., 8x2 synchronized or unsynchronized gearbox).
Power Take Off Pto:
Standard 540 RPM PTO, potentially 540/1000 RPM option depending on configuration.
Clutch Type:
Dry dual-stage clutch (for transmission and PTO engagement)
Differential Lock:
Foot-pedal operated differential lock on rear axle
Transmission Fluid Type:
Commonly SAE 80W-90 GL-4 gear oil or dedicated tractor hydraulic fluid (THF) depending on shared sump design. Manual specification is critical.
Wheelbase:
Approximate wheelbase: 79-83 inches (200-211 cm).
Overall Length:
Approximate overall length: 120-130 inches (305-330 cm).
Overall Width:
Approximate overall width (rear track): 50-65 inches (127-165 cm), adjustable.
Shipping Weight:
Approximate shipping weight: 4500-5000 lbs (2040-2270 kg).
Operating Weight:
Operating weight with typical fluids and operator: 5000-5500 lbs (2270-2500 kg).
Engine Oil And Filter Change:
Typically every 250-500 operating hours or annually. Manual will specify exact interval.
Transmission And Hydraulic Fluid Change:
Intervals vary, but often 1000-1200 operating hours. Crucial to follow manual for shared sumps.
Air Filter Maintenance:
Inspect and clean/replace as needed, typically every 250 hours or when restriction indicator shows.
Fuel Filter Replacement:
Typically every 500 operating hours or annually, or as per manual recommendation.
Engine Oil Viscosity:
SAE 15W-40 (standard temperature), SAE 10W-30 (cold weather) as recommended.
Hydraulic Fluid Type:
Case IH TCH Fluid (or equivalent Universal Tractor Transmission Fluid - UTTO / THF specification).
Coolant Type:
Ethylene glycol based coolant, 50/50 mix with distilled water. Manual will specify concentration and type.
Common Issue 1:
Hydraulic system performance degradation (e.g., slow lift arms) due to worn pump or contaminated fluid.
Common Issue 2:
Wear in the transmission synchronizers or gears, leading to difficult shifting.
Common Issue 3:
Electrical system issues, particularly related to aging wiring harnesses and connections.
Common Issue 4:
Wear on PTO clutch or engagement mechanisms.
Parent Company:
Case Corporation (later Case IH, part of CNH Industrial)
Heritage Context:
Case IH has a long history of agricultural machinery manufacturing, dating back to the 19th century.
Predecessor Models:
Likely evolved from earlier International Harvester 300, 330, or similar utility tractors.
Era Of Production:
The 385 was part of the Case IH 300/400 series, typically produced in the 1980s.
Manufacturing Location:
Primarily manufactured in Europe (e.g., Doncaster, UK or Neuss, Germany) for the European and global markets.
