Searchability: Depends on OCR quality; ideally searchable by part number or description. Print Quality Diagram Clarity: High resolution diagrams are crucial for EPCs; quality of original scans or source data is key. Binding Type Digital Binding: N/A (Digital Format) Paper Type Digital Paper Type: N/A (Digital Format) ⚙️ Engine Specifications Primary Engine Engine Families: Zetor's own diesel engines, likely based on the Zetor UR I engine family evolution, with displacements varying by model number (e.g., 33xx series likely smaller displacement, 73xx series larger). Engine Type: Typically 3-cylinder or 4-cylinder, naturally aspirated or turbocharged diesel engines. Bore Stroke: Highly variable based on specific engine variant. For example, earlier Zetor engines could have bore/stroke combinations around 95mm x 110mm, but this needs model-specific verification. Performance Horsepower Range: Estimated range from approximately 35 HP (33xx series) to 70 HP (73xx series). Torque Range: Estimated range from approximately 100 Nm to 250 Nm, dependent on engine size and configuration. Fuel System Fuel Injection: Mechanical direct injection, often with distributor-type or inline fuel injection pumps (e.g., Zetor Z 2011 series). Fuel Type: Diesel Fuel. Fluid Specifications Engine Oil Type: Typically SAE 15W-40 API CG-4 or higher, but always consult specific service manuals for exact specifications and capacities (e.g., 7-10 liters). Coolant Type: Ethylene glycol-based antifreeze (50% concentration recommended) for protection down to -37°C. 🔧 Transmission Standard Type: Manual gearbox with synchronized gears, typically 8 or 12 forward speeds and 4 reverse speeds (e.g., Zetor 5401.000 gearbox). Optional Powershift: Some higher horsepower models might have offered a powershift option (e.g., 'Synchronized with Hydraulic Shuttle'). Features Pto: Standard 540 RPM PTO, with optional 1000 RPM or ground-speed PTO on some models. Often mechanically driven. 4Wd: Models ending in '41' (e.g., 3341) are 4WD (four-wheel drive) versions, equipped with a front drive axle. Fluid Specifications Transmission Oil Type: Typically GL-4 or GL-5 rated gear oil, viscosity SAE 80W-90 or 85W-140 depending on ambient temperature. Capacity varies greatly. 📐 Dimensions Exterior Wheelbase: Varies by model, approximately 1800mm to 2150mm for 2WD and slightly more for 4WD. Length: Approximately 3500mm to 4000mm. Width: Approximately 1700mm to 2000mm (at rear track). Weights Operating Weight: Varies significantly, from around 1800 kg to 2800 kg, depending on...
