Transmission Component Identification: Gears, shafts, synchronizers, bearings, seals, shift forks, clutch components. Hydraulic Component Identification: Hydraulic pump, control valve, cylinders (lift, steering), hoses, fittings, reservoir. Brake System Identification: Brake discs, pads, calipers, master cylinder, brake lines, parking brake mechanism. Technical Depth Technical Depth: Component identification and sourcing, detailed illustrations for part location, essential for DIY mechanics and basic maintenance/repair planning Part Number Specificity: Extremely high. The primary purpose is to list exact part numbers for ordering replacement components. Illustration Detail: Detailed exploded views showing the order of assembly and interaction of parts, crucial for correct reassembly. Diagnostic Support: While not a diagnostic manual, identifying correct parts is the first step in any repair and aids in troubleshooting. 📊 Manual Specifications File Format File Format: Portable Document Format (PDF) Searchability: PDF format typically allows for text searching if the OCR layer is good, but primarily relies on visual navigation via table of contents and diagrams. Print Quality Print Quality: Suitable for printing specific pages or the entire manual, implies good resolution for detailed illustrations Printable Pages Benefit: Enables users to print only necessary sections for field repairs or workshop use, saving resources and providing quick access to relevant information. Binding Type Binding Type: Digital Download (PDF) - implies user will print and bind as desired Paper Type Paper Type: User-defined upon printing ⚙️ Engine Specifications Primary Engine Primary Engine: Typically powered by a Belarus D-260 series diesel engine (specific variant may depend on sub-model and year, often 6-cylinder) Engine Model Example: D-260.2 (a common variant for this horsepower range) Performance Estimated Horsepower: Around 120-130 HP (for the 1221 series) Estimated Torque: Refer to specific D-260 engine variant specifications, generally high torque for pulling power. Fuel System Fuel System: Mechanical fuel injection, often with a rotary or inline injection pump. Filter systems are robust. 🔧 Transmission Standard Transmission Type: Synchronized mechanical gearbox Optional Optional Features: Some variants may offer a creeper gear or power shift options, though the base is typically manual. Features Gear Configuration: Multi-speed, typically with a range of forward and reverse gears (e.g., 16 forward, 8 reverse) allowing for a wide spectrum of operating speeds. 📐 Dimensions Exterior Overall Length: Approximately 4.9-5.2 meters (varies slightly by configuration) Overall Width: Approximately 2.2-2.5 meters (varies with tire configuration) Height To Cab: Approximately 2.8-3.0 meters Wheelbase: Approximately 2.7 meters Weights Operating Weight: Around 5.5-6.5 tonnes (without ballast) Front Axle Load: Designed for significant front axle load, often requiring front ballast for stability. Rear Axle Load: High rear axle load capacity to handle traction demands. 🛡️ Safety Features Ratings Safety Ratings: No specific official crash test ratings like passenger cars; safety features focus on operational safety for heavy machinery. Active Features Active Safety Features: Effective braking system (often wet disc brakes on rear), differential lock for improved traction, ROPS (Roll Over Protective Structure) if fitted with a cab.
