Diagnostic Focus: Primarily focused on electrical system diagnosis and repair. 📊 Manual Specifications File Format Digital Format: Likely PDF, potentially with layers for clarity or searchability. Print Quality Print Readability: Designed for clarity, with crisp lines and legible text for professional use. Binding Type Physical Binding: If printed, typically spiral-bound or perfect-bound for ease of use in a workshop. Paper Type Physical Paper: If printed, often on durable, matte-finish paper to reduce glare and withstand workshop conditions. ⚙️ Engine Specifications Primary Engine Engine Families Common: D12, D13, D16 (common for FM/FH series around this period; specific engines depend on chassis configuration) Performance Power Output Range: Varies significantly by engine. Typically from 300 HP to over 700 HP. Torque Output Range: Varies significantly by engine. Typically from 1000 lb-ft to over 2000 lb-ft. Fuel System Injection Type: Common Rail Direct Injection (CRDI) is standard for these engines. Emissions Control: Depending on market and specific configuration, may include EGR (Exhaust Gas Recirculation), SCR (Selective Catalytic Reduction) for Euro 4/5 compliance. 🔧 Transmission Standard Gearbox Types Common: Volvo I-Shift (automated manual transmission), Fuller Roadranger (manual), ZF manual transmissions. Optional Automatic Options: Various Allison automatics for specific vocational applications may also be present. Features Transmission Control Electrical: I-Shift and other automated transmissions have complex electrical control modules and wiring. 📐 Dimensions Exterior Cab Configurations: Day Cab, Sleeper Cab (various lengths and heights). Axle Configurations: 4x2, 6x2, 6x4, 8x4, etc. Weights Gvw Range: Gross Vehicle Weight (GVW) typically ranges from 18,000 kg (40,000 lbs) to over 32,000 kg (70,000 lbs) for tractor units, and higher for specialized configurations. Gvwr Range: Gross Combination Weight Rating (GCWR) can exceed 60,000 kg (132,000 lbs). 🛡️ Safety Features Ratings Crash Testing Focus: Focus on occupant safety in cab, though specific rating systems (like NCAP for cars) are less directly applicable to heavy trucks in the same way.
