Binding Type Binding: N/A (Digital Format) Paper Type Paper Specification: N/A (Digital Format) ⚙️ Engine Specifications Primary Engine Engine Model: DaimlerChrysler (Mercedes-Benz) MBE4000 Performance Emission Standard: EPA07 (Environmental Protection Agency 2007 emissions standards) Fuel System Fuel Delivery: Likely Common Rail Direct Injection (CRDI) for EPA07 compliant engines. Displacement Engine Displacement: 12.0 Liters (Common for MBE4000) Horsepower Range Hp Options: Varies by application, typically 350-450 HP. Torque Range Torque Options: Varies by application, typically 1200-1550 lb-ft. Engine Features Cylinder Configuration: Inline 6-Cylinder Emission Controls Aftertreatment System: Likely Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF) to meet EPA07. 🔧 Transmission Standard Transmission Type: Manual transmissions (e.g., Eaton Fuller) and automatic transmissions (e.g., Allison) were common in these Freightliner models. Optional Transmission Options: Various manufacturer options available depending on the specific truck model and vocational use. Features Transmission Function: This service bulletin's primary focus is the engine, not the transmission, but correct engine operation is crucial for transmission performance. 📐 Dimensions Exterior Cab Configurations: COE (Cab Over Engine) and Conventional cab configurations are listed, indicating significant variation in wheelbase and overall length. Weights Gvwr Range: Gross Vehicle Weight Rating varies significantly across the listed models, from Class 7 heavy-duty trucks to Class 8 vocational and line-haul trucks. 🛡️ Safety Features Ratings Crash Test Information: Specific crash test data would be model and year-dependent; TSBs typically do not cover this. Active Features Operational Safety: Properly functioning fuel and air lines are critical for reliable engine operation, indirectly impacting vehicle safety. Passive Features Structural Safety: Vehicle chassis and cab design are primary passive safety features, not directly addressed by this engine-focused TSB. 💡 Technology Features Infotainment Vehicle Infotainment: Infotainment systems were rudimentary in many of these trucks from the EPA07 era compared to modern vehicles, focusing on practical driver information and basic audio. Driver Assistance Adas Features: Advanced Driver Assistance Systems (ADAS) were not prevalent in this era of commercial trucks. Focus was on ABS and engine diagnostics. Connectivity Telematics: Basic telematics for fleet management might have been available on higher-spec models. 🔧 Maintenance Service Intervals Engine Maintenance General: Regular oil changes, filter replacements, and inspections are standard for MBE4000. Specific intervals (e.g., oil change every 25,000-50,000 miles or annually) depend on application and oil type. This TSB addresses a specific component replacement, not routine maintenance intervals. Fluid Specifications Engine Oil Type: API CJ-4 or CK-4 rated synthetic or semi-synthetic diesel engine oil, viscosity typically 15W-40 or 10W-30 depending on climate. Refer to the primary service manual for exact specifications. Known Issues Mb Engine Common Concerns: Issues with EGR coolers, DPF regeneration, and certain fuel system components can occur on EPA07 engines. This TSB specifically targets a potential problem with H01 and H02 lines, implying a recall or a design update for reliability or performance related to those specific lines. Filter Part Numbers Oil Filter Example: Example: Fleetguard LF9009, Baldwin B206. Specific filters depend on engine serial number and application. This TSB does not provide general filter part numbers. Component Identification H01 H02 Lines Purpose: The exact function of H01 and H02 lines is not explicitly stated without the TSB content, but they are likely related to the fuel system, air intake, or emissions control systems of the MBE4000 engine. 📚 Vehicle History Brand Heritage Freightliner Legacy: Freightliner Trucks, a division of Daimler Truck...
