This official publication provides a structured reference for mechanical components across the entire 6-26t chassis range. The material organizes technical data into thirteen primary sections. Mechanics will find complete overviews covering general vehicle specifications, engine overhaul, clutch, gearbox, and axle assemblies. It also details the pneumatic braking systems and routine service requirements. Technical topics transition logically from basic chassis identification and lubrication standards to intensive engine assembly. This includes cylinder head removal, injector replacement, and timing gear configuration for the direct-injection common rail engines (F4AE0481D/C/A and F4AE0681E/D/B/A power variants). Exploded-view diagrams and descriptive text guide the reader, ensuring accurate component identification and fitting positions during shop work.

The technical data sections deliver comprehensive torque values for critical fasteners. You will find specifications ranging from engine cylinder head bolts to gearbox housing screws. Fluid capacities for engine oil, coolant, and hydraulic systems are clearly listed alongside specific lubricant designations to ensure standard operating fluids are utilized. The F4AE engine data section documents essential metrics: compression ratios, bore/stroke dimensions, and valve clearance settings required for exact timing accuracy. Intake valve clearance, for instance, is listed at 0.25 mm. The manual also outlines connector pinout tables and diagnostic reference thresholds for the common rail system to aid in electronic fault analysis. Assembly precision is supported by exact torque values, such as 80 Nm for the main bearing caps and 50 Nm for the fuel manifold. The cooling system thermostat is specified to open at 82.2°C, while exact coolant capacities vary based on the chassis configuration. Prior to beginning any heavy repairs or component assembly, ensure you always observe standard workshop safety protocols. Reviewing the complete technical specifications in this reference material is critical for maintaining original factory clearances and ensuring long-term vehicle reliability.
