Mechanical Systems and Component Documentation

This factory reference details the technical architecture and maintenance requirements for the F116 engine and chassis systems. It breaks down complete engine overhauls, covering everything from cylinder liner and piston replacement to crankshaft assembly and cylinder head service. Technicians will find the precise valve timing configurations and belt tension settings required for maintaining this specific V12 powerplant. Additionally, the manual explores the oil and cooling systems by providing functional descriptions, component layouts, and critical fluid capacity data necessary for accurate shop-floor diagnostics.

Specification Highlights

Engine identification and build parameters are clearly outlined for the entire F116 series. The text provides essential data for crankshaft journal clearances, piston-to-liner fits, and camshaft alignment markings. Torque specifications are thoroughly documented for major fasteners, including the critical 125 Nm final-stage requirement for cylinder head studs.

Working on high-performance powertrains requires strict adherence to factory procedures. Always verify specific torque values and safety margins prior to final assembly to ensure reliable operation and prevent mechanical failure.

For quick reference, the cooling system capacity is listed at 14 liters. The crankshaft specification table sets the main journal installation clearance between 0.013 and 0.018 mm, while intake valve clearance is specified at 0.20–0.25 mm.
