Torsional Vibration Damper The torsional vibration damper with decoupled belt pulley suppresses longitudinal vibration and reduces noise. It is mounted at front of the crankshaft with 4 bolts torque loaded to 45 Nm.
ENGINE - V DESCRIPTION AND OPERATION Bearing Shells The upper bearing shells have oil grooves and a drilling to provide oil, via drillings in the crankshaft to the crankshaft main bearings and the connecting rod journals Flywheel 1 Flywheel 2 Torque converter attachment holes 3 Reluctor ring 4 Starter motor ring gear The single piece steel flywheel is bolted to the rear of the crankshaft with nine bolts. The torque converter is bolted to the rear of the flywheel with four bolts. Attached to the flywheel is the reluctor ring for the crankshaft position sensor and the starter motor ring gear.
ENGINE - V8 DESCRIPTION AND OPERATION 12-2-7 Connecting Rods The connecting rods are sintered type, one piece forged rods which feature a fracture-split at the big-end between the connecting rod and the bearing cap. The mating surface of the rod and bearing cap form a rough surface (interference fit) that eliminates the need for centering sleeves. Each matched rod and bearing cap pair is stamped with a pairing code. All of the rods are of one weight class and conform to the double bearing classification, red or blue. One red and one blue bearing shell are fitted to each connecting rod. The red shell is fitted to the bearing cap. Pistons The pistons are of a short skirt design andiron coated for use with the Alusil block. Each piston has a flat crown surface with a front facing arrow for installation direction. The relevant cylinder bank number is engraved into the piston crown. Each piston is fitted with two compression rings and an oil control ring. There are no thermal control strips in the pistons. The pistons are cooled with specific spray jets, mounted in the crankcase. M12 7806
