Vibration Damper - BMW N55 Manual

Vibration Damper

A single-mass vibration damper is used on the N55 engine. The belt pulley is mounted
on the secondary pulley. Compared to the N54 engine, this design layout additionally
reduces the belt load as the vulcanization decouples the belt pulley with flywheel mass
from the crankshaft.
