Final Drive Sprocket - Volkswagen 2004 Jetta Introduction Manual

Final Drive Sprocket

High torsional irregularities from the
crankshaft of the turbo engine at low RPMs
results in greater chain forces in the
balancer shaft chain drive. The crank
oscillation angle of the turbo engine is 2°.
Bow springs have been integrated into the
sprocket wheel hub. They decouple the
input shaft of the balancer shaft module
from the crankshaft. This is similar to a dual-
mass flywheel.
