New features
A balancer shaft module with two counter-rotating shafts provides an effective reduction in second-order
engine oscillations.
The module is a built-up module consisting of two housing halves.
The balancer shafts rotate in bearing bushes and are driven by the crankshaft at double the crankshaft speed
via a sleeve-type chain. The second shaft is driven in the opposite direction to the crankshaft via a pair of
gears. This balancer shaft connects to a hexagon bolt at the front end and also drives the oil pump.
