Camshaft Adjustment Actuators
F366 – F373
The camshaft adjustment actuators are electromagnetic
solenoid-type actuators. Two actuators are used per
cylinder. One actuator moves the cam element on the
camshaft for large valve lift. The other actuator resets the
cam element for small valve lift.
Each actuator is attached externally to the cylinder head
cover by a bolt. They are sealed with O rings. When the
actuator is activated by the ECM, a metal pin engages the
displacement groove in the cam element, thereby moving
the other cam lobe into position.
