Vibration Damper
Vibration Damper:
The vibration damper of the M73 is a new axially designed vibration damper.
The pulse wheel for sensing engine speed/reference is no longer on the vibration damper. A new incremental gear wheel is now mounted on the flywheel.
The hub and damper body are now integrated into one unit. To remove the vibration damper from the crankshaft, remove the center hex bolt.
Like the connecting rod bolts, always reinstall the vibration damper with a new bolt.
