NOTICE: PMD crank snout is in TENSION.
160ft-lbs pulling on the snout for TENSION, while the Balancer neck & timing gear are in COMPRESSION.
Thus, a faulty damper can allow a TORSIONAL harmonic to grow. That torsional growth can be seen to hammer at the snout key like an "air-gun" kicker. Such coustic activity will allow an existing gouge/crack in the Crank snout to propagate and peel apart.
Torsional harmonics: the force that rips crank snouts off.
Bending monents: the force that rips Rear Axle flanges. <-- how rare that is until wheel-hop TORSIONALS occur.
