Which risk increases dramatically when harmonic dampers fail on diesel crankshafts?

A)Torsional resonance and crankshaft failure✓

B)Excessive connecting rod bearing wear

C)Reduced valve timing accuracy

D)Increased fuel injector carbon buildup

💡 Explanation

Torsional resonance and subsequent crankshaft failure will occur because the harmonic damper normally provides **tuned mass dampening**, which neutralizes destructive vibrations at critical engine speeds; therefore resonance damage is prioritized, rather than bearing wear which represents a distinct issue.
