Which risk increases within a diesel engine when asymmetric crankshaft journal wear exceeds specified tolerances?

💡 Explanation

When asymmetric journal wear occurs, dynamic imbalance within the rotating crankshaft increases bending stress at the supporting main bearings, because the crankshaft's center of mass shifts unevenly. Therefore, elevated bearing fatigue results, rather than NOx, turbo issues, or injector clogging, which stem from independent factors.
