What Happens When a Motorcycle Crankshaft Fails?
1 Answers
Motorcycle crankshaft damage manifests as follows: 1. Loud abnormal noises; 2. Increased likelihood of cylinder scoring; 3. Accelerated component wear; 4. Metallic "clanking" sounds when accelerating; 5. Noise volume increases with throttle opening. Causes of motorcycle crankshaft failure: 1. Repeated bearing seizure in main/connecting rod bearings, weakening support capacity; 2. Excessive clearance between adjacent main bearings; 3. Prolonged looseness due to excessive main bearing wear; 4. Severe end play or bearing seizure; 5. Final main bearing seizure or bearing rotation; 6. Excessive crankshaft deflection or misalignment; 7. Cylinder block deformation causing main bearing bore misalignment.
