Here are some signs that may indicate a problem with the crankshaft bearings:

Power reduction: Damage to the crankshaft bearings can directly lead to a significant decrease in the engine's output power.
Abnormal noise: If there is abnormal noise caused by metal collision or friction during engine operation, it may be a signal of damaged crankshaft bearings.
Engine overheating: Bearing damage may reduce lubrication, leading to a sharp increase in engine temperature and even overheating.
Decreased fuel efficiency: Poor condition of crankshaft bearings can reduce the operating efficiency of the engine, leading to an increase in fuel consumption.
Startup issue: Bearing damage can sometimes affect the normal operation of valves, leading to difficulty in starting the engine.
Unstable Idle Speed: If the engine is unstable at idle speed, it may be caused by damage to the crankshaft bearings, resulting in unstable operation.

Connecting Rod Bearings play an important role in engines, as they can reduce the wear of the crankshaft pin.
By connecting the crankshaft pin to the shaft, they effectively reduce the friction between the crankshaft pin and the shaft, thereby extending the service life of the crankshaft pin.
At the same time, connecting rod bearings can improve the performance and efficiency of the engine, reduce engine noise and vibration, and ensure the normal operation and stability of the engine.
Therefore, the design and manufacturing of connecting rod bearings need to be very strict to ensure their quality and performance.
