Engine Bearing

The engine bearing is a key component in the engine. It mainly plays the role of supporting and reducing friction, ensuring that the rotating parts inside the engine (such as the crankshaft, connecting rod, etc.) can run smoothly and efficiently.

Supporting rotating shafts: ensuring that the shaft remains stable when rotating at high speeds.
Reducing friction: reducing friction between the shaft and the bearing through lubrication to improve efficiency.
Bearing loads can handle radial and axial loads and prevent shaft offset or deformation.
Extending life: reducing wear and extending the service life of the engine.
Reducing noise and vibration: helps reduce noise and vibration during operation and improves stability.

To determine whether the engine bearing needs to be replaced, you can comprehensively consider the following aspects:

1. Sound and vibration： Abnormal sound: sharp friction, humming, or knocking sounds during engine operation

Increased vibration: engine vibration increases significantly and exceeds the normal range

2. Temperature and temperature changes： Abnormal temperature increase: abnormal temperature increase at the engine bearing part, or sudden temperature fluctuations

3. Lubrication condition: Grease deterioration: grease turns black, dries or has impurities; insufficient lubricating oil or leaks

4. Appearance inspection: Wear, cracks, peeling, or deformation; rust and corrosion

5. Running performance: Decrease in running efficiency: engine efficiency decreases significantly, or running is unstable, such as axial or radial displacement, increased vibration, etc., which may be caused by bearing damage.

6. Maintenance records and life expectancy

In summary, to determine whether the engine bearing needs to be replaced, it is necessary to comprehensively consider multiple factors such as sound, vibration, temperature, lubrication condition, appearance, running performance, maintenance records and life expectancy. When any abnormal signs are found, further inspection should be carried out in time and necessary maintenance or replacement measures should be taken.
