• Crankshaft bearings should be kept sufficiently lubricated and cooled to avoid overheating and damage.
• Check crankshaft bearing wear and bearing clearance regularly, adjust or replace if necessary.
• If the vehicle is hit, the crankshaft bearing should be checked for damage and repair measures should be taken in time.
• When the crankshaft bearing has abnormal noise or vibration, it should be stopped immediately for inspection and maintenance.
• Incorrect engine oil pressure or excessive oil temperature can lead to crankshaft bearing failure, so special attention should be paid to changes in these parameters.
