Lack of oil seal is the main factor causing oil leakage. When the shaft wears and forms a groove, even if the oil seal is replaced with a new oil seal, the contact pressure between the oil seal lip and the shaft is decreased, resulting in too small interference between the oil seal lip diameter and the shaft diameter after installation.

Now take the S195 diesel engine crankshaft oil seal as an example, and analyze the main reasons for its lax seal:

① Poor quality of oil seal manufacturing;

②The shaft or bearing is of poor quality;

③Improper use and maintenance;

④Improper installation;

⑤Improper storage, adversely affected by environmental pollution
