1. Inadequate seal kits are the main cause of oil leakage. When the shaft wears and forms a groove, and the seal kit cannot be seal even if the seal kit is replaced with a new one, it is because the contact pressure between the seal kit lip and the shaft decreases, resulting in too little interference between the seal kit lip diameter and the shaft diameter after installation. Taking the crankshaft seal kit of the S195 diesel engine as an example, the main reasons for its poor seal kit are:
① Poor quality of seal kit manufacturing;
② Poor shaft or bearing quality;
③ Improper use and maintenance;
④ Improper installation;
⑤Improper storage and adverse effects caused by environmental pollution.
2. Treatment of seal kit lip damage
(1) Lip damage:
(2) Wear of the shaft:
