Installation of Automobile Oil Seals

Before installation, the car oil seal should be appropriately coated with lithium ester containing molybdenum disulfide between the lips to prevent dry wear on the lips when the shaft starts instantly, affecting the interference of the lips. Assembly should be carried out as soon as possible. If the oil seal seat is not installed immediately, it is recommended to cover it with a cloth to prevent foreign objects from adhering to the oil seal. The hands or tools used to apply lithium grease must be clean.

2. The oil seal should be installed flat without tilting. It is recommended to use hydraulic equipment or sleeve tools for installation. The pressure should not be too high, and the speed should be uniform and slow.

3. When installing automotive oil seals, oil or lubricating oil should be applied and the shaft end and shoulder should be rounded.

When installing the oil seal, be sure to face the lip end towards the side of the sealed oil, and avoid reverse assembly.

5. When installing the oil seal into the seat hole, special tools should be used to push it in to prevent deviation.

6. Various measures should be taken to prevent lip damage at the threads, keyways, splines, etc. where the oil seal lip passes through, and special tools should be used for assembly.

7. When disassembling the oil seal, avoid damaging the surface inside the cavity and the surface of the shaft.

8. The used oil seal, even if it has a good appearance, cannot be used anymore and must be replaced with a new one.

9. When there are scratches or rust on the surface of the shaft, it must be repaired.

When installing a new oil seal, in order to keep it away from the old lip contact area, a gasket should be used to avoid the original friction marks.
