4. Remove Old Seals Once you can access the seals, carefully remove the old seals using appropriate tools. Avoid scratching or damaging the surfaces where the new seals will be placed.

An oil seal, also known as a lip seal or rotary seal, is a device used to seal the junction between stationary and moving parts in machinery. Its primary function is to prevent the leakage of lubricants, such as oil or grease, while simultaneously barring dirt and contaminants from entering the system. This is crucial for maintaining the efficiency and longevity of mechanical components.

The design often includes a lip or multiple lips that create an effective barrier against leaks. Depending on the application, some oil seals are equipped with spring mechanisms that enhance their sealing capabilities, allowing for optimal performance in dynamic operating environments.
