- In conclusion, the main bearing oil seal is a vital component in the engine's lubrication system. Its ability to prevent oil leakage while allowing the rotation of the crankshaft is essential for the smooth operation and extended service life of the engine. By understanding the design, materials, and compatibility requirements of the main bearing oil seal, engine owners can ensure the longevity and reliability of their vehicles.
- There are also shaft repair sleeves that can add a “new surface” to the shaft. Measuring a few thousandths of an inch in thickness, they cover shaft flaws so the seal can make proper contact with the surface.
- In conclusion, the rear valve cover gasket, though seemingly insignificant, is a critical part of an engine's health. Its function is not just to prevent oil leaks but also to maintain the cleanliness and lubrication necessary for smooth engine operation. Hence, understanding its importance and ensuring its proper maintenance is a must for every vehicle owner or mechanic. Remember, prevention is always better than cure, and a healthy engine starts with a reliable rear valve cover gasket.
Fluoro rubber (FKM)
FKM or FPM, which is in well-known brand Viton™, can withstand higher liquid temperatures of up to 180 ˚C. FKM is highly resistant to strong acids and bases, as well as to synthetic oils and greases. Glycol-based oil and grease, however, can also damage FKM.
Regular inspection and replacement of oil seals are also necessary to prevent leakage and maintain the efficiency of the machinery. Over time, oil seals can wear out due to constant friction and exposure to harsh conditions, leading to leaks and potential damage to the equipment. By monitoring the condition of oil seals and replacing them as needed, operators can prevent costly downtime and repairs.


The first step in installing oil seals is to clean the surface where they will be placed. Dirt, debris, and other contaminants can cause the oil seal to become damaged or misshapen, leading to leaks. Clean the surface with a solvent or soap and water, and make sure it is completely dry before installing the oil seal.
