Lip seals

Sealers in scooter, motorcycle, quad

Sealers are used to prevent oil and other fluids from leaking from various components in a scooter, motorcycle or quad bike. They are usually located where two metal parts meet, such as between the crankcase and the cylinder head. Typical types of sealers include oil seals, which keep oil inside, and valve stem seals, which prevent oil from entering the combustion chamber. It's important to check and maintain engine seals regularly to make sure they are in good condition and not leaking. If a sealer is leaking, it may need to be replaced to prevent further damage to the component it works with.

Why do the sealers wear out?

There are several factors that can cause oil seals to fail, including:

Age and wear: Over time, oil seals can become brittle and lose their elasticity, making them less effective at sealing the gap between the rotating shaft and the stationary housing of the engine.
Exposure to heat: High temperatures can cause oil seals to dry out, crack, and lose their ability to seal effectively.
Exposure to chemicals: Certain chemicals, such as solvents, acids, and fuels, can cause oil seals to degrade and lose their ability to seal effectively.
Improper installation: If oil seals are not installed correctly, they may not be able to seal properly and may fail prematurely.
Contamination: debris and dust can get into the seal and cause wear on the seal and the shaft.
Incorrect lubrication : Lack of lubrication or using the wrong type of lubricant can cause oil seals to wear out prematurely.
Excessive vibration or movement of the shaft: This can cause the oil seal to become loose and leak.
Mechanical damage: oil seals can be damaged by impact or other forms of mechanical damage.

It's always best to consult with a professional mechanic or the owner's manual for your specific motorcycle to determine the cause of oil seal failure and to ensure that the correct steps are taken to prevent future failures.

What are the consequences of not replacing leaking oil seals?

The consequences of not replacing a leaking oil seal can be serious and can lead to damage to the engine and other components of your motorcycle. Some of the most common consequences of not replacing a leaking oil seal include:

Loss of oil pressure: A leaking oil seal can allow oil to escape from the engine, which can lead to loss of oil pressure. This can damage the engine and other components, as well as lead to decreased performance and increased fuel consumption.
Low oil level: A leaking oil seal can cause the oil level in the engine to drop, which can lead to damage to the engine and other components.
Oil contamination: If oil leaks from under the seal, it can contaminate other engine parts, such as the air filter, which can cause further damage to the engine.
Fire hazards: An oil leak can also lead to a fire hazard, as oil can accumulate on hot engine parts or the exhaust.
Reduced performance: Leaky seals can cause reduced performance and power due to low oil pressure and oil loss.
