- Stiff Steering Wheel Difficulty turning the steering wheel can suggest a lack of fluid or a failing power steering pump.
- Remember, while you can save money by doing this task yourself, if you're unsure or uncomfortable, it's best to seek professional assistance. Regular spark plug replacement, as recommended by the manufacturer (usually every 30,000 to 100,000 miles), can help prolong your engine's life, maintain optimal performance, and potentially avoid more costly repairs down the road.
- Replacing a car oil gasket is a specialized task that requires precision and expertise
The best seal performance is achieved when close shaft and bore tolerances are present. Other factors include shaft eccentricity, end play and vibration.


Indeed, when installing this oil seal, the oil sump must be installed using silicone seal. Removal of the old seal and oil sump is necessary, otherwise the oil seal cannot be fitted properly either. If these steps are not followed, leakage is inevitable.

5. TYPES OF FLUID: Numerous oil seals can interact with oils, fuels, grease, water and more. However, know exactly what type of fluid the rotary shaft seal will be in contact with will ensure the longevity of the seal and the machinery.
How do oil seals work?
ERIKS type M (type B according to the DIN standard) has a single metal casing and rubber sealing lip. Since the casing is made of metal, it must be fitted in a well-finished, undamaged groove. Large volumes of oil seals with metal casings are often cheaper, which is why they are often used as original equipment in machines. However, if an oil seal has to be replaced, types with a rubber exterior (type R or RST) are easier to fit. Type MST is similar to M and commonly used. The difference is the dust lip in the MST oil seal that prevents dust and dirt reaching the sealing lip, and extends its service life in dusty environments.
PTFE, which is used in the well-known brand Teflon®, is less commonly used, but it is the preferred material for specific rotating seals in the chemical, food and pharmaceutical industries. This material is notable for having a very low frictional resistance and the best chemical resistance. It can also withstand a very wide range of temperatures in these types of seals; -80 ˚C to 200 ˚C. The shafts on which oil seals with PTFE lips are used require a harder and finer finish. Something like an axle sleeve can also be used to meet this requirement.
There are several materials used to manufacture oil seals. They are discussed below.
