Top 10 Auto Oil Seal Maintenance Mistakes That Cause Engine Damage

图片
  When it comes to engine longevity, few components are as overlooked yet critical as the   auto oil seal . A small failure here can lead to devastating engine damage, expensive repairs, and even complete engine failure. As specialists in automotive maintenance and engine performance, we have identified the top 10 oil seal maintenance mistakes that car owners and even some technicians often make. Avoiding these pitfalls is essential to preserving your engine’s health. 1. Ignoring Early Signs of Oil Leaks One of the most common mistakes is ignoring minor oil leaks around the seals. Drivers often delay maintenance until the leak becomes obvious. By this point, the engine may have suffered internal damage due to inadequate lubrication or contamination. Warning signs to watch for: Dark spots under the vehicle Burning oil smell Low oil levels without visible spills Pro tip: Inspect the engine bay monthly and after long drives for oil residue. 2. Using Low-Quality or Incorrect Oil S...

Do you know the cost of repairing oil leaks?

图片
  The cost of repairs is probably one of the biggest factors in the cost of owning a vehicle. Buying a vehicle with poor fuel mileage will certainly cost you more, but the cost of major repairs usually adds up to the biggest expense. Depending on their design alone, some vehicles cost more to maintain. For example, rear-wheel drive cars are more expensive to maintain than front-wheel drive cars because you need to change the transmission fluid and rear differential fluid regularly, while front-wheel drive cars only need to change the transmission fluid because there is no separate differential. As an  oil seal  manufacturer, we have always focused on helping you deal with oil leaks. HONGLEI presents in this article about the cost of repairing oil leaks.     What Causes Oil Leaks   Engine oil leaks can be caused by a variety of reasons, but most leaks are caused by a degraded  engine gasket  or poor oil seal. The cost of an engine oil leak repair i...

Description of Oil Seal Common Raw Materials

图片
  Oil seal   is the customary name of general seals, which is simply the seal of lubricating oil. It is used to seal grease (oil is a common liquid substance in the transmission system, also refers to the general meaning of liquid substances) mechanical components, it will drive parts in need of lubrication and output parts of isolation, so as not to let lubricant leakage. Static and dynamic seals (general reciprocating motion) are called oil seals with seals. The representative form of oil seal is TC oil seal, which is a double lip oil seal with self-tightening spring completely covered by rubber. Generally speaking, oil seal often refers to this TC skeleton oil seal. Common materials for oil seals are: Nitrile rubber (NBR), fluorine rubber(FKM), silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene and so on.   1. NBR   It has good heat resistance, wear resistance, resistance to various lubricants, greases, oil and gas mixtures, suitable for temper...

9 Factors in Choosing an Oil Seal

图片
  From  Oil Seal Manufacturers , we know that the primary causes of external lubricant leakage in pumping systems, hydraulic presses, gearboxes and tanks are incorrect selection, improper application, improper installation and improper maintenance of sealing systems. These problems can be overcome by better understanding the types of seal materials available, redefining the selection process, and consistently applying sound replacement and maintenance practices.     There are a number of variables that must be considered when selecting oil seals. When specifying oil seals, designers and maintenance engineers must evaluate nine factors:   Shaft Speed The maximum shaft speed allowed is determined by the shaft finish, runout, concentricity of the housing bore and shaft, the type of fluid being sealed, and the type of oil seal material.   Temperature The temperature range of the mechanism where the oil seal is to be installed must not exceed the temperature ran...

What Materials Are Available for Oil Seals

图片
  An   oil seal   is also known as a rotary shaft seal, shaft seal, lip seal, elastomeric lip seal, or any variation of these. It is a simple device used to remove dust, dirt, water or any other contaminants while retaining the lubricant in a rotary shaft device. Often, it has been developed as a way to protect rotating shaft bearings. The following shows the selection of  oil seal materials ​. 1,  Aflas,  temperature range between -10°C and +205°C, made of special fluoroelastomer (FKM), resistant to steam, petroleum, amine corrosion inhibitors and hydrogen sulfide. 2, Carboxylated Nitrile , temperature range -55°C to +135°C. Carboxylated Nitrile seals are made of a low temperature resistant compound that also has excellent abrasion resistance. Resistant to water and oil, 3,  Viton , temperature range -20°C to +205°C, FKM fluorocarbon seals are highly resistant to solvents and petroleum oils. As a result, they are ideally suited for high temperature in...

  How important is the correct installation of  oil seals ? Even if the oil seal has been correctly selected and the grooves in the seal mounting area have been reasonably sized, but the seal has not been installed scientifically and correctly, there is no guarantee that it will perform 100% of its intended function.  Honglei  takes you through how the oil seal should be installed.   Valve Oil Seal   How should the oil seal be installed? 1.When installing the oil seal, the key should be removed first before installing the oil seal.   2.When installing the oil seal, apply oil or lubricant first and round off the shaft end and shoulder of the oil seal.   3.When installing the oil seal, be sure to make the lip end of the oil seal face towards the side of the oil being sealed, and avoid reverse assembly of the oil seal.   4.Assemble the oil seal with professional tools to avoid damage to the oil seal lip when the oil seal lip passe...

How to Quickly Repair a Bad Valve Seal?

图片
  If you suspect that you have a bad  valve seal , there are a few steps you can take to try to repair it:     Clean the valve and surrounding area Use a small brush or toothbrush to clean any dirt or debris from the valve and the area around it.   Apply a penetrating oil Spray or apply a penetrating oil, such as WD-40, to the valve stem and the surrounding area. This can help to loosen any stuck or seized parts and make it easier to remove the valve.   Remove the valve Use a valve removal tool, such as a valve spring compressor, to remove the valve from the engine. Be careful not to damage the valve or the valve seat while removing it.   Inspect the valve seal Once the valve is removed, inspect the seal for any visible damage or wear. If the seal is damaged, it will need to be replaced.   Replace the valve seal Use a seal replacement tool to remove the old seal and install a new one. Make sure the new seal is properly seated and aligned before re...
