Overall, black spark plugs are a common issue that can occur in internal combustion engines. It is important to regularly inspect and replace spark plugs to ensure optimal engine performance and prevent more serious issues down the line. By addressing the root causes of black spark plugs, such as a rich air-fuel mixture, oil leakage, and overheating, you can keep your engine running smoothly and efficiently.
If this is not possible, you may be able to fit the lower retaining bolt into the upper mounting support, to hold the engine level. Or the gearbox may have to be jacked up and supported.
Aflas is created from fluoroelastomers (FKM), providing the following benefits:
Oil seals come in a wide range of types, and they also have various sizes.
When selecting the right oil seal for your machine from among these many varied types of oil seals, the following two criteria are very important.
Type code
Oil seals come in various shapes to fit the machines and substances to be sealed.
Figure 2 shows the structure and the names of the various components of the most typical oil seal.
The functions of the various components are also indicated in Table 1.
Foam inhibitors: This additive does exactly what it sounds like. Foam inhibitors keep motor oil from forming foam and bubbles. If foam and bubbles were to form, the oil would be unable to coat the important parts of the engine and keep it cool.
Viton Oil Seals - A synthetic rubber and fluoropolymer elastomer, Viton is used to make oil seals that provide resistance in both high temperature, up to 250°C and low compression set components. They also offer a high resistance to chemicals and abrasions, so they can be used in elements that regularly interact with petroleum and solvents.
