Take extra care with a light alloy block or head. It is vital to avoid scratching the machined surface.
The oil seal is generally composed of three basic components: sealing element, metal shell and clamping spring.Types of oil seals include single and double lips, rubber or polymer, metal housing, spring loaded, and internal, external and axial guides.
Some aspects to consider when selecting this component are:
iridium spark plug. The advanced design of the spark plug ensures that the spark is generated more efficiently, resulting in better combustion and reduced emissions.The seal shown in Fig. 14.2 is a relatively simple design; most automotive seals are more complex. Dust lips are often used to keep outside contaminants away from the oil lip seals; such seals thus have undercuts that make demolding more difficult. Fluoroelastomer compounds used for such undercut shapes must have reasonably high elongation at break at molding temperatures to avoid tearing the part during demolding. The metal insert is often U-shaped, and stock may be molded to form a thin layer over the outside of the insert. Since both compression and injection molding methods are used, suppliers of fluoroelastomers for shaft-seal applications often must provide different versions of the same polymer composition-medium to high viscosity for compression molding, and low to medium viscosity for injection molding. Different precompounds may be necessary to accommodate relatively long compression-molding times at low temperature and very short injection-molding times at high temperature.
high pressure oil seals. O-Rings, V-Rings, and lip seals are common types, each with their own unique advantages. For instance, O-Rings are simple yet effective, while lip seals are ideal for high-speed applications due to their self-cleaning property.There are many different materials used to manufacture oil seals.
