Maintenance and Replacement of Gaskets
Figure 4 shows the features of a JTEKT oil seal.
Regular inspection and maintenance of spark plug wires and spark plugs are essential to identify signs of wear, damage, or deterioration. Proper replacement of worn or fouled spark plug wires and spark plugs is crucial for maintaining the efficiency and reliability of the ignition system. Adhering to recommended service intervals and using high-quality replacement components are essential for optimizing the performance and longevity of the vehicle's ignition system.
Oil seals are installed beside the bearing while the flexible lip is pressed against the rotating shaft. The casing pressing into the housing holds the seal in place. The sealing lip is essentially lubricated to minimize the risk of overheating due to the generated friction.
As the pressure increases, the radial load and the friction of the sealing lip increase in contact with the shaft. As with temperature, each oil seal has a recommended pressure for optimum performance. Excessive pressure causes the seals to wear more quickly and consequently have a shorter life.

A typical oil seal consists of three common parts: an outer ring, the sealing element, and a spring. The exterior metal ring component provides strength and rigidity to the oil seal in the bore or recessed groove. Attached to that ring is the sealing element. This flexible interior component of the oil seal, the O-ring, prevents any fluid leaks between the shaft and housing. A spring ensures the constant pressure that deforms the O-ring, creating a reliable seal while maintaining radial force on the shaft.
