■Dispersants: This is your oil’s magic ingredient. It gives your oil the ability to absorb and hold solid contaminants so that they don’t damage the engine.

Wipe the head and block absolutely clean with a cloth moistened with petrol.

Under the action of the skeleton oil seal, the rigidity of the oil film just makes the oil film and the air contact end form a crescent surface, which prevents the leakage of the working medium and realizes the sealing of the rotating shaft. The sealing ability of the oil seal depends on the thickness of the oil film on the sealing surface. If the thickness is too large, the oil seal will leak; if the thickness is too small, dry friction may occur, causing the oil seal and shaft to wear; if there is no oil film between the sealing lip and the shaft, it is easy to cause heat and wear. . Therefore, when installing, it is necessary to apply some oil on the sealing ring, and at the same time ensure that the skeleton oil seal is perpendicular to the axis line. If it is not perpendicular, the sealing lip of the oil seal will drain the lubricating oil from the shaft, which will also lead to excessive sealing of the lip. wear. During operation, the lubricant in the casing seeps out a little, so that it is ideal to form an oil film on the sealing surface.

Runouts need to be minimized. The most common causes of the center of rotation movement are shaft whip and bearing wobble. The issue is even worse when there’s misalignment. Contrary to widespread assumption and practice, misalignment cannot be corrected or made up for by using flexible couplings.

Pressure - Many oil seals can only withstand low-pressure applications, so understanding the compression set of your components is key.

Proper maintenance and regular inspection are vital for prolonging the service life of oil seals and preventing unplanned downtime. Here are some tips:

The block is unlikely to distort except after severe overheating, but check anyway using a steel ruler or similar high-quality straight-edge.
