Next, apply a small amount of grease to the seal lip(s) and the area of the shaft in contact with the seal. When using a double-lip seal, fill the small cavity between the two lips with grease as well. This both protects the lips during initial installation and break-in, and also acts as another barrier keeping contaminants out. When installing rubber-coated seals, apply lubricant to the outside diameter as well. This will help prevent the seal from rebounding or backing out from its mounting place.
3. Low compression set High temperature rubber gaskets have low compression set, which ensures that they maintain their shape and seal effectively over time.

Another benefit of twin spark plug technology is enhanced engine durability. With two spark plugs firing simultaneously, the workload is evenly distributed, reducing the wear and tear on individual components. This results in a longer lifespan for the engine and its components, ultimately saving the driver time and money on maintenance and repairs.Thoroughly clean the sleeve at the back of the pulley, and look for any roughness on it where it touches the seal. If necessary, smooth it with fine wet-and-dry abrasive paper.
