When replacing spark plugs, it is important to follow the manufacturer's recommendations for the correct type and gap setting.

Oil seals go by many names, such as shaft seals, dirt seals, grease seals, lip seals, and many other variations of these. They are essentially simple devices used in rotary shaft equipment to prevent lubricant from escaping and for excluding contaminants such as dust, dirt and water.
