Leather Oil Seals - Leather Seals, also known as Type L Oil Seals, are most common in components that are subject to dirt and poor lubrication. Since they come pre-lubricated and are able to absorb fluids, leather oil seals are able to provide sealing properties in conditions that synthetic rubber is unable to.

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. An oil seal’s most important function, however, is that it protects every type of ball, sleeve and roller bearing in the rotating shafts. The seals also prevent the integration of two different fluids that shouldn’t mix, such as oil and water.
Seals perform best when they are lubricated, however, some machines quickly go on dry spells. So, in cases like this, choosing a leather or PTFE seal is the right decision to make as both of them can function with less lubrication than other types of seals.

Mark the position of the rotor arm by lightly scratching a line on the distributor body. Disconnect the LT lead from the distributor body.
In addition to these standardised types, the following special types are also available:
