18259-39 Washer spring cover

This .020-inch paper washer from James Gaskets is a precise fit for the spring covers on 1939 to 1948 74-inch and 80-inch Flathead models. It is designed as a high-quality replacement for OEM 18259-39 and 175-39C. In my experience, using the correct thickness of paper gasket is crucial for maintaining the right clearances and ensuring a leak-free assembly on these vintage engines. James Gaskets uses fiber-reinforced materials that stand up to the heat and oil of a working motor much better than generic alternatives. These washers are sold in a pack of 10, making them a practical choice for any mechanic working on classic Harley-Davidson Flatheads.
