C9491 Oil seal starter shaft

This Cometic oil seal is designed for the starter shaft on late 1984–1988 5-speed Big Twin models. It is typically used in the rear of the inner primary housing to prevent primary fluid from escaping around the starter drive. Replacing OEM 12051, this seal is sold as a pack of 5, ensuring you have spares on hand for future service work. Cometic seals are manufactured to exacting standards to provide a long-lasting, tight fit that stands up to the constant movement of the starter shaft and the heat of the primary drive. It is a small but critical component for maintaining a dry and clean primary setup on mid-eighties Harleys.
