Cometic Derby Cover Gasket Harley-Davidson Big Twin

The Cometic Derby Cover Gasket for Harley-Davidson Big Twin engines seals the derby cover (also called the primary inspection or clutch inspection cover) against the primary housing. It is a direct replacement for the factory gasket and helps keep primary fluid in and contaminants out.

Key Features:

• Made by Cometic, a U.S. gasket manufacturer that designs for modern V-Twin engines
• Designed as a replacement for the OEM derby cover gasket or O-ring
• Gives a consistent seal at the derby cover to help prevent primary leaks
• Suits routine primary service, clutch maintenance and engine rebuilds
• Several variants are available to match different Big Twin derby cover designs

Cometic applies its gasket technology and manufacturing know-how to V-Twin applications. A fresh derby cover gasket is inexpensive insurance whenever the cover is removed for inspection or service.
