Cometic Primary Cover Gaskets

11 products — part of all Primary Cover Gaskets

Cometic primary cover gaskets give Harley-Davidson owners precision-cut seals for one of the most leak-prone joints on a V-twin — the junction between the primary cover and the engine cases. The primary chaincase holds the clutch, primary chain and compensator sprocket in an oil bath, and a leaking primary gasket allows that oil to track down the left side of the engine onto the inner frame, exhaust and rear tyre. Cometic manufacture their primary cover gaskets from materials specifically selected for compatibility with Harley-Davidson primary oil chemistry and the significant heat cycles the chaincase generates during riding. Their dimensional accuracy ensures a consistent, even seating surface that compresses correctly without over-torqueing the cover bolts. Fitment covers the main Big Twin primary cover designs across Evolution, Twin Cam and Milwaukee-Eight applications. Iron City Motorcycles, Leeds' authorised Harley-Davidson dealer, stocks Cometic primary cover gaskets as part of a comprehensive drivetrain sealing range.
