Cometic Primary Service Kit For Harley Big Twin 1965-1985
Cometic Primary Service Kit: The Professional Seal for Classic Big Twins
When servicing a classic 1965–1985 Harley-Davidson Big Twin, the biggest challenge is often achieving a perfect seal on aging primary covers. The Cometic Primary Service Kit solves this with industry-leading materials. Designed for Shovelhead and early Evolution 4-speed models, this kit replaces the unreliable paper and cork gaskets of the past with modern, high-performance technology that withstands the vibration and heat of a classic V-Twin.
AFM (Aluminum Foam Material) Technology
The centerpiece of this kit is the AFM primary gasket. This material features an aluminum core coated with a chemically blown synthetic rubber. This unique construction provides:
- Superior Conformability: The rubber foam flows into surface irregularities and scratches on old aluminum covers, ensuring a perfect seal even on warped or pitted surfaces.
- High Torque Retention: The aluminum core prevents the gasket from “creeping” or squeezing out under bolt pressure, meaning you won’t have to re-torque your primary bolts constantly.
- No Sealer Required: Unlike OE-style gaskets, Cometic AFM gaskets are designed to be installed dry, making future teardowns significantly cleaner and easier.
Comprehensive Service Components
This kit isn’t just a perimeter gasket; it includes the essential seals required for a full primary service. Depending on your specific year and model, the kit typically includes:
- Outer Primary Gasket: High-performance AFM construction for a leak-free outer cover.
- Derby and Inspection Cover Gaskets: Precision-cut for the classic 3-hole or 4-hole patterns used during this era.
- Oil Seals: Including the crankshaft/compensator seal and starter drive seals where applicable.
- Lock Washers/O-rings: All necessary hardware seals to prevent “weeping” from bolt holes.
