Frequently Asked Questions
C9306 is a cam cover gasket for specific Harley‑Davidson Sportster Evolution engines. Confirm fitment by checking your year, model, and engine against the Cometic catalog or by cross‑referencing your OEM cam cover gasket part number.
Many Cometic AFM cam cover gaskets are designed to be reusable if not damaged during removal, but Cometic only recommends reuse when the gasket is visually intact and clean. Always inspect for tears, compression set, or distortion before reusing.
Generally, Cometic cam cover gaskets are designed to be installed dry on clean, flat surfaces. Only use sealant if specifically called for by the Harley‑Davidson service manual or Cometic’s documentation.
Replacing the cam cover gasket itself does not change cam timing, but removing the cam cover can expose timing marks and components. Follow the service manual closely during disassembly and reassembly to avoid moving any components unintentionally.
On most Sportster models the cam cover can be removed with the engine in the frame. However, access is tight; refer to the Harley‑Davidson service manual for your specific year to see what needs to be removed for clearance.
Installation Guide
Difficulty
Medium
Est. Time
1 hr 0 min
Tools Required
- Basic SAE socket set
- Allen/Hex keys or Torx bits (depending on model’s cam cover fasteners)
- Inch‑pound or low‑range foot‑pound torque wrench
- Gasket scraper or plastic razor blade
- Brake cleaner or solvent and clean rags
- Thread locker (medium strength) if specified by service manual
- Service manual for torque specs and sequence
Pro Tips
- Dry‑fit the gasket on the cover first to confirm orientation and bolt‑hole alignment.
- Thoroughly degrease both mating surfaces and blow out bolt holes so torque readings are accurate.
- Snug all bolts in a criss‑cross pattern, then final‑torque in stages to the spec in the Harley‑Davidson service manual.
- After the first heat cycle, inspect for any light weeping around the cam cover and re‑check torque if the manual allows.
- Photograph cable/hose routing and any timing mark locations before disassembly to make reassembly easier.
Common Mistakes to Avoid
- Reusing old gasket surfaces without fully removing previous gasket material and sealant
- Over‑tightening cam cover bolts and crushing the gasket
- Not following the factory torque sequence, causing leaks or warping
- Pinching the gasket by hanging it on dowel pins or misaligning bolt holes
- Using RTV silicone on a gasket that is designed to be installed dry (unless the manual specifically calls for a sealant)
Comparison vs Stock/OEM
Cometic gaskets are generally viewed as equal or superior to OEM Harley‑Davidson gaskets in sealing performance, especially for performance or high‑heat applications.
Improvements
- High‑quality materials optimized for heat and oil exposure typical of Harley V‑twin engines
- Better resistance to crushing and extrusion compared to some paper‑style OEM gaskets
- Often reusable if not damaged, reducing long‑term service costs
Considerations
- Must have clean, flat mating surfaces and correct torque to realize benefits
- Always confirm thickness; a significantly different thickness than OEM could very slightly change component spacing, though this is rarely an issue for cam covers.
Durability & Warranty
Expected Lifespan
Typically lasts many years and tens of thousands of miles when installed correctly on clean, flat surfaces and not disturbed.
Warranty
Standard Cometic limited manufacturer warranty against defects in materials and workmanship; exact terms depend on distributor and current Cometic policy.
Maintenance
No direct maintenance; periodically inspect for oil weeping around the cam cover as part of normal service checks.
