Frequently Asked Questions
No. C9293 is designed for Evolution Sportster engines (generally 1986–2003 Sportsters). It will not fit Twin Cam, Milwaukee‑Eight, or Shovelhead/Bigtwin engines.
Yes. It is sold as a complete pushrod O-ring kit for one Evo Sportster engine, including upper and lower O-rings for all pushrod tubes.
No sealant is normally required. Install them clean, lightly lubed with engine oil, on clean mating surfaces. Sealant can interfere with proper compression and sealing.
Yes. Pushrod O-ring replacement is normally done with the engine in the frame, following the standard Sportster top‑end or pushrod‑service procedure.
If your bike uses adjustable pushrods or you disturb the rocker gear, you should follow the factory or pushrod manufacturer’s adjustment procedure during reassembly.
Installation Guide
Difficulty
Medium
Est. Time
1 hr 30 min
Tools Required
- Harley-Davidson service manual for applicable Sportster model
- Basic metric/SAE socket and wrench set
- Allen/hex keys (for rocker box and/or exhaust if removed)
- Torque wrench (inch‑lb and ft‑lb ranges recommended)
- Pushrod tube spring compressor or suitable tool
- Pick tool or small screwdriver (to remove old O-rings)
- Shop rags and brake cleaner or solvent (to clean sealing surfaces)
Pro Tips
- Lightly coat the new O-rings with clean engine oil to prevent binding and tearing during assembly.
- Inspect pushrod tubes for dents or corrosion; replace damaged tubes or leaks may persist.
- Replace all pushrod tube O-rings at once while you’re in there to avoid repeat tear‑down.
- Follow factory torque specs and tightening sequence for rocker boxes and related hardware.
- After first warm‑up and cool‑down, inspect for any weeping around the tubes and recheck fasteners.
Common Mistakes to Avoid
- Reusing old, hardened O-rings instead of replacing all of them
- Nicking or twisting the new O-rings during installation, which causes new leaks
- Not fully seating the pushrod tubes so the O-rings don’t compress evenly
- Incorrect pushrod adjustment after reassembly (on adjustable pushrods)
- Failing to clean old oil and debris off the sealing surfaces before installing the new O-rings
Comparison vs Stock/OEM
Functionally equivalent replacement for OEM Sportster pushrod tube O-rings, using high‑quality materials suited for V‑twin operating temperatures.
Improvements
- High‑quality elastomer (commonly Viton or similar) for better high‑temperature and oil resistance than many generic aftermarket seals
- Kit format ensures all necessary O-rings for a complete pushrod service are included
Considerations
- Designed as a stock‑style replacement; does not change performance, only improves sealing reliability when old OEM O-rings harden or crack.
Durability & Warranty
Expected Lifespan
Intended to last many years/ tens of thousands of miles under normal operating conditions, similar to or better than OEM pushrod O-rings.
Warranty
Subject to Cometic Gasket’s standard limited warranty against defects in materials and workmanship (details provided by manufacturer).
Maintenance
No regular maintenance required; inspect for seepage during routine oil changes and replace O-rings if any signs of hardening, cracking, or persistent oil leaks appear.
