Elring 223890 Small Parts – Cylinder Head Bolt Kit
The Elring 223890 is a high‑performance cylinder head bolt set designed for modern automotive engines. It features a female splined (Ribe‑CV®) design, ensuring precise torque distribution and long‑term reliability in demanding operating conditions.
Key Design Features
- Precision Machining: Each bolt is manufactured to strict tolerances, guaranteeing a perfect fit on the cylinder head and block interfaces.
- Ribe‑CV® Splined Interface: The splined connection provides excellent load transfer and reduces the risk of bolt loosening under high vibration.
- Corrosion Resistance: Coated with a durable anti‑rust layer, the kit remains reliable even in harsh environments or when exposed to road salts.
- Compatibility: Suitable for a wide range of vehicles including Audi, Volkswagen, Porsche, Bentley, and others that use the 223890 bolt specification.
Applications
The kit is engineered to fit engines that require the 223890 bolt size. Common applications include:
- Audi models such as A5, A6, Q7, RS5, and S4.
- Volkswagen vehicles including Touareg II and various engine families.
- Porsche models like Macan and Cayenne.
- Bentley and other high‑performance brands that adopt the same bolt standard.
Installation Guidelines
Proper installation is critical for optimal performance. Follow these steps:
- Preparation: Clean all mating surfaces thoroughly to remove oil, dirt, and old gasket material.
- Torque Sequence: Use a calibrated torque wrench and follow the manufacturer’s recommended sequence (usually a star pattern). Typical torque values range from 70 Nm to 120 Nm depending on engine specifications.
- Check Alignment: Ensure that each bolt is seated correctly before tightening. Misalignment can lead to uneven pressure distribution.
- Final Inspection: After all bolts are tightened, re‑check torque values after a short running period (e.g., 10 minutes) to account for any settling.
Performance Benefits
The Elring 223890 kit delivers several advantages over standard bolt sets:
- Enhanced Durability: The splined interface resists loosening, extending the service life of the cylinder head assembly.
- Improved Engine Efficiency: A tighter seal reduces compression loss and improves fuel economy.
- Reduced Maintenance: Corrosion‑resistant coatings lower the frequency of bolt replacement.
Quality Assurance
Elring employs rigorous quality control processes, including:
- Dimensional inspections using laser measurement systems.
- Material testing to verify hardness and tensile strength.
- Environmental stress screening to simulate real‑world operating conditions.
Conclusion
The Elring 223890 Small Parts Cylinder Head Bolt Kit is a reliable, high‑quality solution for automotive engineers and enthusiasts seeking superior performance and longevity. Its precise engineering, corrosion resistance, and broad compatibility make it an excellent choice for both OEM replacements and aftermarket upgrades.
