Its robust construction, precise dimensions, and advanced material composition make it an essential part for maintaining engine integrity and preventing oil leakage.

Key Features and Specifications

• Material Composition: Made from premium fluorinated rubber (FPM) or high‑grade synthetic elastomer, ensuring excellent resistance to heat, pressure, and chemical exposure.
• Dimensions: Inner diameter, outer diameter, and width are engineered to match the exact specifications of the crankshaft seal groove for a perfect fit.
• Temperature Range: Operates effectively from -40 °C to +200 °C, accommodating extreme operating conditions in automotive and industrial engines.
• Pressure Rating: Capable of withstanding internal pressures up to 150 bar, providing reliable sealing under high‑pressure environments.
• Compatibility: Designed for use on a variety of crankshafts, including those found in Volvo B6 7.1 (1991–2006), Renault trucks FL D6B and FL II D7E240 Corteco, as well as other commercial vehicles and machinery.

Applications Across Industries

The versatility of the Elring 084.920 Seal Ring is evident in its widespread adoption across multiple sectors:

• Automotive: Integral to the crankshaft seals of passenger cars, light trucks, and heavy-duty vehicles, ensuring oil retention and preventing contamination.
• Commercial Vehicles: Used extensively in Volvo and Renault truck engines, where durability and reliability are paramount for long service life.
• Aviation & Marine: Suitable for high‑performance engines that demand superior sealing under variable pressure and temperature conditions.
• Industrial Machinery: Employed in generators, compressors, and other equipment where crankshaft integrity is critical to operational efficiency.

Installation Guidelines

Proper installation of the Elring 084.920 Seal Ring ensures optimal performance and longevity:

1. Preparation: Clean the crankshaft seal groove thoroughly to remove any debris, oil residue, or old gasket material.
2. Alignment: Position the seal ring so that its inner diameter aligns precisely with the crankshaft bore. Use a torque wrench to apply the recommended tightening sequence if applicable.
3. Sealing Surface Contact: Ensure that the sealing surface of the ring makes full contact with the groove walls, avoiding any gaps that could lead to oil leakage.
4. Verification: After installation, perform a leak test under operating pressure and temperature conditions to confirm seal integrity.

Maintenance and Longevity Tips

While the Elring 084.920 Seal Ring is engineered for durability, following these maintenance practices can extend its service life:

• Regularly inspect the seal during routine engine overhauls for signs of wear or deformation.
• Avoid exposing the ring to incompatible chemicals that could degrade the elastomeric material.
• Maintain proper oil viscosity and cleanliness; contaminated oil can accelerate seal wear.
• Store spare rings in a cool, dry environment away from direct sunlight to preserve material properties.

Technical Support and Resources

For detailed technical data, including exact dimensional charts, torque specifications, and compatibility matrices, consult the manufacturer’s technical documentation. This information is essential for engineers and technicians who require precise integration of the Elring 084.920 Seal Ring into complex engine assemblies.

Conclusion

The Elring 084.920 Seal Ring stands out as a reliable, high‑quality component for sealing crankshaft applications across automotive, commercial, and industrial sectors.
