ELRING 023.940 Engine Blocks: Precision Sealing for High‑Performance Crankshafts

The ELRING 023.940 is a premium crankshaft oil seal engineered to deliver reliable sealing performance in a wide range of automotive powertrains. Designed with advanced materials and meticulous manufacturing tolerances, this component protects the crankshaft from oil leakage while maintaining optimal engine efficiency.

Key Functional Attributes

• Material Excellence: Constructed from high‑grade PTFE (polytetrafluoroethylene) combined with reinforced elastomeric layers, ensuring exceptional resistance to heat, pressure, and chemical exposure.
• Dual‑End Design: Features a rear crankshaft oil seal configuration that secures the oil passage at both the transmission end and the timing side, preventing cross‑contamination between engine compartments.
• Precision Dimensions: Standardized to fit a broad spectrum of vehicle models—including Ford, Mazda, Volvo, Jaguar, Land Rover, and Audi—thanks to its adaptable inner diameter (88 mm) and outer width (170–180 mm).
• Enhanced Seal Life: The PTFE core provides low friction and high wear resistance, extending service intervals even under aggressive operating conditions.

The ELRING 023.940 is engineered to match a diverse array of engine architectures:

Installation Highlights

Installing the ELRING 023.940 involves a straightforward procedure that can be completed by experienced technicians or knowledgeable DIY enthusiasts:

1. Remove the Old Seal: Carefully extract the existing crankshaft seal using a suitable seal puller, ensuring no damage to surrounding components.
2. Clean the Crankshaft: Thoroughly wipe the shaft and housing with a solvent‑free cleaner to eliminate oil residues and debris.
3. Position the New Seal: Align the PTFE core with the crankshaft bore, then slide the seal into place, ensuring it sits flush against the housing walls.
4. Secure the Housing: Tighten any retaining bolts or clips according to manufacturer specifications, maintaining even pressure across the seal surface.
5. Verify Seal Integrity: After reassembly, perform a leak test by running the engine at low RPM and inspecting for oil seepage around the crankshaft.

Performance Benefits

• Oil Containment: Prevents oil from escaping into the timing chain area or transmission, preserving lubrication integrity.
• Reduced Maintenance: The durable PTFE core minimizes wear, lowering the frequency of seal replacements.
• Engine Longevity: By maintaining proper oil pressure and preventing contamination, the seal contributes to extended engine life.
• Noise & Vibration Reduction: The elastomeric layers absorb minor vibrations, resulting in smoother operation.

Quality Assurance & Standards

The ELRING 023.940 is manufactured under stringent quality control protocols that align with ISO and automotive OEM standards. Each seal undergoes dimensional verification, pressure testing, and material composition analysis to guarantee consistent performance across all units.

Maintenance Tips for Optimal Seal Life

• Regular Inspection: Check the crankshaft housing for signs of oil leakage during routine maintenance intervals.
• Avoid Over‑Torqueing: When reinstalling, adhere to specified torque values to prevent seal deformation.
• Use Compatible Oils: Employ engine oils that meet or exceed the viscosity and additive specifications recommended by the vehicle manufacturer.
• Keep Housing Clean: Prevent accumulation of dirt or metal shavings, which can compromise seal integrity.

Conclusion

The ELRING 023.940 Engine Block Seal stands out as a reliable, high‑performance solution for protecting crankshaft oil passages across an extensive range of automotive platforms. Its PTFE core, precise engineering, and broad compatibility make it the preferred choice for both OEM replacements and aftermarket upgrades.

By integrating this seal into your vehicle’s maintenance routine, you ensure sustained engine efficiency, reduced risk of oil contamination, and prolonged component life—key factors that contribute to overall vehicle reliability and performance.
