The Elring 266.340 Seal Ring is a high‑performance crankshaft oil seal designed to deliver reliable sealing for a wide range of automotive engines. Whether you are working on a Suzuki Vitara Grand, a Chevrolet Geo, a Maruti model, or any other vehicle that requires a crankshaft front seal, this component offers the durability and fitment precision demanded by modern engines.

Key Features & Technical Specifications

• Model Number: 266.340
• Dimensions: 45 mm (inner diameter) × 63 mm (outer diameter) × 7.5 mm (thickness)
• Material: Premium silicone rubber compound engineered for high temperature and oil resistance.
• Design: Dual‑seal configuration with a reinforced O‑ring profile to maintain consistent pressure against the crankshaft.
• Compatibility: Engineered to fit the crankshaft front seal of numerous models including:
  • Suzuki Vitara Grand (1994–2008)
  • Chevrolet Geo
  • Maruti vehicles
  • Various Suzuki and Chevrolet models with 2.0‑L to 2.5‑L engines.

Material Excellence – Silicone Rubber for Longevity

The core of the Elring 266.340 Seal Ring is a specially formulated silicone rubber that offers exceptional resistance to:

• High Engine Temperatures: Maintains elasticity up to 200 °C, preventing hardening or cracking.
• Oil Exposure: Resistant to degradation from engine oil and additives, ensuring a tight seal over extended periods.
• Mechanical Stress: The reinforced profile absorbs radial pressure without compromising the seal integrity.

Installation Guide – Step‑by‑Step

1. Preparation: Remove the old crankshaft seal by carefully prying it out with a suitable tool. Clean the crankshaft shaft and surrounding area to eliminate debris.
2. Inspection: Verify that the crankshaft bore is free of burrs or damage. Any irregularities should be addressed before proceeding.
3. Seating the Seal: Gently press the new Elring 266.340 into place, ensuring it aligns with the crankshaft flange and sits flush against the oil pan lip.
4. Securing: Use a torque wrench to apply the manufacturer’s recommended torque setting (typically around 10–12 Nm for most applications). This ensures proper compression without over‑tightening.
5. Final Check: Inspect the seal for any gaps or misalignment. A properly seated seal should show no visible oil leakage during a short engine run.

Benefits of Choosing Elring 266.340

• Reliability: Designed to withstand continuous operation in high‑stress environments, reducing the risk of oil leaks and engine damage.
• Ease of Replacement: The standardized dimensions allow for quick swaps with minimal tooling.
• Consistent Performance: Maintains a uniform seal across temperature variations, ensuring optimal engine protection.
• OEM Quality Assurance: Meets or exceeds original equipment specifications, providing confidence in performance and fitment.

Maintenance Tips for Longevity

Even the most robust seals benefit from routine care. Follow these guidelines to extend the life of your Elring 266.340 Seal Ring:

• Regular Inspection: Check for oil leaks or seal wear during scheduled maintenance intervals.
• Avoid Over‑Torque: Excessive tightening can deform the silicone, compromising its sealing ability.
• Use Compatible Oil: Ensure engine oil meets the viscosity and additive specifications recommended by the vehicle manufacturer.
• Keep Surrounding Components Clean: Residual debris or sludge can damage the seal during operation.
