ELRING 759.640 Nuts And Bolts
The ELRING 759.640 Nuts And Bolts is a precision‑engineered cylinder head bolt set designed for high‑performance automotive applications. Crafted from premium alloy steel, each component undergoes rigorous heat treatment and surface finishing to ensure maximum strength, durability, and resistance to thermal cycling.
Key Features
- High‑Grade Material: Made from hardened alloy steel with a surface finish of 0.1 µm, providing excellent wear resistance.
- Exact Torque Specifications: Each bolt is calibrated to the manufacturer’s torque sequence, guaranteeing optimal clamping force and preventing head gasket leaks.
- Corrosion Protection: Coated with a proprietary anti‑rust layer that withstands aggressive engine environments and high humidity conditions.
- Compatibility: Designed to fit the M104, M104.980/981, M104.992/941/996/952, and other related Mercedes‑Benz, SsangYong, Daewoo, Puch, and Pyeonghwa engine families.

Installation Guidelines
Proper installation of the ELRING 759.640 nuts and bolts is critical for engine reliability. Follow these steps:
- Pre‑cleaning: Remove all debris from the cylinder head and bolt holes using a solvent cleaner.
- Torque Sequence: Apply torque in a star pattern, gradually increasing to the specified values (typically ranging from 30 Nm to 70 Nm depending on engine).
- Check Alignment: Ensure each bolt is seated fully and that the head gasket remains undistorted.
- Final Torque: Re‑torque after a short idle period (5–10 minutes) to account for thermal expansion.
Maintenance Tips
- Inspect bolts periodically for signs of wear or corrosion, especially in high‑humidity environments.
- Avoid using excessive torque; over‑tightening can strip threads or crack the cylinder head.
- Store spare bolts in a dry environment to preserve their anti‑rust coating.
