ELRING 802.790 Nuts And Bolts

ELRING 802.790 Nuts and Bolts for Cylinder Heads

The ELRING 802.790 is a premium bolt kit designed specifically for the cylinder heads of high‑performance vehicles such as BMW, Land Rover, and Morgan models. This comprehensive set includes all necessary fasteners to secure the head to the block with precision, ensuring optimal compression, durability, and engine reliability.

Key Features

• Exact Torque Specifications: Each bolt is engineered to meet the manufacturer’s torque requirements, preventing over‑tightening or under‑tightening that could compromise head gasket integrity.
• High‑Strength Material: Made from hardened alloy steel with a protective coating, these bolts resist corrosion and maintain strength under extreme temperatures.
• Torx Exterior Design: The external Torx heads provide excellent grip for torque wrenches, reducing the risk of stripping and ensuring consistent tightening.
• Complete Set: Includes all required fasteners—bolts, nuts, washers, and a gasket kit—to complete the cylinder head installation.
• Compatibility: Specifically calibrated for BMW E34, E39, E53 (X5), Land Rover Range Rover III 4.4, Morgan Aero 8, and other models that use the 802.790 bolt pattern.

Product Composition

The kit is divided into two main components:

1. Bolts (M10 x 1.5 mm × 110 mm) – These are the primary fasteners that secure the head to the engine block.
2. Nuts and Washers – Designed to match the bolt size, ensuring a uniform clamping force across all mounting points.

All parts are supplied in a sealed container with clear labeling for easy identification during assembly.

Installation Guidelines

1. Preparation: Clean the cylinder head and block surfaces thoroughly. Inspect bolts for any damage or deformation before use.
2. Gasket Placement: Install the gasket kit as per the manufacturer’s instructions, ensuring it sits flush on both the head and block.
3. Tightening Sequence: Follow a crisscross pattern when tightening bolts to distribute pressure evenly. Use a calibrated torque wrench set to the specified values (typically 80–100 Nm for M10 bolts).
4. Final Check: After all bolts are tightened, perform a final torque verification to confirm that each bolt meets the required specification.

Maintenance and Longevity

The ELRING 802.790 kit is engineered for long‑term performance. Regular inspections during routine maintenance can detect any signs of wear or loosening early, preventing potential head gasket failure. The alloy steel construction resists fatigue, making these bolts suitable for engines that operate under high load and temperature conditions.
