ELRING 894.028 Cylinder Head Gasket Set

The ELRING 894.028 Cylinder Head Gasket Set is a premium sealing solution engineered for the classic Mercedes-Benz and Puch engines of the late 1980s and early 1990s. Designed to restore optimal compression, eliminate coolant leaks, and ensure long‑term reliability, this gasket kit delivers factory‑grade performance in every component.

Key Features

• Exact Fit for 90-95 Mercedes 300SD / 350SD / 350SDL / S350 – The set is calibrated to the precise dimensions of these iconic powerplants, guaranteeing a seamless seal on every mating surface.
• High‑Temperature Resistance – Constructed from advanced composite materials and reinforced with high‑grade metal inserts, the gasket withstands operating temperatures up to 400 °F (204 °C) without deformation or loss of sealing integrity.
• Corrosion‑Resistant Construction – The gasket’s inner layers are treated with anti‑rust compounds that protect against coolant and oil corrosion, extending service life even in harsh environments.
• Complete Kit Packaging – Each set includes all necessary gaskets (head, valve cover, timing cover), sealant, and a detailed installation guide to simplify the rebuild process.
• Precision Machining – Every gasket is CNC‑milled to exact tolerances, ensuring uniform thickness and preventing uneven pressure distribution that could lead to leaks.
• Compatibility with Original Equipment – The design matches OEM specifications for fitment, compression ratios, and sealing surfaces, preserving the engine’s original performance characteristics.

Product Composition

The ELRING 894.028 Cylinder Head Gasket Set comprises several specialized components:

Installation Overview

1. Preparation: Remove the cylinder head and clean all mating surfaces thoroughly. Inspect for cracks or warping; replace any damaged components before proceeding.
2. Apply Sealant: Spread a thin, even layer of the supplied high‑temperature sealant on the gasket’s sealing surface to enhance adhesion.
3. Position Gasket: Carefully place the head gasket onto the engine block, aligning all bolt holes precisely. Repeat for valve cover and timing cover gaskets.
4. Tighten Bolts in Sequence: Use a torque wrench to tighten cylinder head bolts in a cross‑pattern sequence according to the manufacturer’s specifications (typically 80–100 ft‑lb). This ensures even pressure distribution across the gasket.
5. Reassemble Engine: Reinstall all ancillary components—timing chain, valve train, coolant passages—and reconnect electrical connectors.
6. Final Check: After a short test run, inspect for any signs of leakage or abnormal noise. Adjust torque if necessary and re‑check after the engine reaches operating temperature.

Benefits to Vehicle Owners

• Restored Engine Performance – A properly sealed head gasket eliminates compression loss, allowing the engine to operate at its intended power output.
• Reduced Maintenance Costs – By preventing coolant and oil leaks, the kit reduces the frequency of fluid top‑ups and associated repairs.
• Extended Engine Longevity – The gasket’s durable construction protects internal components from contamination and thermal stress.
• Ease of Replacement – The comprehensive kit eliminates the need to source individual gaskets, saving time and reducing the risk of mismatched parts.
• Preservation of Classic Character – Maintaining original sealing specifications preserves the engine’s authentic sound, feel, and performance profile.

Compatibility Summary

The ELRING 894.028 Cylinder Head Gasket Set is specifically engineered for:

• Mercedes-Benz models: 300SD, 350SD, 350SDL, S350 (1990‑1995)
• Puch engines with the same block and head geometry as the aforementioned Mercedes models.

It is not intended for use on modern or non‑compatible engine blocks. Always verify the engine code before installation.

Quality Assurance & Certification

ELRING employs rigorous quality control protocols, including:

• Dimensional inspections using laser measurement systems.
• Pressure testing of sealed assemblies to confirm integrity under simulated operating conditions.
• Material certification for all components, ensuring compliance with automotive industry standards.

Conclusion

The ELRING 894.028 Cylinder Head Gasket Set represents the pinnacle of sealing technology for classic Mercedes-Benz and Puch engines. Its meticulous design, superior materials, and comprehensive packaging make it an indispensable component for any restoration or maintenance project aimed at preserving the legacy performance of these legendary powerplants.
