Key Features

• Hydraulic Operation: The lifter utilizes a sealed hydraulic system that ensures smooth valve actuation while minimizing wear on the camshaft and valve train.
• Durable Construction: Made from high‑strength alloy steel, the component resists fatigue and corrosion under extreme operating conditions.
• Precision Fit: The design incorporates a Ø11 mm x 27 mm bore that aligns perfectly with standard camshaft profiles found in many European engines.
• Versatile Compatibility: Suitable for use on both intake and exhaust sides, the lifter can be installed in a variety of engine configurations without modification.
• Low Maintenance: The sealed hydraulic chamber eliminates the need for regular fluid checks or adjustments, reducing service intervals.

Applications

The LUK 420006310 Valve Lifter is engineered to fit a broad spectrum of vehicles. It is commonly used in:

• MERCEDES‑BENZ models ranging from the A‑Class and B‑Class to the E‑Class, C‑Class, and S‑Class.
• NISSAN, OPEL, and PUCH engines that require a reliable hydraulic valve lifter.
• RENAULT powertrains where precise valve timing is critical for performance and emissions compliance.
• Vauxhall vehicles, especially those equipped with the 2.0‑L or 2.5‑L engines that demand high durability.

Installation Overview

Installing the LUK 420006310 involves a straightforward replacement of the existing valve lifter:

1. Remove the Old Lifters: Carefully detach the current hydraulic lifters from the camshaft, ensuring no damage to surrounding components.
2. Clean the Camshaft: Remove any debris or old sealant that may interfere with a proper fit.
3. Insert the New Lifters: Align the Ø11 mm x 27 mm bore with the camshaft and secure it using the supplied retaining mechanism.
4. Verify Alignment: Double‑check that the lifter sits flush against the cam lobe to prevent uneven wear.
5. Test Operation: Run a short engine test to confirm smooth valve lift and absence of abnormal noises.
