Magneti Marelli Parts & Services expands its Timing Chain Kit range

Magneti Marelli Parts & Services has expanded its engine timing system range with the introduction of new Timing Chain Kit references, complete Super-Kits, and new VVT (Variable Valve Timing) phasers and OCV (Oil Control Valve) valves. This range extension further increases vehicle coverage, supporting a broad portion of the circulating car parc and including major European and Asian manufacturers such as Audi, BMW, Fiat, Mercedes-Benz, Mitsubishi and Toyota.

The kits are designed to provide complete repair solutions and, where applicable, include all the components required for installation, such as fastening elements, gaskets and seals, ensuring fast replacement operations in line with the vehicle manufacturer specifications.

— Broad coverage and complete kits

The Magneti Marelli Parts & Services Timing Kit range has been developed to meet the maintenance requirements of chain-driven engines, a technology increasingly adopted in modern powertrains for its durability, reliability and ability to ensure precise synchronization between the crankshaft and the camshafts.

Magneti Marelli Parts & Services Timing Kits include all major components required for system replacement, including chains, tensioners, guide rails and, where required, installation hardware, gaskets and oil seals. For selected applications, different kit configurations are available, allowing workshops to choose between standard versions and more comprehensive solutions including additional components such as gears and oil pump drive assemblies.

The offer is further enhanced by the availability of highly technological components commonly found in OE systems but often difficult to find within the independent aftermarket, including VVT phasers, OCV valves and other specific timing system components. These parts have been selected on the basis of the technical and quality expertise developed through extensive experience in the automotive original equipment sector. This broader offering enables workshops to source all components required for complete repairs from a single supplier while ensuring compliance with manufacturer specifications.

— New Super-Kits for integrated repairs

The range extension also includes new Super-Kits, developed to support comprehensive maintenance operations on the key components of engine timing systems.

Each Magneti Marelli Parts & Services Super-Kit can combine timing chain or timing belt kits, water pumps, gaskets, and all installation components required for replacement. This approach reflects a recognized maintenance best practice, since the water pump operation is often linked to the same drive components involved in the timing system and replacing both at the same time helps prevent additional repair work shortly afterwards.

Workshops can therefore manage all wear-related timing system components with a single part number, making parts identification easier and reducing procurement times.

The expansion of the Magneti Marelli Parts & Services timing range also covers variable valve timing applications. New references for VVT phasers and OCV valves have been added, completing the offer for components that are essential for  the correct operation of modern variable valve timing systems.

— VVT phasers and OCV valves

In engines equipped with VVT technology, the engine control unit manages the OCV valve, an electro-hydraulic component that regulates and directs oil flow to the VVT phaser. The phaser adjusts the relative position between the camshaft and the crankshaft, advancing or retarding valve timing according to engine speed and load conditions.

The correct operation of each component within the system contributes to the optimization of engine torque and power while helping reduce fuel consumption and emissions. Incorrect valve timing can lead to increased noise, performance loss, higher fuel consumption and engine warning light activation, making component quality essential during maintenance operations.

Components within the Magneti Marelli Parts & Services range are manufactured using dedicated metallurgical processes designed to enhance durability and reliability. These include chain link carbonitriding, Chrovan chromium-vanadium surface treatments and induction hardening of sprocket teeth. All components are produced in facilities certified according to the automotive IATF 16949 quality standard.

The quality of VVT phaser components is verified through dedicated testing procedures, including high-pressure test benches used to evaluate tensioner and phaser performance by measuring pressures and checking valve leakage, clearances and friction levels. Additional inspections employ digital microhardness testers, surface roughness meters, electronic density gauges and 3D optical measuring instruments.

OCV valves and VVT solenoids are also subjected to advanced testing procedures using air-leakage systems, industrial cameras and dedicated equipment for controlled-temperature testing, tensile testing, electrical resistance measurement, coil insulation verification and high-voltage endurance checks.

— Supporting workshops

Magneti Marelli Parts & Services continuously supports workshops in their installation and maintenance activities through dedicated technical documentation accessible via the QR code included inside the product packaging. This allows technicians to quickly access installation instructions and application-specific technical information.

A dedicated timing system catalogue is also available, providing kit compositions, component images, technical data and OE references to simplify parts identification and selection. The Timing Kit catalogue is available in the Online Catalogues section of the website.

The range is also available through the leading aftermarket electronic catalogues, including the TecAlliance TecDoc platform, enabling operators to identify the correct part quickly and accurately.

All kits are supplied in a dedicated packaging designed to provide optimum protection for fragile components. Through this latest expansion, Magneti Marelli Parts & Services further strengthens its timing system offering, providing the aftermarket with comprehensive solutions for the maintenance of the latest-generation engines.
