    MEYLE ORIGINAL · CHARGING SYSTEM

    Alternator Freewheel Clutch (Overrunning Pulley)

    The Meyle Original alternator freewheel clutch decouples the alternator during engine deceleration to reduce belt vibration, noise and wear. Built to OE specifications, it improves accessory belt stability, protects the tensioner and helps deliver smooth, consistent charging performance.

    Key Features

    • Precision one-way clutch mechanism for controlled overrun
    • OE-matched groove profile, rib count and offset for correct belt tracking
    • Hardened steel body with corrosion-resistant coating
    • Sealed bearing for long service life in harsh environments
    • Each unit function-tested for freewheel/lock behaviour and run-out

    Why Choose Meyle Original

    • OE-level fit and performance for Bosch, Valeo, Denso and other popular alternators
    • Rigorous quality checks for clutch engagement torque and durability
    • Backed by a 2-Year Manufacturer Warranty (authorised supply)

    What’s Included

    • 1× Alternator Freewheel Clutch Pulley (sold individually)
    • Protective cap/cover only if specified for your part number

    Alternator, belt, tensioner and special tools are not included.

    Check Before You Buy

    • Pulley type: Your vehicle may use an OAP (overrunning pulley) or an OAD (decoupler) — match like-for-like
    • Rib count & diameter: e.g., 6PK/7PK, outer diameter and offset
    • Alternator make/model: Bosch, Valeo, Denso, etc.
    • Thread & tool pattern: internal spline/Torx type and thread direction per OE
    • Vehicle details by VIN/registration and OE cross-reference

    When to Replace

    • Belt chirp/squeal on startup or shutdown; harsh belt whip
    • Tensioner arm fluttering or excessive vibration at idle
    • Charging voltage fluctuations or intermittent charging faults
    • Roughness, seized/free-spinning both ways during bench test

    FAQ


    You can enter your Vehicle Registration Number on our homepage or manually select your vehicle details. We will then filter the parts that match your vehicle. Always double-check the Product Properties section to confirm correct fitment.


    Yes! We’re constantly expanding our product range and catalog. If you can’t find the part you’re looking for, please contact us. We work with several manufacturers and may be able to source the part for you.


    Many product pages include a Fitment Details tab with additional information. If you still have questions, feel free to use our message service — we’re happy to help.


    Parts do not come with additional items like fitting kits or gaskets unless it is clearly specified in the Part Details section of the product page.


    Brake Discs: Most standard brake discs are priced individually, but for safety reasons, they must be purchased in pairs. When required, we will automatically set the quantity to 2 in your basket.
    Brake Pads: These are sold as a set (either front or rear), so one box is enough for two discs.


    The Compatibility Table can be found on each product page, usually below the main product description. Look for a tab or heading labeled Compatibility.
