Valeo Alternator 12V 180A New Pad Mount Direct Fastening Part No. 439583

This Valeo alternator is a new 12V unit rated at 180A, supplied under part number 439583. It uses an internal regulator, an 8 groove pulley, and a pad mount with direct fastening, so the main physical and electrical checks are clear before ordering.

The mounting details supplied for this alternator include a 70mm mount leg thickness, 163mm mount centre to centre, 9mm pivot hole diameter, and 9mm adjusting hole diameter. Those measurements matter when matching the alternator to the original installation, especially where the bracket layout and belt alignment need to line up exactly.

The unit is listed as suitable for Valeo applications and carries a one year warranty. At 8.17kg, it is a substantial rotating electrical component, so it is worth confirming the part number, pulley layout, connector arrangement, and mounting measurements against the vehicle before fitment.

Application and Buying Notes

Before ordering, compare the alternator part number 439583 with the unit currently fitted to the vehicle. The mounting layout is specific: pad mount, direct fastening, 70mm mount leg thickness, 163mm mount centre to centre, and 9mm pivot and adjusting holes. If any of those points differ on the existing unit, the alternator may not install correctly.

The electrical rating is 12V and 180A, so it is important to match the charging system specification rather than relying on appearance alone. The internal regulator and the note of no connector for revolution counter are both practical checkpoints when comparing plugs, regulators, and dash or instrument connections on the vehicle.

The pulley is an 8 groove design with a 50mm outside diameter. That needs to align with the belt system already on the vehicle, because a mismatch in groove count or pulley diameter can create belt fitment problems. The alternator is supplied new and weighs 8.17kg, so handling and installation should be done with care.

If the vehicle is one of the listed Mercedes-Benz applications, use the application details only as a guide and still verify the exact original unit. Alternator fitment is often decided by the mounting ears, pulley arrangement, connector style, and output rating rather than the model name alone. A direct physical comparison remains the safest way to confirm compatibility.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number 439583 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

For part number 439583, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm fitment by matching part number 439583, the 12V 180A specification, the 8 groove 50mm pulley, the pad mount direct fastening layout, and the supplied Mercedes-Benz application details before purchase.
