Application and Buying Notes

Before ordering, compare the part number 439783 and the physical details against the unit being removed. The key matching points here are 12V, 180A, 6 groove pulley, clockwise rotation, internal regulator, and the four-point mounting with 128mm mount centre to centre.

The mounting dimensions matter just as much as the electrical rating. Check the 61mm inside mounting legs, M8x1.25 / 9 pivot hole, 49mm pulley outside diameter, and the R 90 position or degree if you are matching a direct replacement rather than adapting parts.

The connector note is important: this unit has no connector for revolution counter. If the original alternator uses a different connector or sensing arrangement, do not assume it will interchange without checking the application and the existing harness connection.

This alternator is new and weighs 7.592kg, so handling and installation should be done carefully. A correct fit is best confirmed by part number, mounting style, pulley configuration and the vehicle application details rather than by appearance alone.

Valeo is identified as both the brand and the unit make, which is useful when matching alternators that are built around a specific OE-style configuration. If the original alternator has the same fitment pattern, electrical rating and connector arrangement, that gives a stronger starting point for compatibility checking.

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 439783 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty One Year, Pin Code IR228, Power Rating (Amp) 180, Pulley Section 6 Groove, Rotation CW, Voltage 12, Mount Cnt to Cnt 128mm, Alternator Charge Current [A] 180.

For part number 439783, 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.

Compatibility note: Confirm fitment using part number 439783, the 12V 180A rating, 6 groove pulley, clockwise rotation, internal regulator, and the four-point mounting dimensions before purchase. Vehicle application details should be checked against the existing alternator and the listed fitment information.
