OEX Alternator 12V 180A Valeo Style VXA931

The OEX Alternator VXA931 is a new 12V, 180A unit designed in Valeo style and supplied with a twin leg alternator mount. It uses an internal regulator, a 7 groove pulley, and a 55mm pulley outside diameter, so it suits buyers who need the replacement to line up with the original mounting and drive arrangement.

This alternator is listed with an 80mm inside mounting legs dimension, 10mm pivot hole diameter, 11mm adjusting hole diameter, and 186mm mount centre to centre. Those measurements matter when matching the unit to the vehicle, especially where the alternator bracket, pivot point, and adjustment slot need to align correctly.

OEX identifies this part as product group 1 Rotating Electrical and product group 2 Alternators, with part number VXA931 and pin code IR139. The unit weighs 6.92kg and is covered by a 3 year passenger / 1 year commercial warranty, which gives a clear reference point for both installation and use requirements.

The listing also notes suitability for Valeo unit make. As with any alternator replacement, the safest approach is to confirm the part number, mounting style, pulley specification, and electrical output before ordering, rather than relying on appearance alone.

Application and Buying Notes

Before ordering, compare the alternator part number VXA931 with the part on the vehicle or the existing replacement record. The important matching points here are the 12V system, 180A output, internal regulator, twin leg mount, and 7 groove pulley with a 55mm outside diameter.

Mounting measurements should be checked carefully. This unit is listed with 80mm inside mounting legs, a 10mm pivot hole, an 11mm adjusting hole, and 186mm mount centre to centre. If those dimensions do not match the bracket and adjustment points on the vehicle, the alternator may not install correctly even if the general style looks similar.

The fitment information supplied links this part to Valeo unit make and shows FIAT Ducato and IVECO Daily applications. That is useful guidance, but it should still be cross-checked against the vehicle’s exact build details and the removed unit, because alternator housings, pulley arrangements, and mounting points can vary within the same model family.

The warranty is listed as 3 years for passenger use and 1 year for commercial use. That is helpful for understanding the intended use category, but it does not replace the need to verify the electrical output, regulator type, and pulley section before installation.

Weight is another practical check at 6.92kg. It is not a fitment rule by itself, but it can help confirm that the replacement you receive is consistent with the expected assembly before the unit is fitted to the vehicle.

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 VXA931 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 VXA931, 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: Confirm fitment with part number VXA931, the Valeo unit make reference, and the listed mounting and pulley measurements before purchase. Use the vehicle’s original alternator details and mounting points as the final check, especially for FIAT Ducato and IVECO Daily applications.
