OEX Alternator 12V 150A Bosch Style BXA028

The OEX Alternator BXA028 is a new 12V unit rated at 150A, built in a Bosch style with a pad mount and internal regulator. It is supplied as each unit and is identified by pin code IR139, which is useful when checking the electrical connector arrangement before purchase.

This alternator uses a 7 groove pulley with a 58mm outside diameter, and the mount centre to centre measurement is 175mm. The adjusting hole diameter and pivot hole diameter are both 10.5mm, so matching the physical mounting points matters as much as confirming the electrical rating.

OEX lists this alternator as part of its rotating electrical range, with a 3 year passenger and 1 year commercial warranty. The brand states its products are sourced from leading OE manufacturers and aftermarket suppliers, with ISO9001 certified factories supporting engineering, testing and quality control procedures.

Application and Buying Notes

When comparing this alternator with the original unit, check the part number BXA028 first, then confirm the Bosch-style mounting layout, pad mount, and the 175mm mount centre to centre measurement. The 10.5mm adjusting and pivot holes, plus the 7 groove pulley and 58mm pulley outside diameter, need to match the vehicle arrangement for a proper installation.

The 150A output and 12V system rating make this a high-output alternator, but output alone is not enough for a correct fit. The connector identification, pin code IR139, and regulator type should be checked against the existing unit so the electrical connection and charging setup align with the vehicle’s requirements.

If the vehicle is one of the listed applications, confirm the exact year and model details before ordering. The supplied fitment references include Ford Transit, Land Rover Defender and Nissan GT-R entries, but alternator fitment can still vary with engine, wiring and bracket arrangement, so the physical unit on the vehicle remains the safest reference.

Because this is a new OEX alternator rather than a remanufactured unit, it may suit buyers who want a direct replacement with defined mounting and electrical specifications. Even so, a part number match and a careful check of the pulley section, mount type and dimensions are still the best way to avoid delays or returns.

For workshop or fleet use, the warranty coverage is listed as 3 years for passenger applications and 1 year for commercial applications. That does not replace the need to verify suitability, but it does provide a clear warranty structure to consider alongside the 150A output, Bosch style fitment, and the 7 groove drive arrangement.

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 BXA028 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.

OEX Alternator 12V 150A Bosch Style. Part number BXA028 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. Pulley configuration is 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXA028, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm fitment using part number BXA028, pin code IR139, the Bosch-style pad mount, and the listed dimensions before ordering. Always compare the alternator on the vehicle with the original unit, including pulley section, mounting points and regulator type, as application details can vary even within the same model range.
