OEX Alternator 24V 80A Bosch Style BXA9051

The OEX Alternator BXA9051 is a new 24V unit rated at 80A, built in Bosch style and supplied as an each item for rotating electrical applications. It features an internal regulator, twin leg alternator mount, a 17mm shaft diameter and 100mm inside mounting legs, so checking the mounting layout against the existing unit is important before ordering.

This alternator carries OEX part number BXA9051 and is listed with a mount centre to centre measurement of 198mm, an adjusting hole diameter of 11mm and a pivot hole diameter of 13mm. Those dimensions are useful when matching brackets and mounting points on the vehicle or machine already in service.

The unit is supplied new, weighs 7.4kg and is backed by a 3 year passenger / 1 year commercial warranty. A note also states that it may require an additional washer for pulley fitment, so pulley alignment and spacing should be checked during installation.

Suits unit make is listed as Bosch, and the fitment information supplied shows applications across CASE, John Deere, New Holland and Volvo equipment families. Because the fitment list is broad, the safest buying check is to compare the part number, voltage, amperage and physical mounting dimensions before finalising the order.

Application and Buying Notes

Before ordering, compare the replacement unit with the one already fitted. The key checkpoints here are 24V, 80A, Bosch style, internal regulator, twin leg mounting and the BXA9051 part number. If any of those do not line up with the existing alternator or machine specification, the part may not be the correct match.

The physical measurements matter just as much as the electrical rating. This alternator has 100mm inside mounting legs, 198mm mount centre to centre, an 11mm adjusting hole, a 13mm pivot hole and a 17mm shaft diameter. Those details help confirm whether the brackets, adjuster and pulley arrangement will suit the installation.

The note about an additional washer for pulley fitment is worth allowing for during installation. If the pulley spacing or offset differs from the unit being replaced, fitment may need a washer to achieve correct alignment. That is best checked against the old alternator before the vehicle is back in service.

The supplied fitment covers several CASE, John Deere, New Holland and Volvo applications, but those listings still need to be checked against the exact machine build and the existing alternator. Matching by model name alone is not enough if the machine has had previous electrical or bracket changes.

As a new OEX alternator, this unit is intended as a direct replacement where the electrical and mounting details match. It is sold as each, weighs 7.4kg and is backed by a 3 year passenger / 1 year commercial warranty, so it suits buyers who want a new rotating electrical component with defined installation dimensions and warranty coverage.

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 BXA9051 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 BXA9051, 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 24 and output 80 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm compatibility by checking part number BXA9051, the 24V 80A specification, Bosch style mounting details and the physical measurements against the alternator already fitted. The supplied application list should be used as a guide only, not as a guarantee, and the pulley may require an additional washer for correct fitment.
