OEX Alternator 12V 55A Bosch Style BXA9056

The OEX Alternator 12V 55A Bosch Style is a new rotating electrical unit with a 12 volt output and a 55 amp power rating. It is identified by part number BXA9056 and uses an internal regulator, which is an important check point when matching the alternator to the vehicle’s charging system.

This unit is listed as a Bosch-style alternator and is suited to Bosch applications. Key mounting details include a 150mm mount centres measurement, single leg alternator mount, 10mm pivot hole diameter, 12mm adjusting hole diameter, and an 80mm mount leg thickness. Those dimensions matter when you are comparing the replacement to the original unit.

The alternator has a 17mm shaft diameter and a pin code of IR165. It weighs 4.64kg and is supplied as an each unit. For buyers who are replacing a worn or failed alternator, matching the part number, voltage, amperage, regulator type, and physical mounting measurements is the safest way to confirm the right unit before ordering.

Application and Buying Notes

Before ordering, compare the part number BXA9056 with the alternator currently fitted to the vehicle or machine. The listed 12V, 55A rating, internal regulator, and Bosch-style application all need to line up with the original unit for a proper match.

Physical mounting is just as important as electrical output. This alternator uses a single leg mount, 150mm mount centres, a 10mm pivot hole, a 12mm adjusting hole, and an 80mm mount leg thickness, so the old alternator should be checked against those measurements where possible.

The shaft diameter is 17mm and the pin code is IR165. If the existing alternator has a different shaft size, connector arrangement, or mounting layout, the part may not suit even if the vehicle make appears similar.

This is a new OEX alternator supplied under a one year warranty. That warranty gives a clear purchasing reference, but it does not replace fitment checking. For best results, confirm the original alternator details, the regulator type, and the application before fitting.

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 BXA9056 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 BXA9056, 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 55 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number BXA9056, Bosch-style application details, 12V 55A output, internal regulator type, and the listed mounting measurements before purchase.
