OEX Alternator 12V 140A Bosch Style BXA047

The OEX Alternator BXA047 is a 12V, 140A unit built in Bosch style with a pad mount arrangement. It is a new alternator, not remanufactured, and it uses an internal regulator for applications that call for that configuration.

Key physical details matter with this unit: it has a 56mm pulley outside diameter, a 6 groove pulley section, a 70mm mount leg thickness, and 9.5mm pivot and adjusting holes. Those measurements are the sort of details that need to line up before ordering.

This alternator sits in the rotating electrical category and is listed with a weight of 6.6kg. The unit is identified by Part No. BXA047 and Pin Code IR161, which are the best reference points when matching against the vehicle or the removed original alternator.

Application and Buying Notes

Before buying, compare the removed alternator with BXA047 and check the Bosch style, pad mount design, internal regulator and 12V 140A rating. Those points are the main indicators that the replacement will suit the vehicle’s charging system and mounting arrangement.

The physical dimensions are just as important as the electrical rating. This unit has a 56mm pulley outside diameter, a 6 groove pulley section, 70mm mount leg thickness, and 9.5mm pivot and adjusting holes. If any of those details differ on the original unit, the alternator may not bolt up or line up correctly.

If you are replacing a Bosch unit, use the part number, pin code IR161, and the mounting and pulley details together. Alternators can look similar from the outside but differ in regulator type, pulley configuration, or bracket spacing, so it is worth confirming the original unit carefully before purchase.

The warranty is listed as 3yr Passenger and 1yr Commercial. That gives a useful reference for expected use, but the correct application match still depends on the vehicle setup and the alternator specification. Commercial vehicles and passenger vehicles are covered differently, so keep that in mind when choosing the part.

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 BXA047 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.
