OEX Alternator 24V 140A Bosch Style BXA9020

The OEX Alternator 24V 140A Bosch Style, part number BXA9020, is a new rotating electrical unit with an internal regulator and a 140 amp power rating. It is listed as a Bosch suit unit with a twin leg alternator mount, which makes the mounting arrangement and regulator type important checkpoints before ordering.

This alternator is supplied as each, weighs 15kg, and runs on 24 volts. Those details matter when you are matching a replacement for a heavy vehicle, commercial machine, or bus application where the charging system must align with the vehicle’s electrical setup and physical mounting points.

OEX lists this unit as sourced from market leading original equipment manufacturers and aftermarket suppliers, with production from ISO certified factories. The alternator is backed by a 3yr passenger / 1yr commercial warranty, so it is worth confirming both the part number BXA9020 and the application details before fitting.

Application and Buying Notes

The key buying checks on this alternator are the 24V system, 140A output, twin leg mounting, and Bosch suit unit specification. If any of those points differ from your existing alternator or charging system, the part may not be the correct replacement even if the vehicle family appears similar.

Because the unit is listed as new and fitted with an internal regulator, it is best to compare the part number BXA9020 against the existing alternator and confirm the regulator arrangement before ordering. This is especially important on commercial and heavy vehicle applications where the physical mount and electrical specification must match exactly.

The verified application list includes JOHN DEERE 770D, several MAN variants, MERCEDES-BENZ O 30# and related models, SCANIA K - SERIES and T - SERIES, TAMROCK TORO 0011, and VOLVO B12 and B13 applications. Use those listings as a guide only, and check the full vehicle details where possible rather than relying on model name alone.

The 15kg weight and twin leg mount are useful practical checks when you are comparing the replacement unit in hand. If the old alternator has a different mounting style, a different voltage, or a different amperage rating, it is safer to pause and verify the fit before purchase or installation.

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 BXA9020 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.
