OEX Alternator 24V 140A Bosch Style BXA9010

The OEX Alternator BXA9010 is a new 24V, 140A unit in Bosch style, built as a twin leg alternator with an internal regulator and insulated return. It suits Bosch applications and uses a 30mm shaft, which are key checks when comparing it against the original unit already fitted to the vehicle or equipment.

This alternator is listed as a long shaft version and has an important mounting note: for short shaft applications, BXA9011 rotatable front end bracket is required. Mounting dimensions supplied for this unit include 180mm inside mounting legs, 208mm centre to centre, and M12 pivot and adjusting holes, so those measurements should be matched before ordering.

The unit is part number BXA9010, Series T1, and carries a 3 year passenger / 1 year commercial warranty. At 14.6kg, it is a substantial rotating electrical component, so confirming the physical layout, shaft dimension, rotation requirement, and mounting arrangement is just as important as checking the voltage and output rating.

Application and Buying Notes

Before ordering, compare the BXA9010 part number, the 24V charging system, and the 140A output rating against the alternator already fitted. The unit is Bosch style and suited to Bosch applications, but the physical mounting measurements still need to line up: 180mm inside mounting legs, 208mm centre to centre, and M12 pivot and adjusting holes.

The shaft detail matters on this unit. It is a long shaft version with a 30mm shaft diameter, and the notes state that short shaft use requires the BXA9011 rotatable front end bracket. That makes the existing alternator’s front end arrangement an important check before purchase, especially where the original unit has a different shaft setup.

Rotation and regulator type are also worth confirming. This alternator is bi-directional and uses an internal regulator, so it should only be selected where those details match the application. The insulated return may also be relevant when comparing terminal arrangement and wiring style on the original unit.

The listed fitment references include BERTRAM 630 and several MAN applications, including MAN 26.402, MAN 26.41#, MAN 26.423, MAN 30.362, MAN 30.402, MAN BUS, MAN HOCL and MAN TGA entries. Use those references as a guide only, then verify the alternator dimensions, shaft style, and part number against the vehicle or equipment before buying.

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 BXA9010 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 24V 140A Bosch Style. Part number BXA9010 should be checked first. Listed voltage is 24. Listed output rating is 140. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXA9010, 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 140 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BERTRAM 630, BERTRAM 630 1980, MAN 26.402, MAN 26.402 1997, MAN 26.402 1998, MAN 26.41#. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching part number BXA9010, the 24V 140A specification, Bosch-style application, 30mm shaft, and the mounting dimensions provided. If the existing unit is a short shaft version, the BXA9011 rotatable front end bracket is required.
