OEX Alternator 24V 80A Bosch Style BXA040

The OEX Alternator BXA040 is a new 24V, 80A unit built in Bosch style, supplied as an alternator each for rotating electrical applications. It suits Bosch units and uses an internal regulator, so it is important to match the part number and mounting details before ordering.

Key physical dimensions include a 51mm mount leg thickness, 195mm mount centre-to-centre, a 14mm pivot hole diameter, an 8mm adjusting hole diameter, and a 17mm shaft diameter. Those measurements matter because Bosch-style alternators can look similar while still differing in mounting and shaft details.

This alternator weighs 6.6kg and is identified as OEX part number BXA040. OEX notes it sources products from market leading OEMs and aftermarket suppliers, with ISO9001 certified factories supporting testing and quality control procedures.

The unit is covered by a 3yr Passenger 1yr Commercial warranty. For a replacement alternator, the most reliable approach is to compare voltage, amp rating, regulator type, mount style, and shaft dimensions against the original unit already fitted to the vehicle or machine.

Application and Buying Notes

Before buying, compare the 24V system voltage, 80A output, internal regulator, and Bosch-style mounting against the alternator currently fitted. A unit can be close in appearance yet still differ in pivot hole diameter, adjusting hole diameter, shaft diameter, or mount centre-to-centre, which will affect installation.

The mounting details on this alternator are specific: 51mm mount leg thickness, 14mm pivot hole diameter, 8mm adjusting hole diameter, 195mm mount centre-to-centre, and a 17mm shaft diameter. If any of those measurements differ from your original alternator, stop and re-check the application before ordering.

Fitment references point to a number of Hitachi and Volvo applications, including Volvo construction and machine variants. Even so, these references should be used as a guide only, because the safest confirmation is still the part number BXA040 plus a side-by-side check of the regulator type, mount style, and shaft dimensions.

If you are replacing a failed unit, note that this alternator is new rather than remanufactured. That can matter when you are matching the part for a repair, especially where the existing alternator has a Bosch-style case and a single leg mount but the exact dimensions must still line up.

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 BXA040 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 80A Bosch Style. Part number BXA040 should be checked first. Listed voltage is 24. Listed output rating is 80. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single 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 BXA040, 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.

Available application references include HITACHI EH650, HITACHI EH650 2004, VOLVO A, VOLVO A 2011, VOLVO B10, VOLVO B10 2003. 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 compatibility by matching part number BXA040, Bosch-style application details, 24V voltage, 80A output, internal regulator, single leg mount, and the listed mounting measurements against the original alternator before purchase.
