OEX Alternator 12V 120A Bosch Style BXA002

The OEX Alternator BXA002 is a 12V, 120A unit in Bosch style, supplied as a new alternator with an internal regulator. It is listed with a single leg mount, 173mm mount centre to centre, 51mm mount leg thickness, and a 10mm pivot hole diameter, so mounting dimensions should be checked carefully against the vehicle or machine before purchase.

This alternator suits Bosch applications and uses an M8 x 1.25 adjusting hole, with a 17mm shaft diameter and no pulley section applicable. Those details matter when comparing against the original unit, especially where the existing alternator has to line up with brackets, belt drive arrangement, and connector style on the vehicle.

OEX positions this range around quality and reliability at aftermarket pricing, with ISO9001 certified factories supporting engineering, testing, and quality control procedures. The unit is backed by a 3yr passenger / 1yr commercial warranty, which gives useful coverage depending on how the alternator is used.

At 5.54kg, this is a substantial rotating electrical component rather than a universal fit item. The correct part number is BXA002, and confirming the Bosch style, 12V system voltage, 120A output, and mounting measurements is the safest way to match it to the application.

Application and Buying Notes

Before ordering, compare the BXA002 part number with the alternator already fitted to the machine or vehicle, then check the Bosch style, 12V system, and 120A output. Those are the primary compatibility checkpoints here, along with the single leg mount and the listed 173mm mount centre to centre measurement.

The mounting dimensions are important because alternators can look similar while differing in leg thickness, pivot hole size, or adjuster hole size. For this unit, the key measurements are 51mm mount leg thickness, 10mm pivot hole diameter, and M8 x 1.25 adjusting hole, so a close physical match should be confirmed before fitting.

Because the pulley section is listed as not applicable, it is worth checking how the existing belt drive arrangement is set up on the original unit. The shaft diameter is 17mm, and that should also be compared with the removed alternator to avoid a mismatch at installation time.

The fitment references include several Allis Chalmers, Case, John Deere, New Holland, SAME and TVT155 applications, but the safest approach is still to confirm by part number and dimensions rather than relying on the brand name alone. Variations can exist across model years and equipment setups, even where the same make and model family appears in the list.

If the existing alternator is damaged or missing, use the system voltage, regulator type, shaft diameter, and mounting layout as the main reference points. A 12V unit with an internal regulator will not suit every charging system, so checking the machine’s original configuration remains essential.

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 BXA002 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.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. BXA002, Brand OEX, Description OEX Alternator 12V 120A Bosch Style, Adjusting Hole Diameter M8 x 1.25, Pin Code IR165, Power Rating (Amp) 120, Regulator Type Internal, Suits Unit Make Bosch.

OEX Alternator 12V 120A Bosch Style. Part number BXA002 should be checked first. Listed voltage is 12. Listed output rating is 120. 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. Pulley configuration is Not Applicable. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXA002, 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 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include ALLIS CHALMERS N5, ALLIS CHALMERS N6, ALLIS CHALMERS N7, CASE 590ST, CASE 590ST 2015, CASE 695ST. 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.

Compatibility note: Confirm compatibility using part number BXA002, Bosch style application details, 12V system voltage, 120A output, and the listed mounting measurements before purchase.
