OEX Alternator 12V 140A Bosch Style BXA081

The OEX Alternator BXA081 is a new 12V, 140A unit with a Bosch style layout, designed for vehicles that need a pad mount alternator with an internal regulator. It is listed with a 6 groove pulley, pulley outside diameter of 56mm, and a mount leg thickness of 70mm, so matching the physical dimensions is just as important as matching the electrical rating.

This alternator is identified by part number BXA081 and pin code IR228. It weighs 6.7kg and is supplied as a new unit, not remanufactured. For buyers replacing an existing Bosch style alternator, those identifiers and measurements are the practical checkpoints to compare before ordering.

OEX positions this alternator range around quality, reliability and controlled manufacturing, with ISO9001 certified factories supporting engineering, testing and quality control procedures. The listed warranty is 3 years for passenger use and 1 year for commercial use, which gives a clear use-case split when choosing the right replacement for the vehicle.

Because alternators are sensitive to both fitment and electrical specification, it is worth checking the existing unit carefully. The combination of 12V output, 140A charging capacity, Bosch suitment, pad mount configuration and 6 groove pulley should all line up with the original unit or confirmed application before purchase.

Application and Buying Notes

The safest way to buy this alternator is to compare the existing unit against BXA081, IR228, the Bosch style layout and the physical mounting details. The key dimensions listed here are the 70mm mount leg thickness, 9 / 10 pivot hole diameter, 56mm pulley outside diameter and 6 groove pulley section.

Electrical output matters as much as the mounting shape. This alternator is rated at 12V and 140A, so it should only be selected where that charging specification matches the vehicle’s original equipment or a confirmed replacement requirement. A lower or higher output unit is not something to assume will be interchangeable.

The internal regulator is another detail that needs confirmation. Some vehicles use a different regulator arrangement, and alternator replacement often comes down to matching the exact unit type rather than relying on appearance alone. If the original alternator is accessible, check the label, pulley, plug style and mounting points before making the final call.

OEX states that its alternator range is supported by quality control processes and a warranty of 3 years for passenger use or 1 year for commercial use. That said, warranty support does not replace fitment checking. The buyer still needs to confirm that the Bosch style, pad mount and pin code IR228 align with the vehicle.

For workshop or DIY replacement work, the most useful comparison points are part number, pin code, voltage, amperage, pulley section and mount style. These details reduce the chance of receiving a unit that looks similar but differs in a small, critical way that stops it from fitting or operating correctly.

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 BXA081 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 Part No. BXA081, Brand OEX, Description OEX Alternator 12V 140A Bosch Style, Mount Leg Thickness 70mm, Pivot Hole Diameter 9 / 10, Pulley Outside Diameter 56mm, Regulator Type Internal, Voltage 12, New / Reman. New.

OEX Alternator 12V 140A Bosch Style. Part number BXA081 should be checked first. Listed voltage is 12. Listed output rating is 140. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXA081, 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.

Compatibility note: Confirm fitment using part number BXA081, pin code IR228, Bosch style application details and the physical measurements listed above. If the existing alternator does not match the 12V, 140A, pad mount, 6 groove, internal regulator specification, do not assume compatibility.
