OEX Alternator 12V 100A Bosch Style BXA016

The OEX Alternator BXA016 is a new 12V unit rated at 100A, built in Bosch style with a Bosch unit make reference. It suits applications that use a single-leg alternator mount, 154mm mount centre to centre, and a 70mm mount leg thickness, so matching the physical mounting points is just as important as matching the electrical output.

This alternator uses an internal regulator, an AA pulley section, and a pulley outside diameter of 63mm. The adjusting hole diameter is 8mm, which gives you another useful check when comparing the unit to the alternator already fitted to the vehicle.

For buyers comparing replacement charging components, the key identifiers here are OEX, part number BXA016, 12V, 100A, and Bosch style. The unit weighs 5.96kg and is supplied as a new alternator rather than a remanufactured unit.

OEX backs this alternator with a 3yr passenger / 1yr commercial warranty. That support is useful, but the correct application still needs to be confirmed by part number, mount style, pulley details, and the vehicle’s original alternator specification.

Application and Buying Notes

The most important checks on this alternator are the 12V system voltage, the 100A output rating, and the mounting arrangement. A single-leg mount, 154mm mount centre to centre, 70mm mount leg thickness, and 8mm adjusting hole diameter need to line up with the existing unit or the vehicle bracket setup before fitting.

Because this is a Bosch style alternator with an internal regulator and AA pulley section, it is best compared directly against the original alternator rather than chosen by appearance alone. The 63mm pulley outside diameter is another point that can affect belt alignment and should be checked carefully against the removed unit.

The listed application references include a broad range of older European vehicles, but the safest buying method is still to confirm the part number BXA016 and match the physical details. Where alternator housings, pulley styles, or regulator arrangements differ, the same vehicle model can use more than one unit.

If the existing alternator is available, compare the mount type, pulley section, pulley diameter, and regulator type before ordering. The unit weight of 5.96kg can also help when checking that the replacement feels consistent with the original component, especially on vehicles with similar-looking Bosch style alternators.

For commercial use, the warranty is 1 year, while passenger use is covered for 3 years. That is a useful purchasing detail, but it does not replace a fitment check. Correct alternator selection still depends on the vehicle application, the part number, and the mounting and pulley measurements listed here.

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 BXA016 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. BXA016, Brand OEX, Description OEX Alternator 12V 100A Bosch Style, Adjusting Hole Diameter 8, Pin Code IR189, Pulley Outside Diameter 63mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 154mm.

OEX Alternator 12V 100A Bosch Style. Part number BXA016 should be checked first. Listed voltage is 12. Listed output rating is 100. 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 AA. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXA016, 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 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

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 fitment by matching part number BXA016, 12V system voltage, 100A output, single-leg mount details, 154mm mount centre to centre, 70mm mount leg thickness, 8mm adjusting hole diameter, internal regulator, and 63mm pulley outside diameter before purchase.
