OEX Alternator 12V 85A Bosch Style BXA073

The OEX Alternator BXA073 is a new 12V unit rated at 85A and built in a Bosch style configuration. It uses an internal regulator, twin leg alternator mount, 3 groove pulley, and clockwise rotation, so the physical layout and charging setup can be checked against the original unit before purchase.

Key mounting measurements include 67mm inside mounting legs, 187mm mount centre to centre, an M10x1.25 pivot hole diameter, and an M10x1.25 adjusting hole diameter. The pulley outside diameter is 53mm, which is a useful comparison point when confirming the replacement alternator against the vehicle’s existing fitment.

This alternator is listed under OEX part number BXA073 and pin code IR110. It is supplied as a new rotating electrical component and carries a 3yr passenger / 1yr commercial warranty, giving a clear service classification for owners and workshops alike.

OEX identifies the unit as suitable for Bosch applications, but the final fit must always be confirmed by the part number, mounting style, pulley section, and electrical configuration on the vehicle already fitted.

Application and Buying Notes

Before ordering, compare the existing alternator against BXA073 for the 12V system, 85A output, internal regulator layout, twin leg mount, and 3 groove pulley. These are the main identification points that separate one Bosch style alternator from another.

The mounting dimensions matter as much as the electrical rating. Check the 67mm inside mounting legs, 187mm mount centre to centre, and the M10x1.25 pivot and adjusting hole sizes against the vehicle already fitted, because small differences in bracket spacing or bolt size can prevent installation.

If you are replacing an original Bosch style alternator, confirm the pulley outside diameter of 53mm and the clockwise rotation before purchase. The wrong pulley section or rotation direction can cause belt alignment issues and charging problems even when the unit looks similar.

The unit is supplied new and carries a 3yr passenger / 1yr commercial warranty, which gives a clear service benchmark, but it does not replace fitment checking. Workshops and private buyers should still compare the vehicle’s current alternator, mounting points, and connector arrangement to the listed part number and specifications.

Where vehicle histories are uncertain, the safest approach is to match the part number BXA073, then verify the Bosch style application, physical dimensions, and pulley configuration. That approach reduces the risk of ordering an alternator that is close in appearance but different in fitment.

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 BXA073 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 12V 85A Bosch Style. Part number BXA073 should be checked first. Listed voltage is 12. Listed output rating is 85. 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. Pulley configuration is 3 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXA073, 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 85 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching OEX part number BXA073, the Bosch style application, 12V/85A rating, twin leg mount, 3 groove pulley, clockwise rotation, and the listed mounting dimensions before purchase.
