OEX Alternator 12V 85A Bosch Style BXA043

The OEX Alternator BXA043 is a new 12V, 85A rotating electrical unit built in Bosch style for Bosch applications. It is a twin leg alternator mount with an internal regulator, 70mm pulley outside diameter, and a 4.94kg unit weight, so it is important to match the physical mounting and drive details before purchase.

Key dimensions include 65mm inside mounting legs, a 187mm mount centre-to-centre measurement, and M10x1.25 pivot and adjusting hole sizing. Those measurements matter when replacing an existing alternator, especially where the engine bracket, pivot bolt, and adjuster arrangement need to line up exactly.

This alternator is listed as new and supplied as each, with OEX identifying it as suitable for Bosch units. The part number is BXA043 and the pin code is IR110, which gives you clear identifiers to check against the unit already fitted to the vehicle or the replacement number supplied by your parts listing.

Application and Buying Notes

When replacing an alternator, match the electrical and mounting details first: this unit is 12V, 85A, with an internal regulator and a twin leg mount. The 65mm inside mounting legs, 187mm centre-to-centre mount spacing, and M10x1.25 pivot and adjuster holes are the practical checks that determine whether the alternator will sit correctly in the bracket and align with the drive system.

The pulley details also need to be checked carefully. This alternator has a 70mm outside diameter pulley with an A section belt profile, so the belt line and pulley width should be compared with the unit being removed. A mismatch here can affect alignment and belt compatibility even when the alternator body appears similar.

Because fitment data is listed across Chevrolet Corvette and a range of Ford applications including Fairlane, Fairmont, Falcon, and LTD, the safest approach is to confirm the exact application against the existing part number BXA043 and the vehicle-specific alternator setup. The product is identified as Bosch style and suited to Bosch units, so matching the make and mounting arrangement is essential before ordering.

OEX lists this alternator as a new unit, and the warranty is 3 years for passenger use and 1 year for commercial use. That warranty period is useful, but it does not replace proper fitment checking. Confirm the part number, regulator type, pulley size, and mounting dimensions against the vehicle and the removed alternator to avoid installation issues.

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 BXA043 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 BXA043 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 A. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXA043, 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.

Available application references include CHEVROLET CORVETTE, CHEVROLET CORVETTE 1970, CHEVROLET CORVETTE 1971, FORD FAIRLANE, FORD FAIRLANE 1984, FORD FAIRLANE 1985. 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: Please confirm compatibility using the part number BXA043, the IR110 pin code, and the listed mounting and pulley dimensions before ordering. Fitment should be checked against the vehicle application and the existing alternator layout, particularly where Bosch style, twin leg mounting, and 12V 85A output are required.
