OEX Alternator 12V 70A Bosch Style BXA032

The OEX Alternator BXA032 is a new 12V, 70A unit in Bosch style, supplied as a single-leg alternator with a 5 groove pulley and internal regulator. It is intended for applications that suit Bosch-style alternators and should be checked against the vehicle’s charging system and mounting layout before purchase.

Key physical checks on this unit include a 58mm mount leg thickness, 10mm pivot hole diameter, M8 x 1.25 adjusting hole, and 160mm mount centre-to-centre. The pulley outside diameter is 56mm, and the alternator weighs 9.3kg, so it is worth confirming clearance and bracket match on the vehicle side as well as the electrical connection style.

OEX lists this alternator as new, not remanufactured, and backs it with a 3 year passenger / 1 year commercial warranty. The part number is BXA032 and the pin code is IR110, both of which should be used when cross-checking fitment and replacement suitability against the original unit.

This alternator is grouped under rotating electrical and alternators, and the supplied fitment data includes Holden Apollo and Holden Nova as well as a range of Toyota applications. Because the fitment list spans multiple makes and model series, the safest approach is to confirm the exact application details and the original alternator specifications before ordering.

Application and Buying Notes

Before ordering, confirm the alternator matches the original unit’s Bosch-style layout, single-leg mount and internal regulator arrangement. The key measurements supplied for this unit are 58mm mount leg thickness, 10mm pivot hole diameter, M8 x 1.25 adjusting hole and 160mm mount centre-to-centre, so those dimensions should be compared with the vehicle’s bracket and mounting points.

The 70A output is an important check because charging demand varies by vehicle specification and accessory load. If the original alternator is a different amperage, the part may not be a direct match even if the bolt pattern looks similar, so the original part number, regulator type and pulley configuration should all be verified together.

The 5 groove pulley and 56mm pulley outside diameter are also worth checking, particularly where belt alignment or pulley count matters. A pulley mismatch can create belt noise, poor belt tracking or installation issues, so the existing belt and pulley setup should be matched carefully to the replacement alternator.

Fitment coverage includes Holden Apollo, Holden Nova and a range of Toyota applications, but the listed model names alone are not enough to confirm compatibility. For a correct replacement, compare the vehicle details, original alternator markings, mounting dimensions and electrical connector arrangement against BXA032 and IR110 before fitting.

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 BXA032 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.

For part number BXA032, 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: Please confirm fitment using part number BXA032, pin code IR110, the Bosch-style single-leg mounting arrangement and the supplied dimensions before ordering. Vehicle model names in the fitment data are a guide only, and the exact application should be checked against the original alternator and mounting setup.
