OEX Alternator 12V 70A Bosch Style BXA012

The OEX Alternator BXA012 is a new 12V, 70 amp unit made to Bosch style specifications, with a 6 groove pulley and internal regulator. It is listed as a twin leg alternator mount and suits Bosch applications where the physical mount and pulley arrangement match the vehicle.

Key dimensions include a 60mm inside mounting leg measurement, 145mm mount centre to centre, an M8 x 1.25 / 8.5 pivot hole diameter, and a 10mm adjusting hole diameter. Those measurements matter just as much as the electrical rating when checking replacement alternators.

This alternator is supplied under the OEX brand, with the brand stated as sourced from market leading original equipment manufacturers and aftermarket suppliers. The unit is new, weighs 4.8kg, and carries a 3 year passenger / 1 year commercial warranty.

Application and Buying Notes

Before ordering, compare the part number BXA012 and the Bosch style application with the alternator already fitted to the vehicle. The mount layout, pulley section, hole sizes, and centre-to-centre measurements need to line up, not just the voltage and amp rating.

The 12V, 70A output is suitable only where the original charging system specification matches. If the vehicle uses a different pulley section, regulator type, or mounting arrangement, the alternator may not suit even if it appears similar at a glance.

Physical checks are important on this unit because the listed dimensions are specific: 60mm inside mounting legs, 145mm mount centre to centre, M8 x 1.25 / 8.5 pivot hole diameter, and a 10mm adjusting hole. Confirm those points against the old part before purchase.

The alternator is listed with a 48mm pulley outside diameter and 6 groove pulley section. Matching belt type and pulley configuration is essential, especially when replacing a Bosch style alternator on a vehicle where the original drive setup must be retained.

The warranty is 3 years for passenger use and 1 year for commercial use. That warranty detail is useful, but it does not replace fitment checking. Final responsibility still sits with the buyer or installer to verify the application details against the vehicle and the removed unit.

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 BXA012 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.

Compatibility note: Confirm fitment by comparing the part number BXA012, Bosch style application, and all mount and pulley measurements with the original alternator before purchase. If the vehicle application or dimensions do not match, do not assume compatibility.
