OEX Alternator 12V 150A Bosch Style BXA085

The OEX Alternator BXA085 is a 12V, 150A unit designed in a Bosch style configuration, with a direct alternator mount and a 5 groove pulley. It is supplied new, weighs 6.78kg, and carries part number BXA085 for identification when matching against the original unit.

Mounting details matter on this alternator. The listed mount centres are 93mm, mount leg thickness is 32mm, the adjusting hole diameter is 10mm, and the mount hole diameter is 9mm. Those dimensions should be checked carefully against the vehicle and the existing alternator before ordering.

This alternator is listed as suitable for Bosch unit applications and is identified with pin code IR169. For buyers replacing a failing charging unit, the key checks are the part number, mounting style, pulley section, and the 12V 150A output rating so the replacement matches the electrical and physical requirements of the vehicle.

Application and Buying Notes

When replacing an alternator, the most important checks are the part number BXA085, the 12V system voltage, and the 150A output. If the replacement unit does not match these details, it may not suit the vehicle’s charging system even if it appears similar externally.

The mounting measurements are just as important as the electrical rating. This unit has 93mm mount centres, 32mm mount leg thickness, a 10mm adjusting hole and a 9mm mount hole, so these figures should be compared with the removed alternator and the vehicle mounting points before fitment.

The 5 groove pulley and 54mm pulley outside diameter need to line up with the belt system already in the vehicle. A mismatch here can affect belt tracking and installation, so it is worth checking the belt arrangement carefully rather than relying on general appearance alone.

This alternator is listed as a Bosch style unit and suits Bosch applications, but Bosch-style parts can still vary by mounting and pulley details. Confirming the vehicle application, the pin code IR169, and the direct mount configuration will reduce the chance of ordering the wrong component.

For workshop or trade use, the new construction and stated warranty of 3 years for passenger applications and 1 year for commercial applications provide a clear purchasing reference. The warranty period depends on how the unit is used, so it is sensible to match the intended vehicle use to the applicable warranty category.

If you are comparing against a worn or missing original alternator, use the physical dimensions, pulley groove count, and part number together. That combination gives a better check than vehicle model alone, especially on charging systems where several similar-looking units may exist.

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 BXA085 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 150A Bosch Style. Part number BXA085 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Direct. Pulley configuration is 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXA085, 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 BXA085, the Bosch style application, the 12V 150A specification, and the mounting and pulley measurements before purchase.
