OEX Alternator 12V 150A Bosch Style BXA9054

The OEX Alternator BXA9054 is a 12V, 150A unit in Bosch style, supplied as a new alternator for rotating electrical applications. It uses an internal regulator and an 8 groove pulley, with a shaft dimension of 17 and a mount centre-to-centre measurement of 155mm.

This unit is listed with a multi leg alternator mount, 56mm mount leg thickness, 10.5mm pivot hole diameter and 10.5mm adjusting hole diameter. Those dimensions are important when matching the replacement to the existing installation, particularly where bracket spacing and mounting points need to line up exactly.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, and from ISO certified factories. The alternator is backed by a 3 year passenger and 1 year commercial warranty, which gives a clear warranty framework for different duty cycles.

The part number is BXA9054 and the pin code is IR189. If you are replacing an alternator in a Bosch style application, those identifiers are the safest way to check that the unit you are ordering matches the vehicle or equipment already fitted.

Application and Buying Notes

Before ordering, confirm the existing alternator is Bosch style and check the mounting layout against the listed measurements: 155mm mount centre-to-centre, 56mm mount leg thickness, 10.5mm pivot hole diameter and 10.5mm adjusting hole diameter. Those figures are often the quickest way to rule a unit in or out before removal and replacement work starts.

The 12V and 150A rating are the key electrical details to compare with the original unit. If the vehicle or machine is running a different voltage or a different output level, this alternator may not be the correct match even if the physical mounting appears close.

The 8 groove pulley and 56mm pulley outside diameter are also important. Belt type and pulley groove count need to match the application already fitted, otherwise belt alignment and drive compatibility can become an issue.

This is a new alternator with an internal regulator, so it should be checked against the existing charging system setup. Use the part number BXA9054 and the pin code IR189 together with the physical dimensions and Bosch application details to verify the match before purchase.

The listed fitment covers a range of CLAAS, IVECO and JOHN DEERE applications, but those group names are only a guide. Final confirmation should always come from the exact part number, mounting dimensions and the vehicle or equipment already installed.

For commercial or higher-use applications, the warranty terms differ from passenger use, with 3 years for passenger and 1 year for commercial. That makes duty cycle a practical consideration when comparing replacement options.

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 BXA9054 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 BXA9054 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 Multi Leg. Regulator type is Internal. Pulley configuration is 8 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXA9054, 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: Confirm fitment using part number BXA9054, pin code IR189, Bosch style application details and the listed mounting and electrical specifications before ordering. Do not rely on model name alone, as matching alternator fitment depends on the exact unit installed.
