OEX Alternator 12V 150A Bosch Style BXA4041

The OEX Alternator BXA4041 is a new 12V, 150A alternator in Bosch style with a pad mount and internal regulator. It is listed under OEX as a rotating electrical unit and is supplied each, making it suitable for workshop replacement jobs where the key checks are charging output, mounting style, and pulley arrangement.

Important physical details for matching include a 49mm outside diameter pulley with a 6 groove pulley section, a 176mm centre-to-centre mount measurement, and mount leg thickness of 63mm. The pivot hole diameter and adjusting hole diameter are both listed as 8 / 10, so those dimensions need to line up with the vehicle’s bracket and adjustment setup before purchase.

This alternator is marked as suitable for Bosch applications and carries part number BXA4041 with pin code IR148. OEX notes a 3yr passenger and 1yr commercial warranty, which gives a useful ownership reference, but the correct fit still depends on matching the unit’s dimensions, electrical setup, and application details to the vehicle.

The unit weighs 6.88kg and is specified as new rather than remanufactured. For a parts buyer comparing alternators, the most relevant points are the 12V system voltage, 150 amp output, internal regulator, pad mount design, and Bosch-style application.

Application and Buying Notes

Before ordering, compare the part number BXA4041, the Bosch-style unit make, and the mount details against the alternator already fitted to the vehicle. The most useful checks here are the 12V system voltage, 150A output rating, internal regulator, pad mount design, 176mm mount centre-to-centre measurement, and the 49mm 6 groove pulley.

The hole sizes matter just as much as the electrical rating. This alternator is listed with pivot hole diameter and adjusting hole diameter of 8 / 10, plus a 63mm mount leg thickness. If those dimensions do not match the vehicle brackets, belt alignment and installation may be affected even if the alternator family looks similar.

The fitment information supplied covers a range of BMW, Mercedes-Benz, Peugeot, Porsche, Skoda and Volkswagen applications, including BMW 1 and 3 series, Mercedes-Benz A-Class and E-Class, Peugeot 307 and 407, Porsche 911, Skoda Octavia, and Volkswagen Passat. Because multiple model families can share similar-looking alternators, the safest approach is to verify the exact vehicle application against the original unit and the vehicle identification details before fitting.

If you are replacing a charging system component for a commercial vehicle or passenger car, remember that the warranty differs by use: 3 years for passenger use and 1 year for commercial use. The alternator is new and weighs 6.88kg, so it is a substantial component and should be handled and installed with care during comparison and 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 BXA4041 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.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. BXA4041, Brand OEX, Description OEX Alternator 12V 150A Bosch Style, Adjusting Hole Diameter 8 / 10, Pin Code IR148, Power Rating (Amp) 150, Pulley Section 6 Groove, Suits Unit Make Bosch, Alternator Mount Pad.

OEX Alternator 12V 150A Bosch Style. Part number BXA4041 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 Pad. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXA4041, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BMW 1, BMW 1 2004, BMW 1 2005, BMW 1 2006, MERCEDES-BENZ A-CLASS, MERCEDES-BENZ A-CLASS 2004. 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: Confirm compatibility using part number BXA4041, the Bosch-style application, and the listed dimensions and pulley details before purchase. Fitment should always be checked against the vehicle’s original alternator and application data, especially where model ranges and years overlap.
