OEX Alternator 24V 27A Bosch Style BXA9018

The OEX Alternator 24V 27A Bosch Style, part number BXA9018, is a new rotating electrical unit sold each. It is built as a 24-volt, 27-amp alternator with an internal regulator and a single leg mount, so matching the mounting pattern and electrical requirements is essential before ordering.

Key dimensions include a 56mm mount leg thickness, 144mm mount centre-to-centre, 8mm pivot hole diameter, 10mm adjusting hole diameter and a 17mm shaft diameter. At 5.2kg, it is a substantial unit and should be checked carefully against the original alternator’s physical layout and drive arrangement.

This alternator is listed as suiting Bosch applications and carries the OEX brand identification with pin code IR130. For buyers replacing an existing Bosch style unit, the part number BXA9018 and the listed mounting and shaft measurements are the most useful checkpoints when comparing units side by side.

Application and Buying Notes

Before buying, compare the part number BXA9018 with the existing alternator and check the Bosch-style application against the machine already fitted. The listed 24V, 27A specification is important because alternators must match the vehicle or machine’s electrical system and charging requirements.

The mounting details matter just as much as the electrical rating. This unit uses a single leg mount, 56mm mount leg thickness, 144mm centre-to-centre spacing, an 8mm pivot hole and a 10mm adjusting hole. If any of those measurements differ from the original unit, do not assume it will fit without checking the installation.

The 17mm shaft diameter is another critical check point, especially where the pulley, belt alignment or drive-end arrangement needs to match exactly. Because this alternator is listed as new and not remanufactured, it suits buyers looking for a replacement unit with known dimensions and internal regulation rather than a repairable core exchange part.

The fitment list supplied with this alternator includes a range of construction and industrial machines, but the safest approach is always to confirm the exact application, model and year against the current installation. If you are replacing an alternator on a Bosch-style setup, use the part number, mounting style and shaft size together rather than relying on appearance alone.

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 BXA9018 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 BXA9018, 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 24 and output 27 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching the part number BXA9018, the Bosch-style application, the 24V 27A electrical rating and the listed mounting and shaft dimensions before purchase.
