OEX Alternator 12V 150A Denso Style DXA587

The OEX Alternator DXA587 is a new 12V, 150A unit built in a Denso style with a pad mount and internal regulator. It is fitted with a 5 groove pulley, a 55mm pulley outside diameter, and a field control unit with a clutch style pulley.

This alternator is listed as suit unit make Denso, with inside mounting legs of 45mm, a 10mm / M10 pivot hole diameter, and a 10mm adjusting hole diameter. The mount centre to centre measurement is 139mm, which is a useful check when comparing against the original unit.

OEX states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, and that production comes from ISO9001 certified factories with engineering, testing and quality control procedures. Warranty cover is listed as 3 years for passenger use and 1 year for commercial use.

Because alternator fitment can vary with pulley style, mount pattern, regulator type, and application, the part number DXA587 and the listed measurements should be checked carefully against the existing unit before ordering.

Application and Buying Notes

Before ordering, compare the part number DXA587 with the alternator already fitted to the vehicle, then check the mount style, pulley arrangement, and regulator type. This unit is a 12V, 150A alternator with an internal regulator and a pad mount, so those details need to line up with the vehicle’s charging system and bracket arrangement.

The pulley specification matters just as much as the electrical rating. This alternator uses a 5 groove pulley with a 55mm outside diameter and is noted as having a clutch style pulley. If the original unit differs in groove count, pulley diameter, or pulley style, the part may not match correctly even if the vehicle family appears similar.

The physical measurements are worth checking with a vernier or against the removed unit. Key dimensions provided are 45mm inside mounting legs, 10mm / M10 pivot hole diameter, 10mm adjusting hole diameter, and 139mm mount centre to centre. Those measurements help confirm whether the alternator will sit correctly in the bracket and align with the belt path.

This alternator is listed for Denso-style applications and the supplied fitment references include Ford Focus and several Volvo models. Even so, vehicle build dates and engine combinations can change the alternator used, so the safest approach is to match the original unit details rather than relying on the vehicle badge 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 DXA587 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 DXA587, 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 FORD FOCUS, FORD FOCUS 2006, FORD FOCUS 2007, FORD FOCUS 2008, VOLVO C30, VOLVO C30 2006. 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: Please confirm compatibility using part number DXA587, the Denso-style application, the 12V 150A rating, and the listed mounting and pulley measurements before ordering. If the original alternator differs in mount pattern, pulley section, or regulator type, fitment should be rechecked.
