OEX Alternator 12V 150A Denso Style DXA4076

The OEX Alternator DXA4076 is a 12V, 150A replacement alternator in Denso style, supplied as a new unit for applications that match the listed mounting and pulley details. It uses an internal regulator, a 7 groove pulley, and a quad leg alternator mount, so the physical unit match matters as much as the electrical rating.

This alternator is listed with a 174mm centre-to-centre mount, 36mm inside mounting legs, an M10x1.25 / 11 pivot hole diameter, and an M8x1.25 / 11 adjusting hole diameter. The pulley outside diameter is 52.5mm, and the unit weighs 5.7kg.

OEX notes this unit as Denso style and advises confirmation by OE number, with a specific reminder that it is a 150A alternator. If the vehicle is intended for the 130A version, the listed alternative is DXA4006 rather than this DXA4076 unit.

Application and Buying Notes

Before ordering, confirm the OE number and compare the physical mount pattern against the vehicle’s existing alternator. The key checks for DXA4076 are the quad leg mount, 174mm mount centre to centre, 36mm inside mounting legs, and the M10x1.25 / 11 pivot hole with M8x1.25 / 11 adjusting hole.

The electrical rating also needs to match the vehicle application. This unit is rated at 150A and OEX specifically notes that the 130A version is DXA4006, so it is worth checking the original amperage before fitting. A mismatch in output rating can lead to the wrong part being supplied even when the alternator looks similar.

Pulley and regulator details should also be checked closely. DXA4076 has a 7 groove pulley, a 52.5mm pulley outside diameter, and an internal regulator, which are all practical identification points when comparing to the removed unit or the vehicle’s required specification.

Because this is listed as a Denso style alternator, the application should be confirmed against the vehicle’s original part details rather than relying on appearance alone. Small differences in mounting layout, pulley section, or amperage can change compatibility even within the same model range.

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 DXA4076 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 Denso Style -Confirm by OE number. Part number DXA4076 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 Quad Leg. Regulator type is Internal. Pulley configuration is 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4076, 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.

Compatibility note: Confirm fitment using the OE number, 150A rating, Denso style application, and the listed mounting and pulley measurements before purchase. If the original unit is 130A, check whether DXA4006 is the correct alternative instead of DXA4076.
