OEX Alternator 12V 130A Denso Style DXA4006

The OEX DXA4006 is a new 12V alternator rated at 130A and made to suit a Denso-style unit. It is supplied as a quad leg alternator with an internal regulator, 7 groove pulley, and a mount centre-to-centre measurement of 175mm, so the physical layout needs to match the vehicle application before fitment is attempted.

Key dimensions include 36mm inside mounting legs, M10x1.25 pivot hole diameter, M8x1.25 adjusting hole diameter, and 33mm inside width. The pulley outside diameter is 53mm, and the unit weighs 5.74kg. These details matter when replacing an existing alternator because the mounting style and pulley arrangement must align with the original setup.

This alternator is listed with part no. DXA4006 and pin code IR115. The note supplied with the unit states that the regulator plug has an S terminal option, and that DXA597 should be used if an RLO terminal is required. ACX6250 may be required to confirm circuit configuration, and the fitter should confirm the correct amp rating before ordering.

Application and Buying Notes

Before buying, check the part number DXA4006 against the original alternator and confirm the unit is a Denso-style 12V 130A fitment. The mounting setup is specific: quad leg mount, 175mm centre-to-centre, 36mm inside mounting legs, and a 53mm pulley. If any of those measurements differ, the alternator may not match the vehicle.

The regulator connection also needs attention. This unit has an S terminal in the regulator plug, while the note states DXA597 should be used if an RLO terminal is required. ACX6250 may be needed to confirm circuit configuration, so it is sensible to check the plug arrangement and wiring before installation rather than relying on appearance alone.

Amp rating is another important check. This alternator is 130A, and the note specifically says the fitter should confirm the correct amp rating. If the vehicle requires a 150A unit, DXA4076 is the listed alternative. Matching output correctly helps avoid charging-system mismatch and unnecessary repeat work.

For the best result, compare the original unit’s mounting legs, hole sizes, pulley groove count, regulator plug terminal type, and output rating with the details shown here. The warranty is 3yr Passenger and 1yr Commercial, but warranty coverage does not replace the need to verify physical and electrical compatibility before 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 DXA4006 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 130A Denso Style - See Note. Part number DXA4006 should be checked first. Listed voltage is 12. Listed output rating is 130. 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 DXA4006, 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 130 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment using the part number DXA4006, the Denso-style application, the 12V 130A rating, the quad leg mount, and the regulator terminal arrangement before purchase. If the vehicle requires an RLO terminal or a 150A alternator, a different part is noted in the product information.
