OEX Alternator 12V 130A Denso Style DXA4073

The OEX Alternator DXA4073 is a new 12V, 130A alternator designed in a Denso style and supplied with an internal regulator. It is listed with a 7 groove pulley, 53mm pulley outside diameter, and twin leg alternator mount, making the physical mounting details important to confirm before ordering.

This unit uses a mount centre-to-centre measurement of 189mm, an inside mounting legs dimension of 36mm, a pivot hole diameter of M8x1.25 / 11, and an adjusting hole diameter of M10x1.25 / 11. Those measurements are the key checks when matching the alternator to the vehicle application and existing brackets.

As a rotating electrical component, this OEX alternator is supplied new and carries a 3 year passenger / 1 year commercial warranty. The listed part number is DXA4073, with pin code IR115 and a stated suit for Denso units, so the part number and mounting details should be verified carefully against the vehicle before purchase.

Application and Buying Notes

For alternators, the important checks are not just voltage and output. This unit is 12V and rated at 130A, but it also needs to match the Denso style application, twin leg mounting, 189mm centre-to-centre measurement, and the 7 groove pulley arrangement. If any of those details differ from the existing unit, it may not install correctly.

The part number DXA4073, pin code IR115, and the stated suit for Denso units are the strongest identifiers to compare with the old alternator or vehicle information. The pivot hole diameter of M8x1.25 / 11 and the adjusting hole diameter of M10x1.25 / 11 are also useful when checking the bracket and adjustment arm.

Because this is a new alternator rather than a remanufactured unit, it is supplied as a replacement rotating electrical component ready for matching against the vehicle’s charging system requirements. The listed weight is 5.78kg, which can also help when confirming you have the correct unit on hand before workshop time is booked.

If the vehicle is listed in the fitment preview, treat that as a guide rather than a final confirmation. Alternator fitment can vary by engine, charging system, bracket arrangement, and pulley configuration, so the safest approach is to compare the vehicle details, the old unit, and the specifications shown here before purchase.

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 DXA4073 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 DXA4073, 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.

Available application references include TOYOTA FJ CRUISER, TOYOTA FJ CRUISER 2010, TOYOTA LAND CRUISER PRADO, TOYOTA LAND CRUISER PRADO 2009. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm compatibility by matching part number DXA4073, pin code IR115, Denso style application, twin leg mounting, 12V/130A rating, and the listed pulley and bracket measurements against the vehicle before ordering.
