The OEX Alternator DXA519 is a new 12V, 80 amp unit in Denso style with an internal regulator and single leg mount. It is listed as a replacement alternator for vehicles that use a Denso unit, and the key mounting and pulley details are available to help with a proper match before ordering.

Important physical details on this alternator include a 58mm mount leg thickness, 165mm mount centre to centre, an 11mm pivot hole diameter, and an M8 x 1.25 adjusting hole. The pulley outside diameter is 73mm with an AA pulley section, so those dimensions should be checked carefully against the original unit.

This alternator is supplied new, not remanufactured, and is supported by a 3 year passenger / 1 year commercial warranty. The unit weighs 5.5kg and is identified by part number DXA519, which is the best reference point when comparing against the vehicle’s original alternator or any existing replacement documentation.

Application and Buying Notes

Before buying, compare the original alternator against the DXA519 part number and check the physical mounting points. The listed 58mm mount leg thickness, 165mm mount centre to centre, 11mm pivot hole diameter and M8 x 1.25 adjusting hole are all important when confirming that the new unit will bolt up correctly.

The pulley details matter just as much as the electrical rating. This alternator has a 73mm outside diameter pulley with an AA section, and it is described as a Denso style unit with an internal regulator. If the original alternator differs in pulley size, section or regulator arrangement, the replacement may not be suitable even if the vehicle family appears similar.

There is also a specific note that the L terminal does not drive choke, and that an adaptor suits HXK-30, HXK-22 and HXK-17. That makes it sensible to verify the connector arrangement and any adaptor needs before fitting, especially if the existing wiring or charger-control setup has been altered.

The warranty is 3 years for passenger use and 1 year for commercial use, which gives a clear indication of the intended duty profile. As with any rotating electrical part, final confirmation should be made against the vehicle’s original unit, the part number and the mounting and connector details rather than vehicle name 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 DXA519 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 DXA519, 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 80 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment using part number DXA519, the Denso style specification, and the listed mounting, pulley and terminal details before purchase. Vehicle application references are provided, but the final match should be checked against the original alternator on the vehicle.
