OEX Alternator 12V 80A Denso Style DXA518

The OEX Alternator DXA518 is a 12V, 80A replacement alternator built in a Denso style layout. It is a new unit with an internal regulator, twin leg alternator mount, and a B section pulley, making the key mounting and drive details easy to compare against the unit being removed.

Important dimensions for checking against the original alternator include 105mm inside mounting legs, 175mm mount centre to centre, 10mm pivot hole diameter, and an M8 x 1.25 adjusting hole. The pulley outside diameter is 82mm and the unit rotates clockwise.

This alternator is listed with OEM number 100213-0510 -PO, part number DXA518, and a note for 50cc vac pump use. That combination of part identifiers and physical measurements is the safest way to confirm whether it matches the application before ordering.

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

Application and Buying Notes

Before ordering, compare the part number DXA518 and OEM number 100213-0510 -PO with the alternator you are replacing. Matching the identifiers is the quickest way to narrow down whether this OEX 12V 80A Denso style unit is the correct option for the vehicle.

Physical fit matters just as much as electrical output. Check the twin leg mount arrangement, 105mm inside mounting legs, 175mm mount centre to centre, 10mm pivot hole, and M8 x 1.25 adjusting hole against the old alternator so the unit sits correctly in the bracket and adjusts as expected.

The 82mm pulley diameter, B section pulley, and clockwise rotation should also be verified against the existing unit. These details affect belt alignment and drive compatibility, so they should be checked before fitting rather than assumed from appearance alone.

The note for 50cc vac pump use is another useful checkpoint. If the original alternator is paired with a vacuum pump arrangement, confirm that this unit matches the same setup and mounting arrangement before purchase.

Warranty coverage is listed as 3 years for passenger use and 1 year for commercial use. That warranty applies to the product as supplied, but correct application still depends on matching the identifiers and dimensions to the vehicle.

If you are comparing alternatives, use the listed voltage, amperage, regulator type, mounting style, pulley section, and rotation together. An alternator can look similar and still be wrong if even one of those details differs from the replacement unit.

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 DXA518 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.

FAQ

How do I confirm this part is the right match for my application?

Match DXA518 against the original unit and compare the key specifications shown for the product, including voltage 12, output rating 80, mount style Twin Leg, and pulley configuration B. Fitment references can support the identification process, but they should not replace a direct part-number check.

What specifications should I compare before ordering?

The key checkpoints are the part number, voltage, amperage or output rating, mounting arrangement, pulley style, connector or terminal layout, and any listed OEM reference. Together, these details help confirm both physical fit and electrical suitability.

Does this listing include verified fitment information?

This item includes fitment information that can be used as an application guide. Final confirmation should still be based on the original component details and the exact application requirements.

Why is part number confirmation important even when the application looks similar?

Vehicles, trucks, tractors, and equipment can use different electrical units within the same model family. Part number confirmation reduces the risk of ordering a unit with the wrong output, mounting pattern, regulator setup, pulley arrangement, or connector style.

What does the listed electrical rating tell me about this unit?

The listing shows a voltage of 12. The listed output rating is 80. The regulator type is Internal. These details help identify whether the unit matches the original system requirements.

Is warranty information listed for this item?

Yes. The listed warranty is 3yr Passenger 1yr Commercial. Warranty should be considered alongside the part-number and application checks before purchase.
