OEX Alternator 12V 70A Denso Style DXA514

The OEX Alternator DXA514 is a new 12V, 70A unit in Denso style, supplied as a single-leg alternator with internal regulator. Key physical details include a 53mm pulley outside diameter, 5 groove pulley section, 58mm mount leg thickness, 160mm mount centre to centre, and an M8 x 1.25 adjusting hole. These measurements are important when checking whether the alternator will physically suit the vehicle and mounting arrangement.

This alternator is listed for Denso unit applications and carries pin code IR7. If you are matching an existing charging system, the part number DXA514, the 12V electrical system, and the 70A output rating are the most useful identifiers to confirm before ordering. The unit weighs 5.2kg and is supplied new, not remanufactured.

OEX states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with factories that are ISO9001 certified for engineering, testing, and quality control procedures. The alternator is backed by a 3 year passenger / 1 year commercial warranty, which is relevant when comparing it with rebuilt or unverified replacement units.

Application and Buying Notes

When comparing this alternator to the one already in the vehicle, the most important checks are the part number DXA514, the Denso style configuration, and the mounting measurements. The single-leg mount, 58mm mount leg thickness, 10mm pivot hole diameter, and 160mm mount centre to centre all need to line up with the existing bracketry before installation can proceed smoothly.

Electrical output also needs to suit the vehicle’s charging requirements. This unit is rated at 12V and 70A, so it is intended for a 12-volt system where that charging capacity is appropriate. The internal regulator is another key detail, because regulator style must match the vehicle’s charging setup rather than being assumed from appearance alone.

The pulley details are equally important. A 53mm pulley outside diameter with a 5 groove section should be checked against the existing belt arrangement, as pulley size and groove count affect belt alignment and belt compatibility. If the vehicle currently uses a female plug arrangement, the note supplied with this alternator states that HXK-24 and HXK-26 are used for conversion, with an adaptor to suit HXK-26 and HXK-16.

If you are replacing an alternator on a Holden Nova or Toyota Corolla, use the listed application data as a guide only and still compare the old unit against the measurements and connector arrangement. The fitment list points to specific Nova and Corolla applications, but the safest purchase decision is made by matching the part number, mount style, pulley configuration, and plug arrangement together.

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 DXA514 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 70A Denso Style. Part number DXA514 should be checked first. Listed voltage is 12. Listed output rating is 70. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single Leg. Regulator type is Internal. Pulley configuration is 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA514, 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 70 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number DXA514, Denso style, 12V 70A output, single-leg mounting, pulley configuration, and the listed vehicle application details before ordering.
