OEX Alternator 12V 80A Denso Style DXA534

The OEX alternator DXA534 is a new 12V, 80A unit made in a Denso style for applications that call for a single-leg alternator mount and an internal regulator. It is supplied as each unit and weighs 4.9kg, which is useful to note when comparing against the original alternator for a direct replacement.

This alternator uses a 5 groove pulley with a 56mm outside diameter, a 58mm mount leg thickness, a 160mm mount centre-to-centre measurement, and an M8 x 1.25 adjusting hole. The pivot hole diameter is 10mm. These are the key dimensions to compare before ordering, especially where the brackets or belt alignment need to match the original unit.

The unit features an oval regulator plug and comes with an adaptor to suit HXK-30, HXK-22 or HXK-17. It is described as a Denso-style alternator with OEX part number DXA534 and pin code IR11. The warranty listed is 3 years for passenger use and 1 year for commercial use.

Application and Buying Notes

Before ordering, compare the alternator against the original unit using the part number DXA534, the Denso-style specification, and the physical measurements: 58mm mount leg thickness, 10mm pivot hole diameter, M8 x 1.25 adjusting hole, 160mm mount centre-to-centre, and a 56mm 5 groove pulley. Those details are the most practical way to confirm it will sit and drive correctly in the vehicle.

The oval regulator plug is an important check point. This unit also includes an adaptor to suit HXK-30, HXK-22 or HXK-17, so it is worth confirming whether the existing connector arrangement matches one of those adaptor options before fitting. Where the original plug or regulator arrangement differs, the alternator may require additional comparison before it is suitable.

This is a 12V, 80A alternator, so it is intended for systems that match that output range rather than as a generic universal replacement. The internal regulator is another detail that needs to align with the vehicle setup. If the vehicle uses a different regulation style, a direct swap should not be assumed without checking the original alternator specification.

The listed warranty is 3 years for passenger use and 1 year for commercial use, which is helpful context when choosing between repair and replacement. As with any rotating electrical part, correct identification matters: confirm the make, mounting style, pulley groove count, connector type and dimensions before committing to the 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 DXA534 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 80A Denso Style. Part number DXA534 should be checked first. Listed voltage is 12. Listed output rating is 80. 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 DXA534, 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.

Available application references include HOLDEN APOLLO, HOLDEN APOLLO 1989, HOLDEN APOLLO 1990, HOLDEN APOLLO 1991, TOYOTA CAMRY, TOYOTA CAMRY 1983. 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.

Compatibility note: Confirm fitment using part number DXA534, the Denso-style application, the oval regulator plug with adaptor requirements, and all mounting and pulley measurements against the original alternator before ordering.
