OEX Alternator 12V 100A Denso Style DXA583

The OEX DXA583 alternator is a new 12V unit rated at 100A and built in a Denso style configuration. It uses an internal regulator, twin leg alternator mount, and a 7 groove pulley, with a pulley outside diameter of 55mm.

This unit is supplied with an RLO terminal in the regulator plug. If the vehicle requires a Sense terminal, use DXA582 instead. ACX6250 may also be required to confirm circuit configuration, so it is worth checking the charging system details before ordering.

Key mounting dimensions include 46mm inside mounting legs, a 123mm centre-to-centre mount measurement, an M10x1.25/11 pivot hole diameter, and an M8x1.25 adjusting hole diameter. The alternator weighs 6kg and is sold each.

Application and Buying Notes

The most important compatibility checks for DXA583 are the regulator plug arrangement and the physical mounting dimensions. This alternator has an RLO terminal in the regulator plug, an internal regulator, twin leg mounting, 46mm inside mounting legs, and a 123mm mount centre-to-centre measurement. If the vehicle needs a Sense terminal instead, DXA582 is the relevant option.

Before fitting, compare the original alternator’s pulley and belt setup with this unit’s 7 groove pulley and 55mm outside diameter. Also check the pivot hole diameter of M10x1.25/11 and the adjusting hole diameter of M8x1.25, as these are practical fitment points when matching the existing assembly.

The alternator is a new 12V, 100A Denso style unit and is intended for applications that suit that configuration. The stated warranty is 3 years for passenger use and 1 year for commercial use, so it is still sensible to confirm the vehicle application and charging system details before purchase rather than relying on appearance alone.

If you are replacing an existing alternator, check the part number, plug style, mounting leg spacing, pulley groove count, and whether the vehicle’s circuit needs an RLO or Sense terminal. ACX6250 may be required to confirm the circuit configuration on some vehicles, which can avoid an incorrect order and extra downtime.

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 DXA583 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 100A Denso Style - See Note. Part number DXA583 should be checked first. Listed voltage is 12. Listed output rating is 100. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA583, 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 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include TOYOTA AVENSIS VERSO, TOYOTA AVENSIS VERSO 2001, TOYOTA AVENSIS VERSO 2002, TOYOTA AVENSIS VERSO 2003. 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: Confirm fitment using the part number DXA583, the Denso style application, and the regulator plug requirement before ordering. If the vehicle needs a Sense terminal, select DXA582 instead. When circuit configuration is uncertain, ACX6250 may be required to confirm the correct setup.
