OEX Alternator 12V 85A Delco Style DXA492

The OEX Alternator DXA492 is a new 12V, 85A unit with a Delco style fitment profile and an internal regulator. It is listed as a twin leg alternator mount, with a 57mm inside mounting leg measurement, a 10mm pivot hole diameter, and an M8 x 1.25 adjusting hole.

This alternator uses a 6 groove pulley with a 55mm outside diameter and a 184mm mount centre-to-centre measurement. Those dimensions matter when comparing against the original unit, because alternator mounting points, pulley style, and spacing all need to line up before installation.

OEX identifies this part as Part No. DXA492, with Pin Code IR23 and a weight of 5.7kg. It is supplied as a new rotating electrical component and is backed by a 3yr passenger / 1yr commercial warranty, subject to the supplier’s warranty terms.

Application and Buying Notes

For a correct replacement, compare the existing alternator against the key identifiers on this unit: OEX Part No. DXA492, Delco style, 12V, 85A, and internal regulator. Even where a vehicle is listed in fitment data, the physical details still need to match, including the twin leg mount, 57mm inside mounting legs, 10mm pivot hole, and M8 x 1.25 adjusting hole.

The pulley configuration is also important. This alternator has a 6 groove pulley with a 55mm outside diameter, so it needs to match the belt setup on the vehicle. If the original alternator uses a different pulley section or a different mounting layout, the part may not be suitable even if the vehicle model appears in the fitment list.

The 184mm mount centre-to-centre measurement and 5.7kg weight can help when comparing the new unit with the removed alternator. These measurements are useful when checking bracket spacing and confirming that the replacement is in the same size range as the original unit.

If you are replacing a failed alternator, it is worth checking the charging system layout before fitting the new part. Confirm the regulator type, mounting style, and pulley section, then compare the old unit’s part number where possible. That reduces the risk of ordering a visually similar alternator that does not match the vehicle’s specific application.

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 DXA492 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 85A Delco Style. Part number DXA492 should be checked first. Listed voltage is 12. Listed output rating is 85. 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 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA492, 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 85 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include DAEWOO LEGANZA, DAEWOO LEGANZA 1997, DAEWOO LEGANZA 1998, DAEWOO LEGANZA 1999. 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: Please confirm fitment using the vehicle application, the existing alternator’s part number, and the physical measurements listed for DXA492, including the Delco style twin leg mount, 12V 85A rating, and 6 groove pulley.
