OEX Alternator 12V 100A Delco Style DXA506

The OEX Alternator DXA506 is a new 12V, 100A unit built in Delco style for vehicles using a Delco alternator application. It is a single-leg mount alternator with an internal regulator, a 5 groove pulley, and a pulley outside diameter of 54mm.

For fitment checks, the key dimensions are the 169mm mount centre to centre, 51mm mount leg thickness, 10mm pivot hole diameter, and M8x1.25 adjusting hole. Those measurements matter just as much as the voltage and amperage rating when confirming replacement suitability.

This alternator is listed as suiting Delco units and carries OEX part number DXA506. It is supplied as a new rotating electrical component and weighs 5.0kg, which can be useful when comparing against the removed unit during identification.

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

Application and Buying Notes

Before buying, compare the removed alternator to the DXA506 dimensions: 169mm mount centre to centre, 51mm mount leg thickness, 10mm pivot hole diameter, and M8x1.25 adjusting hole. These measurements are important because a Delco style alternator can still vary in mounting detail between applications.

The electrical specification is 12V and 100A, so this unit needs to match the vehicle’s charging system requirements. The internal regulator and 5 groove pulley also need to align with the original setup, especially where the belt type and regulator arrangement are not interchangeable without other changes.

If you are replacing an existing Delco unit, compare the pulley outside diameter of 54mm, the single leg mount style, and the pin code IR24 against the old alternator or vehicle parts information. A visual match alone is not enough when mounting points and electrical setup must line up.

For workshop or commercial use, the listed warranty is 1 year, while passenger use is covered for 3 years. Keep your purchase records and confirm the application before fitting, particularly if the vehicle has had prior charging system changes or non-standard repairs.

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 DXA506 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 Delco Style. Part number DXA506 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 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 DXA506, 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.

Compatibility note: Confirm fitment using part number DXA506, the Delco style application, and the measured mounting and pulley details before ordering. Do not rely on appearance alone, as alternator mounting and regulator arrangements can differ between similar vehicles.
