OEX Alternator 12V 95A Delco 11SI Style DXA4201

The OEX Alternator DXA4201 is a 12V, 95A unit built in Delco 11SI style and supplied as a new alternator, not remanufactured. It uses an internal regulator, a single-leg alternator mount, and an 8 groove pulley section, which are key checks when matching the unit to the existing setup.

This alternator carries part number DXA4201, OEM number 19020208, and is listed with mount leg thickness of 51mm, pivot hole diameter of 10mm, adjusting hole diameter of M8x1.25, and mount centre-to-centre of 173mm. Those dimensions matter because alternators that look similar can differ at the mounting points and pulley setup.

OEX identifies this unit as suitable for Delco applications in the 11SI series. It is a 12 volt charging component with a power rating of 95 amps, weighs 5.2kg, and comes with a one year warranty. For any direct replacement, the important checks are the part number, series, voltage, amperage, and physical mounting dimensions.

Application and Buying Notes

Before ordering, match the part number DXA4201 and confirm the alternator is the Delco 11SI style unit your machine uses. The listed 12V, 95A output is important because alternators must suit both the charging system voltage and the required current output, not just the physical shape.

Check the mounting dimensions against the alternator already fitted: single-leg mount, 51mm mount leg thickness, 10mm pivot hole diameter, M8x1.25 adjusting hole, and 173mm centre-to-centre. A unit with the wrong mounting pattern or pulley section may appear close but still not install correctly.

Also confirm the pulley details before purchase. This alternator has a 58mm pulley outside diameter and an 8 groove pulley section. Those two details need to align with the existing belt arrangement, especially where the alternator is part of a matched drive setup.

The unit is new and carries a one year warranty, which gives a clear service period for the replacement, but it does not remove the need to verify fitment. Weight is listed at 5.2kg, and while weight alone does not confirm application, it can help when comparing against an existing part during inspection.

If you are replacing an alternator on a machine already using an OEX, Delco, or 11SI-style setup, use the OEM number 19020208 and the physical measurements together. That combination is the most reliable way to narrow down whether this is the correct unit for the job.

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 DXA4201 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.
