OEX Alternator 12V 100A Delco Style 13SI Pad DXA9133

The OEX DXA9133 is a 12V alternator rated at 100A and built in a Delco style 13SI pad mount layout. It is listed as a new unit with internal regulation, clockwise rotation, and no pulley section applicable, which makes the mounting style and electrical specification important checks before purchase.

Key identification points include part number DXA9133, series 13SI, suit unit make Delco, and alternator mount pad. The unit has a 17mm shaft diameter, 64mm mount centres A, 70mm mount centres B, 160mm mount centre to centre, and 80mm mount leg thickness, so physical fit should be checked against the existing alternator before installation.

This alternator is supplied as each and carries a 12 month warranty. The listed weight is 5.38kg, the adjusting hole diameter is 10.5 / 12.5, and the pin code is IR200. These details are useful when confirming the replacement unit matches the vehicle’s charging system and mounting arrangement.

Application and Buying Notes

Before ordering, compare the existing alternator to the DXA9133 using the part number, 13SI series, Delco style pad mount, and the electrical rating of 12V 100A. A charging system can look similar from the outside while still differing in regulator type, mount spacing, shaft size, or rotation, so these checks matter.

The mount measurements are specific: 64mm mount centres A, 70mm mount centres B, 160mm mount centre to centre, and 80mm mount leg thickness. The shaft diameter is 17mm and the adjusting hole diameter is 10.5 / 12.5, so the brackets and adjusting hardware should be matched carefully to the vehicle’s original arrangement.

This alternator is listed with internal regulation and clockwise rotation. Those details should be confirmed against the vehicle’s charging setup and the removed unit, because the wrong regulator type or rotation can prevent proper installation even when the alternator family appears similar.

The note supplied for this part is 24V version - DXA9134, which helps separate this 12V alternator from the related 24V variant. If the vehicle is not a 12V system, or if the original unit carries different mounting or electrical details, do not rely on appearance alone when selecting the replacement.

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 DXA9133 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.

For part number DXA9133, 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 by matching the part number DXA9133, the 13SI Delco style pad mount layout, and the listed measurements and electrical specifications against the original alternator and vehicle application before purchase.
