OEX Alternator 12V 105A Delco Style CS130D DXA547

The OEX DXA547 is a new 12V alternator rated at 105A, built in a Delco style and listed with a CS130D series. It suits Delco applications and uses an internal regulator, with ECU voltage control noted for the vehicle system. As supplied, it is a pad mount alternator with a 5 groove pulley and a pulley outside diameter of 61mm.

Key mounting details matter with this unit. The inside mounting legs measure 75mm, the mount leg thickness is 43mm, and both the adjusting hole diameter and pivot hole diameter are 10mm. Those dimensions are the main checks to make against the original alternator before ordering, particularly where bracket and pulley alignment need to remain unchanged.

This alternator is sold as OEX part number DXA547 and is supported by a 3 year passenger / 1 year commercial warranty. The unit weight is 5.78kg, and the listing identifies it as a 12V, 105A rotating electrical component for vehicle charging system replacement work.

OEX positions this alternator range as a quality aftermarket option, with ISO9001 certified factories supporting engineering, testing and quality control procedures. For buyers, the practical point is to match the part number, mounting style, pulley section and electrical configuration before fitting.

Application and Buying Notes

For this alternator, the safest buying check is to compare OEX part number DXA547 with the part you are removing, then confirm the mounting and pulley details. The listed inside mounting legs are 75mm, the adjusting hole diameter is 10mm, the pivot hole diameter is 10mm, and the mount leg thickness is 43mm. Those measurements are often what determines whether the unit will physically suit the bracket setup.

The pulley specification also needs attention. This alternator has a 5 groove pulley with a 61mm outside diameter, so the belt style and groove count need to match the vehicle’s existing arrangement. If the belt or pulley layout is different, it is worth stopping and checking the original unit rather than assuming the alternator will interchange.

Electrical setup is just as important as the physical mounting. This unit is 12V, rated at 105A, uses an internal regulator, and notes ECU voltage control. That means the charging system arrangement on the vehicle needs to be considered before purchase, especially where the original alternator uses a different control strategy or connector arrangement.

The pin code is IR128, which is another useful reference when checking application details. Because this is a Delco style alternator and the listing states it suits Delco, matching the original type and specifications is the sensible approach. If you are unsure, compare the old unit side by side with the published measurements and part number before fitting.

This is a new alternator, not a remanufactured unit, and it carries a 3 year passenger / 1 year commercial warranty. That warranty detail is useful, but it does not replace the need to confirm fitment. The correct part is still the one that matches the vehicle’s mounting, belt drive and control requirements.

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 DXA547 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.

Additional published details for cross-checking include Weight 5.78kg, Product Group 1 ROTATING ELECTRICAL, Part No. DXA547, Brand OEX, Description OEX Alternator 12V 105A Delco Style, Adjusting Hole Diameter 10, Mount Leg Thickness 43mm, Pivot Hole Diameter 10, Pulley Outside Diameter 61mm, Regulator Type Internal.

OEX Alternator 12V 105A Delco Style. Part number DXA547 should be checked first. Listed voltage is 12. Listed output rating is 105. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. 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 DXA547, 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 105 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by checking OEX part number DXA547, the Delco style application, the 12V 105A specification, the 5 groove 61mm pulley, and the listed mounting dimensions before ordering or fitting.
