OEX Alternator 24V 200A Delphi DXA9131

The OEX Alternator DXA9131 is a new 24V, 200A alternator for Delphi applications, supplied as a twin leg unit with an external regulator arrangement. It is listed with an 8 groove pulley, 83mm pulley outside diameter, and 234mm mount centre to centre, so the mounting and drive details need to be checked carefully against the original unit before purchase.

This alternator uses a 152mm inside mounting leg spacing, 14mm adjusting hole diameter, and 14mm pivot hole diameter. The listed note also states it may require the original pulley, and the pulley diameter should be checked against the original unit, with regulator to suit RGX3103.

As a rotating electrical component, the DXA9131 is intended for applications where the original unit is specified as Delphi. The unit weight is 32.1kg, which is useful to know when comparing parts, handling the alternator, or confirming you are looking at the correct heavy-duty 24V assembly.

Application and Buying Notes

Before ordering, confirm the alternator part number DXA9131, the Delphi unit make, and the 24V 200A specification. Those three details are the quickest way to narrow the part down before checking the mounting and pulley measurements on the vehicle.

The mounting points matter here: this unit is a twin leg alternator with 152mm inside mounting legs, 234mm mount centre to centre, and 14mm adjusting and pivot holes. If the original alternator differs in any of those dimensions, it should be treated as a mismatch until proven otherwise.

The pulley details also need attention. This alternator is listed with an 8 groove pulley and an 83mm outside diameter, and the note says it may require the original pulley. If the belt path, groove count, or pulley diameter does not line up with the original unit, the alternator should not be assumed to be a direct swap.

The regulator arrangement is another key checkpoint. The unit is listed with an external regulator type and a regulator to suit RGX3103. If your original setup uses a different regulator arrangement, that needs to be verified before fitting.

At 32.1kg, this is a substantial rotating electrical component. It is worth confirming the vehicle application, mounting pattern, and pulley match before installation so the part can be fitted once, correctly, without avoidable rework.

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 DXA9131 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 Product Group 1 ROTATING ELECTRICAL, Part No. DXA9131, Brand OEX, Description OEX Alternator 24V 200A Delphi, Adjusting Hole Diameter 14, Pivot Hole Diameter 14, Pulley Outside Diameter 83mm, Regulator Type External, Voltage 24, Alternator Mount Twin Leg.

OEX Alternator 24V 200A Delphi. Part number DXA9131 should be checked first. Listed voltage is 24. Listed output rating is 200. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is External. Pulley configuration is 8 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA9131, 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 24 and output 200 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include DAEWOO BUS, DAEWOO BUS 2009, DAEWOO BUS 2010, DAEWOO BUS 2011. 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 by checking part number DXA9131, the Delphi application, 24V system requirement, 200A rating, twin leg mounting dimensions, pulley details, and regulator arrangement against the original alternator before ordering.
