OEX Alternator 12V 140A Delphi Style DXA604

The OEX Alternator DXA604 is a new 12V unit rated at 140A and supplied in Delphi style form. It is a single-leg alternator with an internal regulator, a 6 groove pulley, and a pulley outside diameter of 55mm, so the physical mounting and belt details are important when checking application suitability.

This alternator is listed with a mount centre-to-centre measurement of 139mm, a mount leg thickness of 51mm, a pivot hole diameter of 10mm, and an adjusting hole diameter of 10mm. Those dimensions matter because alternator fitment is determined by both the electrical output and the mounting layout, not just the voltage rating or the part number alone.

OEX identifies this unit under part number DXA604 and pin code IR193. It is a rotating electrical component sold as each, weighs 6.54kg, and is covered by a 3yr Passenger 1yr Commercial warranty. For buyers matching an existing alternator, the part number, mounting style, pulley configuration, and amperage should all be checked together before ordering.

Application and Buying Notes

Before ordering, match the alternator against the existing unit’s part number DXA604, Delphi style housing, and single-leg mount. The 12V system and 140A output are only part of the check; the 139mm mount centre-to-centre measurement, 51mm mount leg thickness, and 10mm pivot and adjusting holes also need to line up with the vehicle bracketry.

The 6 groove pulley and 55mm pulley outside diameter are important because belt alignment and belt type must suit the vehicle’s drive setup. If the pulley section or diameter differs from the unit already fitted, it may not be a direct swap even when the alternator is otherwise similar.

This alternator is listed as new and has an internal regulator, so it is intended to be compared with the original unit’s regulator arrangement before purchase. The weight is 6.54kg, which can also be useful when comparing a removed alternator to confirm the replacement is the same style and size.

Where vehicle listing data is available, the confirmed applications provided are Holden Colorado and Holden Colorado 7. Even with those application references, the safest approach is to confirm the vehicle details, the alternator part number, and the physical dimensions together, especially if the vehicle has had previous repairs or electrical modifications.

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 DXA604 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. DXA604, Brand OEX, Description OEX Alternator 12V 140A Delphi Style, Adjusting Hole Diameter 10, Pin Code IR193, Power Rating (Amp) 140, Pulley Section 6 Groove, Suits Unit Make Delphi, Alternator Mount Single Leg.

OEX Alternator 12V 140A Delphi Style. Part number DXA604 should be checked first. Listed voltage is 12. Listed output rating is 140. 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 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA604, 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 140 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HOLDEN COLORADO, HOLDEN COLORADO 2012, HOLDEN COLORADO 2013, HOLDEN COLORADO 2014. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching part number DXA604, Delphi style application, 12V 140A rating, mounting dimensions, and pulley specification against the existing alternator and vehicle application details before purchase.
