OEX Alternator 12V 160A Denso Style DXA4086

The OEX Alternator DXA4086 is a new 12V, 160A alternator built in a Denso style layout for rotating electrical applications. It is a pad mount unit with an external regulator, a 6 groove pulley, and a pulley outside diameter of 52mm, so the physical mounting and belt drive details need to match the vehicle before purchase.

This alternator is listed with ER55 pin code requirements and notes for F1 field positive feed from the computer, plus S sense to computer with 2.4K ohms. Those electrical details matter just as much as the mechanical dimensions, especially when replacing a Denso-style unit where plug type and regulator arrangement must align with the vehicle system.

OEX identifies this as part number DXA4086 and it is supplied new, not remanufactured. The warranty listed is 3 years for passenger use and 1 year for commercial use, which gives a clear reference point for the intended application and the way the unit is categorised.

For buyers comparing alternators, this unit’s key checkpoints are 12V voltage, 160A output, 63mm mount leg thickness, 11mm adjusting hole diameter, and the 6 groove pulley configuration. Matching those details to the existing alternator is the safest way to avoid a mismatch at installation.

Application and Buying Notes

Before ordering, compare the part number DXA4086 with the alternator already fitted to the vehicle, along with the mounting style, pulley arrangement, and electrical connection details. This unit is a Denso style alternator with an external regulator, ER55 pin code, and an F1 field positive feed requirement, so a simple voltage match is not enough on its own.

The 12V and 160A rating tell you the operating system and output capacity, but the physical fit still needs to line up. Check the 63mm mount leg thickness, 11mm adjusting hole diameter, 52mm pulley outside diameter, and 6 groove pulley section against the removed unit or workshop records before fitting.

If the vehicle was originally fitted with a Denso-style alternator, the plug and regulator arrangement should still be checked carefully. The note for S sense to computer with 2.4K ohms is a useful compatibility checkpoint, because alternator control and sensing arrangements can differ even when the unit appears similar externally.

This alternator is supplied new and carries a 3 year passenger / 1 year commercial warranty. Warranty terms do not replace fitment verification, so it is still important to confirm the mounting face, pulley profile, and connector layout are correct for the application before the vehicle is returned to service.

For workshop and trade buyers, the safest approach is to treat the part number, mounting dimensions, pulley details, and pin code as the main selection criteria. Those identifiers are more reliable than appearance alone, especially where Denso-style alternators can be similar across several vehicle applications.

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 DXA4086 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.

OEX Alternator 12V 160A Denso Style. Part number DXA4086 should be checked first. Listed voltage is 12. Listed output rating is 160. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is External. 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 DXA4086, 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 160 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm compatibility using part number DXA4086, the Denso style application, ER55 pin code, external regulator setup, and the listed mounting and pulley measurements before purchase.
