OEX Alternator 12V 55A Denso Style DXA435

The OEX Alternator DXA435 is a 12V, 55A unit in Denso style, supplied new and listed with a twin leg alternator mount. Key physical points for checking against the vehicle are the 171mm mount centre-to-centre measurement, 76mm inside mounting legs, 10mm pivot hole diameter, M8 x 1.25 adjusting hole, and 82mm pulley outside diameter.

This alternator is specified with an external regulator, a B section pulley, a 17mm shaft dimension, and a pin code of ER1. Those details matter when comparing the replacement to the original unit, especially where the charging system layout, pulley profile, or bracket arrangement needs to match the vehicle exactly.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with factory sourcing from ISO9001 certified operations. The unit is backed by a 3 year passenger / 1 year commercial warranty, which gives a clear warranty structure for owners who are matching a Denso-style alternator to the correct application.

Application and Buying Notes

Before ordering, compare the part number DXA435 and the Denso-style configuration against the alternator currently fitted to the vehicle. The important matching points here are the 12V system, 55A output, external regulator, twin leg mount, and the recorded dimensions of 171mm mount centre-to-centre and 76mm inside mounting legs.

Pulley and shaft details should also be checked carefully. This alternator uses an 82mm outside diameter pulley, a B section pulley profile, and a 17mm shaft dimension. If the existing unit differs in pulley section, shaft size, or mounting layout, the alternator may not be a direct swap even if the vehicle family appears similar.

The application data supplied with this listing indicates a wide range of vehicle and equipment names, including some AUDI, DAIHATSU, HOLDEN, JOHN DEERE, KOMATSU, PEUGEOT, THERMO KING, TOYOTA, VOLKSWAGEN, and YANMAR entries. That range should be treated as application guidance only, and the exact match should still be confirmed against the part number, dimensions, regulator type, and mount style before purchase.

The warranty is listed as 3 years for passenger use and 1 year for commercial use. That is useful context, but warranty does not replace fitment checking. For commercial, industrial, or plant applications, the safest approach is to match the alternator by the current unit’s physical features and identifiers rather than by vehicle name alone.

If you are replacing a Denso-style alternator, pay close attention to the pin code ER1 and the mounting pattern. These identifiers are practical checkpoints for avoiding incorrect replacements, particularly where multiple alternator variants can exist within the same model range or equipment family.

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 DXA435 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty 3yr Passenger 1yr Commercial, Inside Mounting Legs 76mm, Pivot Hole Diameter 10, Pulley Outside Diameter 82mm, Regulator Type External, Voltage 12, Mount Cnt to Cnt 171mm, Shaft Dimension 17.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. DXA435, Brand OEX, Description OEX Alternator 12V 55A Denso Style, Adjusting Hole Diameter M8 x 1.25, Pin Code ER1, Power Rating (Amp) 55, Pulley Section B, Suits Unit Make Denso.

OEX Alternator 12V 55A Denso Style. Part number DXA435 should be checked first. Listed voltage is 12. Listed output rating is 55. 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 B. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA435, 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 55 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include AUDI A5, AUDI A5 2020, DAIHATSU CHARADE, DAIHATSU DELTA, DAIHATSU DELTA 1989, DAIHATSU DELTA 1990. 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: Please confirm fitment using part number DXA435, Denso-style application details, regulator type, mount measurements, pulley specification, and the alternator currently fitted to the vehicle or equipment.
