OEX Alternator 12V 55A Denso Style DXA4102

The OEX Alternator 12V 55A Denso Style is a new alternator rated at 55 amps and 12 volts, with an external regulator and a twin leg alternator mount. It is identified by part number DXA4102 and is listed as suitable for Denso unit applications, so matching the mounting and electrical details is important before purchase.

Key dimensions include 98.5mm inside mounting legs, a 10.5mm pivot hole diameter, an M8 adjusting hole diameter, and a 67mm pulley outside diameter. The pulley section is AA, and the unit is supplied as a new replacement rather than remanufactured.

This alternator sits in the OEX rotating electrical range and is backed by a 3 year warranty for passenger use and 1 year for commercial use. For buyers comparing alternatives, the main points to check are the 12V system, 55A output, external regulator arrangement, and the Denso style mounting layout.

Application and Buying Notes

Before ordering, compare the 12V, 55A specification against the electrical system already fitted to the vehicle or machine. This alternator uses an external regulator, so it should only be considered where the existing charging setup is designed for that arrangement. The unit is also identified as Denso style and suited to Denso unit make applications.

Mounting and pulley details matter just as much as output rating. Check the 98.5mm inside mounting legs, 10.5mm pivot hole diameter, M8 adjusting hole diameter, and 67mm pulley outside diameter against the unit being replaced. If any of those measurements differ, the alternator may not install correctly without modification, which is not something to assume.

The part number DXA4102 is the safest reference point for ordering, especially when fitment is being matched across multiple vehicle lines. Where a vehicle model appears in the fitment data, confirm the exact application against the original unit, the mounting style, and the regulator type before committing to purchase. That approach is more reliable than relying on model name alone.

Warranty coverage is listed as 3 years for passenger use and 1 year for commercial use. As with any charging component, correct installation and correct application matching are important. If the vehicle has been modified, converted, or fitted with a different regulator or pulley arrangement, those changes need to be checked carefully before selecting this alternator.

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 DXA4102 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 55A Denso Style. Part number DXA4102 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 AA. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4102, 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 DAIHATSU DELTA, DAIHATSU DELTA 1989, DAIHATSU DELTA 1990, DAIHATSU DELTA 1991, MITSUBISHI FUSO FIGHTER, MITSUBISHI FUSO FIGHTER 1996. 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: Confirm fitment using part number DXA4102, the 12V 55A specification, external regulator type, twin leg mount, and the measured mounting and pulley dimensions before ordering. Do not rely on vehicle model name alone.
