OEX Alternator 12V 50A Denso Style DXA418

This OEX alternator is a new 12V 50A unit in Denso style, identified by part number DXA418. It is designed with an internal regulator, a single leg mount, and a pulley outside diameter of 59mm, so the mounting and drive details need to be checked carefully against the existing unit before ordering.

It suits unit make Denso and carries a pin code of IR17. The alternator has a mount leg thickness of 58mm, pivot hole diameter of 10mm, adjusting hole diameter of M8 x 1.25, and a mount centre to centre measurement of 151mm, all of which are useful reference points when comparing to the original alternator.

The unit is supplied new, weighs 3.6kg, and has pulley section A. A note advises that the original unit pulley may need to be used and that an adaptor to suit HXK-18 may be required, so it is worth confirming the pulley arrangement and mounting interface before purchase.

Application and Buying Notes

Before ordering, compare the part number DXA418, the Denso style listing, and the pin code IR17 with the original alternator on the vehicle. Those identifiers are the most reliable starting point when matching a replacement alternator, especially where the application list includes multiple vehicle makes and years.

The mounting details are important on this unit: single leg mount, 58mm mount leg thickness, 10mm pivot hole diameter, M8 x 1.25 adjusting hole, and 151mm mount centre to centre. Even if the vehicle appears in the application list, these measurements should still be checked against the original alternator to avoid a mismatch at install time.

The pulley details also need attention. This alternator has a 59mm outside diameter pulley and pulley section A, but the note states the original unit pulley may need to be reused. If the existing pulley arrangement differs, confirm whether the adaptor to suit HXK-18 is needed before fitting.

The warranty is listed as 3 years for passenger use and 1 year for commercial use. That warranty detail is useful for purchase planning, but it does not replace the need to verify the physical match, the regulator type, and the connection style against the vehicle’s original charging system setup.

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 DXA418 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.

For part number DXA418, 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 50 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BMW 5, BMW 5 1975, DAIHATSU APPLAUSE, DAIHATSU APPLAUSE 1989, DAIHATSU APPLAUSE 1990, DAIHATSU APPLAUSE 1991. 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 compatibility by matching part number DXA418, pin code IR17, Denso style application details, and all mounting and pulley measurements against the original alternator before ordering.
