OEX Alternator 12V 140A Denso Style DXA4141

The OEX Alternator DXA4141 is a new 12V, 140A rotating electrical unit supplied in Denso style configuration. It suits Denso applications and uses a 6 groove pulley, with an external footprint built around a 170mm centre-to-centre mount and a quad leg alternator mount.

Key physical details include an inside mounting legs measurement of 57mm, a pivot hole diameter of M10x1.25 / 11, and an adjusting hole diameter of M10x1.25 / 11. The pulley outside diameter is 55mm, which is important when matching the belt drive arrangement on the vehicle.

This alternator carries OEX part number DXA4141 and pin code IR206. It is listed as a new unit with an internal regulator and a weight of 5.8kg, so it is worth checking the original alternator layout, mounting style, and belt section before ordering.

Application and Buying Notes

Before buying, compare the alternator part number DXA4141, the Denso style body, and the mounting measurements against the unit fitted to the vehicle. The 170mm centre-to-centre mount, 57mm inside mounting legs, and M10x1.25 / 11 pivot and adjusting holes are the most useful checks when confirming physical compatibility.

The pulley details matter as much as the electrical rating. This alternator is a 12V, 140A unit with a 55mm pulley outside diameter and a 6 groove pulley section, so the belt arrangement needs to match the vehicle’s existing drive setup. If the belt section or pulley type differs, the alternator may not be a direct replacement even if the connector style looks similar.

Because this unit uses an internal regulator and is listed as suiting Denso applications, it is best matched by the original alternator specification rather than by appearance alone. The weight is 5.8kg, which can also be a useful cross-check when comparing the replacement to the removed unit, especially where multiple alternator variants were fitted across the same model range.

The listed applications include Hyundai Santa Fe, Hyundai Sonata, and Kia Sportage, but these names are only a guide. Vehicle fitment can vary by engine, build date, charging system, and accessory drive layout, so the safest approach is to verify the part number, mount pattern, pulley section, and electrical connection before placing the order.

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 DXA4141 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 DXA4141, 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.

Compatibility note: Confirm fitment using OEX part number DXA4141, the Denso style designation, and the matching mount and pulley measurements before purchase. Vehicle model names are a guide only, and the final check should always be made against the alternator fitted to the vehicle.
