OEX Alternator 12V 80A Denso Style DXA4029

This OEX alternator is a 12V, 80 amp unit with a Denso style fitment profile, identified by part number DXA4029. It is a new alternator, sold individually, and uses a single leg mount with a 4 groove pulley, so it is important to compare the mounting arrangement and pulley details with the unit being replaced before ordering.

Key physical details include a 58 mm mount leg thickness, 160 mm mount centre to centre, a 10.5 mm adjusting hole diameter and a 63 mm pulley outside diameter. The regulator type is internal, which is another useful checkpoint when matching the replacement to the vehicle’s charging system layout.

OEX states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with factories using ISO9001 certified processes to support engineering, testing and quality control procedures. This alternator is backed by a 3 year passenger / 1 year commercial warranty, which gives added confidence when the correct unit is matched to the vehicle application.

Application and Buying Notes

For this alternator, the safest way to confirm fitment is to match DXA4029 against the unit being removed and then check the mounting and pulley details. The listed measurements, including the 58 mm mount leg thickness, 160 mm mount centre to centre, 10.5 mm adjusting hole diameter and 63 mm pulley outside diameter, are the key physical points that should line up.

The 12V, 80A output is another important match point. If the replacement alternator does not match the vehicle’s voltage, charging output requirement or regulator setup, it may not be suitable even if it appears similar externally. This unit uses an internal regulator, so that should be checked as part of the comparison.

Because the fitment preview includes Honda Civic applications, use the vehicle details carefully and verify the exact application against the part number and the original alternator. Do not rely on the shape alone, as Denso style units can still differ in mounting style, pulley configuration and electrical setup between applications.

If you are replacing a worn alternator, it is also worth checking the condition of the drive belt and pulley alignment while the unit is out. A 4 groove pulley needs to match the belt system fitted to the vehicle, and the single leg mount must align correctly to avoid installation issues.

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 DXA4029 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 DXA4029, 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 80 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm compatibility by matching part number DXA4029, the Denso style fitment, 12V 80A rating, single leg mount, 4 groove pulley, internal regulator and the measured mounting dimensions against the original unit before purchase.
