OEX Alternator 12V 80A Denso Style DXA556

The OEX Alternator DXA556 is a 12V, 80A replacement unit built in a Denso style configuration. It is supplied as a new alternator, with an internal regulator and a 5 groove pulley, and is listed as a single leg mount application.

This unit uses a 57mm mount leg thickness, a 153mm mount centre-to-centre measurement, a 10mm pivot hole diameter, and an 8mm adjusting hole diameter. Those dimensions matter when matching the alternator to the existing bracketry, because the physical mounting points need to line up as well as the electrical output.

OEX lists this alternator as part of its rotating electrical range and identifies the unit as suitable for Denso applications. It carries a 3 year passenger vehicle warranty and 1 year commercial warranty, which is useful for buyers who want a replacement alternator with clear warranty support and a defined electrical specification.

Application and Buying Notes

The main identifiers to confirm on this alternator are DXA556, 12V, 80A, internal regulator, and Denso style. Those details should be matched carefully against the existing unit, because alternators with similar appearance can still differ in mounting geometry or electrical setup. The 5 groove pulley and 69mm outside diameter are also important when comparing to the vehicle’s accessory drive.

Mounting dimensions are just as important as the electrical rating. This alternator is listed with a 57mm mount leg thickness, 153mm mount centre-to-centre, a 10mm pivot hole, and an 8mm adjusting hole. If those figures do not align with the brackets on the vehicle, the alternator may not install correctly even if the part looks close at first glance.

The supplied fitment information points to Honda applications, including Accord, Civic, Odyssey, and Prelude references, but it should still be treated as application guidance rather than a blanket guarantee. A careful parts check should include the vehicle’s exact model, year, mounting style, pulley count, and the existing alternator part number where available. That is the safest way to avoid delays or unnecessary returns.

For buyers comparing options, the fact that this is a new OEX alternator with a 3 year passenger and 1 year commercial warranty may be relevant, especially if the vehicle is used regularly. The 4.94kg weight and single leg mount arrangement can also help when verifying you have the correct replacement unit before installation begins.

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 DXA556 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.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. DXA556, Brand OEX, Description OEX Alternator 12V 80A Denso Style, Adjusting Hole Diameter 8, Pin Code IR2, Power Rating (Amp) 80, Pulley Section 5 Groove, Suits Unit Make Denso, Alternator Mount Single Leg.

OEX Alternator 12V 80A Denso Style. Part number DXA556 should be checked first. Listed voltage is 12. Listed output rating is 80. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single Leg. Regulator type is Internal. Pulley configuration is 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA556, 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.

Available application references include HONDA ACCORD, HONDA ACCORD 1985, HONDA ACCORD 1986, HONDA ACCORD 1987. 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: Please confirm compatibility with the part number DXA556, the Denso style application, and the listed mounting measurements before purchase. Fitment should always be checked against the specific vehicle and existing alternator, especially where Honda application details or pulley and bracket dimensions may vary.
