Application and Buying Notes

Before ordering, compare the part number DXA465, the Denso style designation, and the external regulator setup against the alternator already in the vehicle. The listed 12V and 55A output, twin leg mount, 76mm inside mounting legs and 175mm mount centre to centre measurements are all practical checks that help avoid a mismatch.

The pulley details matter as well. This unit is listed with a 4 groove pulley and a 62mm outside diameter, so the belt type and pulley alignment need to match the existing charging system. The pivot hole diameter is 10mm and the adjusting hole is M8x1.25, which should be confirmed against the mounting hardware and bracket.

Fitment references are provided for a range of Daihatsu, Holden, Honda and Toyota applications, but those names alone are not enough to confirm suitability. Matching the alternator shape, regulator type, mounting points and part number is the safest way to check compatibility, especially on vehicles with prior repairs or component changes.

Because this is a remanufactured unit, it is sensible to inspect the vehicle’s charging system condition before installation. A worn belt, damaged wiring, poor earth connection or faulty regulator circuit can affect performance regardless of the alternator rating, so the surrounding components should be checked at the same time.

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 DXA465 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 DXA465 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 4 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA465, 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.

Compatibility note: Confirm fitment by matching the DXA465 part number, Denso style specification, external regulator type, twin leg mount, and the listed mounting and pulley measurements against the vehicle’s existing alternator before purchase.
