OEX Alternator 12V 80A Denso Style DXA565

The OEX Alternator DXA565 is a new 12V, 80A unit built in Denso style for applications that use a Denso alternator and a twin leg mount. Key dimensions include a 56mm pulley outside diameter, 7 groove pulley section, 45mm inside mounting legs, and a 122mm centre-to-centre mount spacing.

This alternator uses an internal regulator and is supplied as a new rotating electrical unit, sold each. It weighs 4.26kg and carries pivot hole sizing of M10x1.25 / 11, with an M8x1.25 adjusting hole diameter. Those dimensions are important when checking the physical fit before ordering.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with ISO9001 certified factory sourcing to support engineering, testing, and quality control procedures. The listed warranty is 3 years for passenger use and 1 year for commercial use, which gives a clear use-case distinction when you are selecting the part.

Application and Buying Notes

Before ordering, compare the part number DXA565 and the physical details of the alternator already fitted to the vehicle. The most useful checks here are the Denso style design, twin leg mount, 12V system voltage, 80A output, and the pulley arrangement with 7 grooves and a 56mm outside diameter.

Mounting dimensions matter just as much as the electrical rating. Confirm the 45mm inside mounting legs, 122mm mount centre-to-centre spacing, M10x1.25 / 11 pivot hole diameter, and M8x1.25 adjusting hole diameter against the existing unit or mounting bracket. If any of these differ, the alternator may not install correctly even if it looks similar at first glance.

This unit is listed for Denso applications, so the safest approach is to match the unit make, pin code IR115, and the vehicle application details before purchase. If the existing alternator is an original Denso-style unit, check the regulator type and pulley section carefully, as those details can affect interchangeability.

The warranty is different for passenger and commercial use, so it is worth identifying how the vehicle is used before ordering. The 3-year passenger warranty and 1-year commercial warranty are clear, but they do not replace the need to confirm fitment, mounting, and belt alignment before installation.

As with any rotating electrical part, correct identification is the key step. The listed weight of 4.26kg, together with the new construction and internal regulator, provides a useful reference when comparing against the removed unit or cross-checking with workshop notes.

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 DXA565 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. DXA565, Brand OEX, Description OEX Alternator 12V 80A Denso Style, Adjusting Hole Diameter M8x1.25, Pin Code IR115, Power Rating (Amp) 80, Pulley Section 7 Groove, Suits Unit Make Denso, Alternator Mount Twin Leg.

OEX Alternator 12V 80A Denso Style. Part number DXA565 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 Twin Leg. Regulator type is Internal. Pulley configuration is 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA565, 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 TOYOTA ALPHARD, TOYOTA ALPHARD / VELLFIRE, TOYOTA ALPHARD / VELLFIRE 2008, TOYOTA ALPHARD / VELLFIRE 2009. 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 fitment by matching part number DXA565, Denso-style application details, and the listed mounting and pulley dimensions against the vehicle before purchase. If the existing alternator does not match these specifications, do not assume interchangeability.
