OEX Alternator 12V 90A Denso Style DXA516

The OEX Alternator DXA516 is a 12V, 90A unit built in Denso style for applications that use a Denso-type alternator with a twin leg mount. It is a new alternator, not remanufactured, and it carries an internal regulator for installations that match those specifications.

This unit has an M10x1.25 / 11 pivot hole diameter, an M8x1.25 adjusting hole diameter, a 60mm pulley outside diameter, and a 4 groove pulley section. The mount centre to centre measurement is 160mm, with 41mm inside mounting legs and a Twin Leg alternator mount.

The alternator is identified as Part No. DXA516 and uses pin code IR45. The note supplied with the unit states M terminal - Hz output, and an adaptor is required to suit HXK-30, HXK-22, and HXK-17. That makes the part number, mounting dimensions, pulley setup, and connection details the key points to confirm before ordering.

Application and Buying Notes

When matching this alternator, start with the part number DXA516, then check the physical mounting dimensions against the vehicle. The listed measurements include 41mm inside mounting legs, 160mm mount centre to centre, an M10x1.25 / 11 pivot hole diameter, and an M8x1.25 adjusting hole diameter. Those details matter as much as the 12V 90A rating, because a correct electrical rating alone does not confirm the unit will bolt on correctly.

This alternator is described as Denso style and suits a Denso unit make, so it is intended for applications already using that layout. The pulley is a 60mm, 4 groove type, which should be checked against the existing belt setup. If the belt alignment, groove count, or pulley diameter differs from the original unit, the alternator may not be suitable even if the electrical specification appears close.

The note for this part specifies M terminal - Hz output, and an adaptor is required to suit HXK-30, HXK-22, and HXK-17. That is an important compatibility checkpoint if the vehicle wiring or plug arrangement has been changed before, or if the existing connector is not the same as the alternator being replaced. It is also worth checking the 4.9kg weight and the Twin Leg mount style when comparing against the original component.

Warranty coverage is listed as 3yr Passenger 1yr Commercial, which is useful context when selecting the part for private or commercial use. The alternator is new, not remanufactured, and OEX states the product is sourced from market leading Original Equipment Manufacturers and Aftermarket Suppliers with ISO9001 certified factory processes. That does not replace fitment checking, but it does give a clear picture of the product position and the level of manufacturing control stated for the range.

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 DXA516 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 2 ALTERNATORS, Part No. DXA516, Brand OEX, Description OEX Alternator 12V 90A Denso Style, Adjusting Hole Diameter M8x1.25, Pin Code IR45, Power Rating (Amp) 90, Pulley Section 4 Groove, Suits Unit Make Denso.

OEX Alternator 12V 90A Denso Style. Part number DXA516 should be checked first. Listed voltage is 12. Listed output rating is 90. 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 4 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA516, 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 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include TOYOTA DYNA, TOYOTA DYNA 1995, TOYOTA DYNA 1996, TOYOTA DYNA 1997. 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: Confirm fitment by matching Part No. DXA516, the Denso style Twin Leg mounting details, pulley configuration, and the M terminal - Hz output note with the existing vehicle alternator before ordering. Where the vehicle application is listed, it should still be checked against the original unit and connector arrangement.
