OEX Alternator 12V 105A Denso Style DXA586

The OEX Alternator DXA586 is a 12V, 105A rotating electrical unit in a Denso style configuration. It is a new alternator with an internal regulator and a pad mount layout, so the key checks are the mounting style, pulley arrangement, and the physical dimensions before ordering.

This alternator is listed with a 6 groove pulley, 48mm pulley outside diameter, 44mm inside mounting legs, 135mm mount centre to centre, and 12mm pivot and adjusting hole diameters. Those measurements matter when matching the unit to the vehicle’s bracket, belt, and mount spacing.

OEX identifies this unit for Denso applications and assigns part number DXA586, with pin code IR45. The unit weighs 5.4kg and is supplied as each, which gives a useful reference when comparing against the original alternator or an existing replacement.

Application and Buying Notes

The most important check on this alternator is matching the physical layout, not just the electrical rating. A 12V, 105A alternator can still differ in mounting pattern, pulley style, regulator type and connector arrangement, so the 44mm inside mounting legs, 135mm mount centre to centre, and 12mm pivot and adjusting holes should be compared against the original unit.

The 6 groove pulley and 48mm outside diameter need to suit the belt system already on the vehicle. If the belt profile or pulley count does not match, the alternator may not install correctly even when the rest of the unit appears similar. The listed Denso style and pad mount design are useful identifiers, but they should still be checked against the removed part.

This is a new alternator, not a remanufactured unit, and it carries a 3yr Passenger / 1yr Commercial warranty. Warranty coverage is helpful, but it does not replace the need to confirm the application details, especially if the vehicle has had previous charging system repairs or an engine conversion.

If you are comparing against an existing alternator, check the part number DXA586 and the pin code IR45 first, then compare the mounting dimensions and pulley details. For MINI and MINI MINI applications, the supplied fitment references are a guide only, and the vehicle’s build details should still be matched carefully before purchase.

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 DXA586 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 105A Denso Style. Part number DXA586 should be checked first. Listed voltage is 12. Listed output rating is 105. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA586, 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 105 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm fitment using the part number DXA586, the Denso style pad mount layout, and the listed measurements before ordering. Vehicle fitment should always be checked against the original alternator and application details, especially where MINI or MINI MINI references are involved.
