OEX Alternator 12V 130A Denso Style DXA4066

The OEX DXA4066 is a new 12V alternator rated at 130A and built in a Denso style layout. It uses an internal regulator, a 7 groove pulley, and a twin leg mount, with the unit set up around a 168mm mount centre to centre measurement.

This alternator is listed with pin code IR116 and a pulley outside diameter of 52mm. The adjusting hole diameter is 10mm and the pivot hole diameter is 11 / M10, which are practical reference points when checking the mounting arrangement against the vehicle or removed unit.

OEX backs this alternator with a 3 year passenger / 1 year commercial warranty. The unit is sold as each, weighs 5.78kg, and is identified by part number DXA4066. The listed note also confirms the regulator supplied in this option has an RLO terminal.

Application and Buying Notes

Before ordering, compare the part number DXA4066 and the physical mounting details against the alternator currently fitted to the vehicle. The key checks here are the 12V system, 130A output, twin leg mount, 168mm mount centre to centre measurement, 10mm adjusting hole, and 11 / M10 pivot hole.

The pulley setup also matters. This alternator uses a 7 groove pulley with a 52mm outside diameter, so the belt and pulley arrangement need to match the vehicle application. The unit is described as Denso style and suited to Denso units, which makes the existing alternator style an important reference when confirming the correct replacement.

There is a specific regulator note to check before purchase. The listed option includes a voltage regulator with an RLO terminal. If the vehicle uses a unit with an S terminal, the correct reference is DXA4000. If the vehicle uses a unit with a single LIN terminal, the correct reference is DXA4115. That makes the terminal type on the vehicle a critical confirmation point rather than something to assume.

The supplied fitment data includes Toyota Hiace, Toyota Hiace / Commuter, and Toyota Regius Ace applications, with Hiace / Commuter references across multiple model years from 2005 through 2014 in the grouped preview. Even so, alternator fitment should still be verified by part number, regulator terminal type, and mounting measurements before the vehicle is booked in or the old unit is removed.

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 DXA4066 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. DXA4066, Brand OEX, Description OEX Alternator 12V 130A Denso Style, Adjusting Hole Diameter 10, Pivot Hole Diameter 11 / M10, Pulley Outside Diameter 52mm, Regulator Type Internal, Voltage 12, Alternator Mount Twin Leg.

OEX Alternator 12V 130A Denso Style. Part number DXA4066 should be checked first. Listed voltage is 12. Listed output rating is 130. 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 DXA4066, 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 130 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include TOYOTA HIACE, TOYOTA HIACE / COMMUTER, TOYOTA HIACE / COMMUTER 2005, TOYOTA HIACE / COMMUTER 2006. 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 checking part number DXA4066, the 12V 130A specification, the Denso style layout, the RLO terminal regulator arrangement, and the physical mounting and pulley details against the existing unit before purchase.
