OEX Alternator 12V 130A Denso Style DXA4081

The OEX Alternator DXA4081 is a new 12V, 130A unit in Denso style, supplied as an alternator each. It is designed for applications that use a Denso alternator mounting arrangement and carries a single leg mount, with a 169mm mount centre to centre measurement.

Key dimensions include a 73mm outside pulley diameter, 60mm mount leg thickness, 10.5mm pivot hole diameter and an M8 adjusting hole. The alternator uses an internal regulator and an AA pulley section, so matching the charging setup and belt profile is an important part of checking suitability.

OEX lists this unit as part of its rotating electrical range, with the brand noting ISO9001 certified factories and a comprehensive warranty. The part number is DXA4081, which is the best reference to use when comparing against the original unit or an existing replacement.

At 7.5kg, this alternator is a substantial electrical component and should be matched carefully to the vehicle’s original specifications. If the vehicle uses a Denso-style alternator and the mounting, pulley and regulator details line up, DXA4081 may be the correct replacement to investigate further.

Application and Buying Notes

When comparing this alternator to the unit already in the vehicle, start with the part number DXA4081 and the Denso-style application. The alternator is 12V with a 130A rating, so it should only be considered where the vehicle’s charging system is designed for that output and the physical mount matches the supplied dimensions.

The mounting details matter here: single leg mount, 169mm mount centre to centre, 60mm mount leg thickness, 10.5mm pivot hole and M8 adjusting hole. If any of these points differ from the existing alternator, the unit may not install correctly even if it appears similar at first glance.

Pulley details also need to line up. This alternator uses a 73mm outside diameter pulley and an AA pulley section. If the belt type, pulley diameter or rib profile does not match the vehicle’s existing setup, the replacement may not be suitable without further checking.

The internal regulator is another important compatibility checkpoint. Some charging systems use different regulator arrangements, so it is worth confirming the original unit’s regulator type before proceeding. The listed weight of 7.5kg can also help when comparing like-for-like against a removed alternator.

Warranty coverage is listed as 3 years for passenger use and 1 year for commercial use. As with any electrical component, correct identification before purchase is the best way to avoid installation issues, unnecessary downtime and repeat removals.

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 DXA4081 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. DXA4081, Brand OEX, Description OEX Alternator 12V 130A Denso Style, Adjusting Hole Diameter M8, Pin Code IR115, Power Rating (Amp) 130, Pulley Section AA, Suits Unit Make Denso, Alternator Mount Single Leg.

OEX Alternator 12V 130A Denso Style. Part number DXA4081 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 Single Leg. Regulator type is Internal. Pulley configuration is AA. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4081, 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 COASTER, TOYOTA COASTER 1996, TOYOTA COASTER 1997, TOYOTA COASTER 1998. 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 number DXA4081, Denso-style application details, single leg mount dimensions, internal regulator type and pulley specification against the vehicle’s original alternator before ordering.
