OEX Alternator 12V 130A Denso Style DXA4147

The OEX Alternator 12V 130A Denso Style is a new rotating electrical unit with a 12-volt output, 130 amp power rating, and internal regulator. It is identified by part number DXA4147 and is supplied as each unit, so it suits buyers who need a direct alternator replacement matched by specification rather than by guesswork.

This alternator is listed as Denso style and suits unit make Denso, with a quad leg alternator mount. Key dimensional checks include 36mm inside mounting legs, 175mm mount centre-to-centre, M10x1.25 / 11 pivot hole diameter, 11mm adjusting hole diameter, and a 52.5mm pulley outside diameter. Those measurements are the practical points to confirm before ordering.

The unit weighs 5.8kg and uses a 7 groove pulley section. It is supported by a 3yr Passenger 1yr Commercial warranty, which gives a clear ownership reference for the application the part is intended to serve. If you are replacing an existing alternator, matching the part number DXA4147 and the mounting and pulley details is the safest starting point.

Application and Buying Notes

Before buying, compare the part number DXA4147 with the alternator you are removing or replacing. Matching the part number is the most reliable checkpoint when the application is not fully listed, especially on Denso style units where mounting and pulley details can vary between similar-looking alternators.

The mounting layout matters just as much as the electrical rating. This unit has a quad leg alternator mount, 36mm inside mounting legs, 175mm mount centre-to-centre, and M10x1.25 / 11 pivot hole diameter with an 11mm adjusting hole. If any of those points differ from your current alternator, the unit may not physically line up correctly.

Also confirm the pulley specification before ordering. This alternator uses a 52.5mm pulley with a 7 groove section, so belt alignment and groove count need to suit the vehicle setup. A 12V, 130A alternator with an internal regulator should be compared against the original unit’s output and regulator arrangement to avoid mismatch at installation.

The listed warranty is 3yr Passenger 1yr Commercial, which is useful for ownership context, but it does not replace fitment checking. If the existing alternator has a visible label, part number, or measurable mounting points, use those details to verify compatibility before finalising the order.

OEX notes that its products are sourced from market leading Original Equipment Manufacturers and Aftermarket Suppliers, and from ISO9001 certified factories. Even so, the correct application still depends on the physical and electrical match: voltage, amperage, regulator type, pulley section, and the mounting dimensions listed here.

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 DXA4147 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. DXA4147, Brand OEX, Description OEX Alternator 12V 130A Denso Style, Adjusting Hole Diameter 11, Pin Code IR115, Power Rating (Amp) 130, Pulley Section 7 Groove, Suits Unit Make Denso, Alternator Mount Quad Leg.

OEX Alternator 12V 130A Denso Style. Part number DXA4147 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 Quad 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 DXA4147, 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.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Confirm compatibility by checking part number DXA4147, Denso style application, 12V 130A rating, internal regulator, quad leg mount, and the stated pulley and mounting measurements against the existing alternator before purchase.
