Key dimensional details matter with alternators, and this unit includes 131mm mount centre to centre, 38.5mm inside mounting legs, and an 8.5mm adjusting hole diameter. The pivot hole diameter is listed as M8x1.25 / 9, which is the sort of detail that needs to match the original unit and bracket arrangement before purchase.

This alternator is part number DXA4101, branded OEX, and marked as suitable for Denso unit make. The stated warranty is 3 years for passenger use and 1 year for commercial use, which gives a clear reference point for buyers comparing replacement options.

Application and Buying Notes

Before ordering, compare the part number DXA4101, the Denso style housing, and the mounting details against the alternator you are replacing. The key checks here are the twin leg mount, 131mm mount centre to centre, 38.5mm inside mounting legs, and the M8x1.25 / 9 pivot hole diameter.

The pulley specification is also important. This unit uses a 6 groove pulley with a 60mm outside diameter, so the belt setup needs to match the vehicle’s original configuration. A mismatch at the pulley or mounting points can stop the alternator from fitting correctly even when the electrical rating is suitable.

The 130A output and 12V rating suit applications that call for those exact electrical specifications, but output alone should not be used to confirm fitment. The alternator must also match the regulator type, mounting style, and physical dimensions already fitted to the vehicle.

The stated compatibility detail available here is that the unit suits Denso application styling. If you are replacing an alternator in a Honda Civic or Honda CR-V, check the original unit, bracket layout, connector arrangement, and part number carefully before ordering. The listed fitment preview should be treated as a guide only unless you can confirm the match against the removed part.

The warranty is 3 years for passenger use and 1 year for commercial use, which is useful when comparing options, but warranty coverage does not confirm application fitment. Final confirmation should always be based on the alternator itself, the bracket dimensions, and the vehicle’s original specification.

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 DXA4101 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 130A Denso Style. Part number DXA4101 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 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4101, 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 HONDA CIVIC, HONDA CIVIC 2013, HONDA CIVIC 2014, HONDA CIVIC 2015. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using the part number DXA4101, the Denso style designation, and the listed mounting and pulley measurements before purchase. If the removed alternator does not match the 12V, 130A, twin leg, internal regulator, 6 groove configuration, do not assume it will fit.
