OEX Alternator 24V 25A Denso Style DXA4200

The OEX Alternator DXA4200 is a new 24V, 25A alternator in Denso style, supplied as a single-leg unit with an internal regulator. It is listed with a 69mm pulley outside diameter, a 21mm mount leg thickness, a 148mm mount centre-to-centre measurement, and a pivot hole diameter of 10mm.

This unit is identified as part number DXA4200 and carries pin code IR74. It is designed for applications that suit a Denso-type alternator, so matching the unit style and mounting measurements is important before ordering. The adjusting hole diameter is M8x1.25, which is another useful check when comparing against the original unit.

At 3.0kg, this alternator sits within the normal range for a rotating electrical component of this type, but fitment should still be confirmed against the vehicle’s existing alternator and mounting arrangement. OEX lists this product with a one-year warranty, and it is sold as an each unit.

Application and Buying Notes

Before ordering, compare the part number DXA4200 and pin code IR74 with the alternator already fitted to the vehicle. Those identifiers are the most reliable starting point, especially where the application list is not supplied and the alternator needs to match the original mounting and electrical configuration.

The key measurements on this alternator are the 148mm mount centre-to-centre, 21mm mount leg thickness, 10mm pivot hole diameter, and M8x1.25 adjusting hole diameter. These are the dimensions that usually matter when checking whether the alternator will physically mount in the same position as the existing unit.

This alternator is a 24V, 25A unit with an internal regulator, so it should only be considered where those electrical details match the vehicle’s requirements. The 69mm pulley outside diameter and A-section pulley are also worth confirming against the removed alternator, as pulley size and section need to align with the belt setup already on the vehicle.

Because this is a Denso-style alternator, the safest buying approach is to verify the original unit’s brand style, mount arrangement, and terminal or plug details before purchase. Even when a unit is close in appearance, small differences in mounts or pulley specification can affect installation and operation.

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 DXA4200 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 24V 25A Denso Style. Part number DXA4200 should be checked first. Listed voltage is 24. Listed output rating is 25. 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 A. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4200, 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 24 and output 25 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number DXA4200, pin code IR74, Denso-style application details, and the stated mounting and pulley measurements against the existing alternator before ordering.
