Application and Buying Notes

Before ordering, match the part number DXA4124, the Denso style unit make, and the listed mounting details. The mount centre-to-centre measurement is 148mm, the mount leg thickness is 21mm, and the pivot hole diameter is 10mm, so those dimensions need to align with the vehicle’s existing alternator setup.

Electrical specifications matter just as much as the physical fit. This unit is 24V and 25A, with an internal regulator, so it should only be considered where those electrical requirements are correct for the application. The pulley is 69mm outside diameter with an A section profile, which should also be checked against the existing drive arrangement.

The adjusting hole is M8x1.25 and the pin code is IR74, both of which are useful identifiers when comparing a removed alternator to the replacement. If the old unit is available, compare the mount type, pulley size, and connector details side by side before fitting.

This alternator is a 3.0kg new unit and is backed by a one year warranty. As with any charging component, confirm the application carefully before purchase, because a Denso style alternator can share a general appearance with other units while still differing in mounting or electrical details.

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 DXA4124 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.

For part number DXA4124, 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 compatibility by matching part number DXA4124, the Denso style unit make, 24V/25A rating, internal regulator, and all mounting and pulley measurements against the vehicle application before ordering.
