Application and Buying Notes

When comparing this alternator, start with the part number DXA474C and the Denso style specification. The electrical rating is 12V at 40A, so it is intended for systems that match that output and charging setup rather than a higher-output or different-voltage application.

The mounting details are just as important as the electrical rating. This unit has a single leg mount, 24mm mount leg thickness, 10mm pivot hole diameter, 138mm mount centre to centre, and an M8x1.25 adjusting hole, so the physical bracket arrangement needs to line up before purchase.

Pulley and shaft dimensions also need attention. The pulley outside diameter is 69mm with an A section pulley, and the shaft dimension is listed as 15. If the belt profile, pulley size, or shaft arrangement differs from the original unit, the alternator may not suit the application even if the vehicle or machine family looks similar.

For machines and industrial applications, confirm the exact model designation and any build variation before ordering. The listed fitment references cover several ALLIGHT, CASE, KUBOTA and TOYOTA INDUSTRIAL applications, but matching the model name alone is not enough unless the mounting and electrical details also line up.

This alternator is new and carries a 3 year passenger / 1 year commercial warranty. That warranty covers the product type as supplied, but it does not replace the need to verify the part number, regulator type, pulley section and mount dimensions against the original unit.

If you are replacing a Denso style alternator, it is best to compare the old unit directly where possible. Check the tag, terminal arrangement, mount style and all measured dimensions, because the wrong alternator can physically bolt in differently even when the application family is close.

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 DXA474C 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 40A Denso Style. Part number DXA474C should be checked first. Listed voltage is 12. Listed output rating is 40. 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 DXA474C, 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.

Compatibility note: Always confirm fitment using part number DXA474C, the Denso style application, and the listed mounting and electrical dimensions before ordering. Vehicle and machine model names should be checked against the original alternator, bracket layout and pulley details to avoid ordering errors.
