Application and Buying Notes

Before ordering, compare the part number DXA4094 and pin code IR74 against the alternator already fitted to the machine. The supplied fitment list covers a range of machines, but the safest match is always confirmed by the existing unit details, mounting style, and electrical setup.

The important check points on this alternator are the 12V system, 90A output, internal regulator, single leg mount, and the 58mm pulley outside diameter. If any of those differ from the current unit, the alternator may not suit without further verification.

Physical dimensions also need to line up properly, especially the 163mm mount centre-to-centre, 58mm mount leg thickness, 8mm adjusting hole diameter, and 17mm shaft dimension. These measurements are useful when checking brackets, alignment, and pulley position before purchase.

This alternator is described as new and supplied each, with a 12 Months 20000km warranty. Warranty terms are useful, but they do not replace fitment checks, so the model application and the part identification should still be confirmed before fitting.

If you are replacing a Denso alternator, compare the regulator type, mounting arrangement, and pulley size carefully. A correct electrical rating alone is not enough if the mount or pulley specification is different from the original part.

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 DXA4094 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.
