Nikko Alternator 24V 140A NXA9728

The Nikko alternator listed here is a new 24V unit with a 140A power rating, internal regulator, and an 8 groove pulley. It is identified by part number NXA9728 and OEM number 600-825-9420, with the unit supplied as each.

This alternator is described as an OE product and is set up with a twin leg alternator mount. Key mounting and sizing details include 101mm inside mounting legs, 260mm mount centre to centre, a 17mm adjusting hole diameter, and a 13mm pivot hole diameter.

For buyers comparing replacement charging components, the main checks on this unit are 24V system voltage, 140 amp output, 8 groove pulley configuration, and the listed mounting dimensions. The alternator weighs 17kg and has a 30 shaft dimension, so physical match-up matters as much as electrical specification.

Application and Buying Notes

Before ordering, compare the part number NXA9728 and OEM number 600-825-9420 against the existing alternator. Matching the number is the clearest confirmation point when replacing a charging unit, especially where the vehicle application is not listed here.

The electrical specification is just as important as the physical fit. This unit is a 24V alternator with a 140A rating and internal regulator, so it should only be considered where the system voltage and regulator arrangement match the replacement requirement.

Pulley and mounting details need checking carefully. The alternator uses an 8 groove pulley with an 80mm outside diameter, twin leg mounting, 101mm inside mounting legs, 260mm mount centre to centre, 17mm adjusting hole diameter, and 13mm pivot hole diameter. Those figures are what determine whether the unit will line up correctly in the vehicle.

If the old alternator is still available, compare the mount layout, pulley groove count, shaft dimension of 30, and overall weight of 17kg before ordering. These details are useful when confirming the replacement is the same style and physical size as the part being removed.

Because fitment can vary across different vehicle and equipment applications, the safest approach is to confirm the alternator by part number, OEM number, voltage, amperage, regulator type, and mounting measurements before installation. That reduces the chance of ordering a unit that looks similar but does not suit the application.

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 NXA9728 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.
