Nikko Alternator 24V 140A NXA9714

This Nikko alternator is a 24V, 140A unit identified by part number NXA9714. It is listed as a new alternator with an external regulator and a 10 groove pulley, making the key electrical and mounting details easy to check before ordering.

The mounting layout is a twin leg arrangement with 68mm inside mounting legs, a 283mm centre-to-centre mount distance, a 13mm adjusting hole diameter, and a 15mm pivot hole diameter. Those dimensions matter when matching the alternator to the machine’s existing brackets and belt drive setup.

A regulator part number RGX7009 is noted, and the unit carries IR151 pin code identification. The alternator is described as built to withstand harsh environments, with a listed weight of 24kg and a one year warranty.

This listing is for a Nikko-branded alternator in the rotating electrical category, supplied as each. Because alternators must match both the electrical system and the physical mount, it is worth confirming the part number, voltage, pulley section, and mounting measurements against the original unit before purchase.

Application and Buying Notes

For a 24V machine, the alternator voltage must match the electrical system exactly, and this unit is specified at 140A. That current rating is useful when comparing the replacement against the original alternator or the machine’s charging requirements, especially on equipment with higher electrical loads.

The physical mounting details are just as important as the electrical specification. This unit has a twin leg mount, 68mm inside mounting legs, 283mm centre-to-centre measurement, 13mm adjusting holes, 15mm pivot holes, and 25mm mount leg thickness. If any of those measurements differ from the original alternator or bracket arrangement, the unit may not sit correctly.

The pulley details should also be checked carefully. This alternator uses a 10 groove pulley with an 85mm outside diameter. Belt type and pulley groove count need to align with the existing drive system, otherwise belt alignment and belt wear can become an issue.

The listed regulator type is external, and the regulator part number noted is RGX7009. If the machine uses a different regulator arrangement or a different regulator part number, that needs to be confirmed before ordering. The pin code is IR151, which is another useful identification point when comparing against the existing unit.

This alternator is listed as a new Nikko unit and carries a one year warranty. It is also described as built to withstand harsh environments, but that should be read as a general durability statement rather than a substitute for confirming the fitment and electrical requirements on the machine.

The safest buying approach is to match part number NXA9714 first, then compare the voltage, amperage, regulator type, pulley section, mounting layout, and any application references for the machine. If there is any doubt, check the removed alternator, the bracket measurements, and the machine serial or application details before fitting.

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 NXA9714 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.

Nikko Alternator 24V 140A. Part number NXA9714 should be checked first. Listed voltage is 24. Listed output rating is 140. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is External. Pulley configuration is 10 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number NXA9714, 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: Please confirm compatibility using part number NXA9714, the 24V 140A specification, the external regulator arrangement, the 10 groove pulley, and the mounting measurements before ordering.
