Nikko Alternator 24V 30A NXA9716

The Nikko Alternator 24V 30A is a new rotating electrical unit supplied as each, with part number NXA9716. It is a 24 volt alternator rated at 30 amps, with an internal regulator and a twin leg mount arrangement for applications that match those dimensions and mounting points.

Key physical details include 71mm inside mounting legs, 171mm mount centre to centre, a 14mm pivot hole, an M10 adjusting hole, a 75mm pulley outside diameter and a 9 groove pulley section. At 6.5kg, it is a substantial unit intended for compatible heavy-duty equipment rather than a universal fit.

This alternator is listed for Nikko unit make applications and is described as built to withstand the harshest environments. The warranty is one year, which gives buyers a clear reference point when matching the unit against the original alternator or service parts requirement.

Because alternators must match both electrical and mounting details, the safest approach is to check the voltage, amp rating, pulley groove count, hole sizes and mount dimensions against the original unit before ordering. The part number NXA9716 is the most reliable identifier for confirmation.

Application and Buying Notes

Before ordering, compare the original alternator against the NXA9716 details: 24V output, 30A rating, internal regulator, twin leg mount, 71mm inside mounting legs and 171mm mount centre to centre. Those measurements are the quickest way to rule in or rule out a match without removing guesswork.

The pulley details matter as much as the electrical rating. This unit uses a 9 groove pulley section with a 75mm outside diameter, so the belt profile and pulley alignment must suit the machine. If the original alternator uses a different groove count, shaft setup or pulley diameter, it should not be assumed to fit.

Mounting holes are another important checkpoint. The adjusting hole is M10 and the pivot hole is 14mm, which must line up with the machine’s brackets and adjustment hardware. Even when the brand and application family are the same, small mounting differences can stop a unit from fitting correctly.

The listed fitment points toward Komatsu equipment, including a number of excavator, grader, dozer, forklift and wheel loader references. That said, equipment can vary within the same model line, so checking the exact model designation and the original part number is still the most reliable way to avoid a mismatch.

If you are replacing a failed alternator, look for the original tag, stamp or casting details before you order. The part number NXA9716, the 24V/30A rating and the 9 groove pulley are the clearest identifiers here, and they should be verified against the machine already in service.

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 NXA9716 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 30A. Part number NXA9716 should be checked first. Listed voltage is 24. Listed output rating is 30. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 9 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number NXA9716, 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: Confirm compatibility by matching the part number NXA9716, the 24V 30A specification, the internal regulator, the twin leg mount arrangement and the listed measurements against the original alternator and machine application before purchase.
