Nikko Alternator 24V 50A New NXA9710

The Nikko alternator listed here is a new 24V, 50A unit with part number NXA9710. It is a twin leg mount alternator with an internal regulator, a BB pulley section, and no plug, so connector and mounting details need to be checked carefully against the vehicle or machine being serviced.

Key dimensions include 68mm inside mounting legs, 17mm pivot hole diameter, 13mm adjusting hole diameter, and 215mm mount centre to centre. The pulley outside diameter is 80mm, and the unit weighs 11kg. These measurements are important when comparing the alternator to the original installation point.

This alternator is listed for Nikko applications and appears against a range of heavy vehicle and equipment references, including Hitachi, Isuzu, and Mitsubishi Fuso. As with any rotating electrical component, the most reliable check is still the part number, mount style, and measured dimensions before ordering.

The unit is supplied new and carries a one year warranty. For buyers replacing a 24V 50A alternator, the combination of internal regulation, twin leg mounting, and the no plug note makes it important to confirm the existing wiring, brackets, and pulley arrangement before fitting.

Application and Buying Notes

Before ordering, compare the part number NXA9710, the 24V rating, and the 50A output with the unit being replaced. On alternators, a close match in voltage is essential, and output rating should be checked against the charging requirements of the original system rather than assumed from appearance alone.

Mounting measurements matter as much as the listed type. This unit has 68mm inside mounting legs, a 17mm pivot hole diameter, a 13mm adjusting hole diameter, and 215mm mount centre to centre. If any of those points differ from the existing alternator or bracket layout, installation may not be straightforward.

The pulley details also need attention. The pulley outside diameter is 80mm and the pulley section is BB, so belt alignment and belt profile should be checked before fitting. A mismatch here can affect drive alignment and wear, even when the alternator otherwise appears similar.

Because the note states no plug, the electrical connector arrangement on the vehicle or machine must be verified. The alternator is fitted with an internal regulator, so the harness and plug style need to suit the replacement unit exactly. If the original alternator uses a different connector arrangement, additional parts or adaptation may be required.

This is a new unit and carries a one year warranty. As with any alternator replacement, it is sensible to inspect the battery condition, belt condition, and charging circuit connections at the same time, because a fault elsewhere in the system can affect the performance of a new alternator.

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 NXA9710 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 50A. Part number NXA9710 should be checked first. Listed voltage is 24. Listed output rating is 50. 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 BB. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number NXA9710, 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.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 24 and output 50 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm compatibility using part number NXA9710, the 24V 50A specification, the twin leg mount, the 80mm pulley, and the listed mounting dimensions. Do not rely on appearance alone; check the existing unit, wiring connection, and application details before purchase.
