Nikko Alternator 24V 90A NXA9723 Twin Leg New Brushless

The Nikko alternator listed here is a 24V, 90A unit, part number NXA9723, and it is supplied new rather than remanufactured. It uses an internal regulator and a twin leg mount, with inside mounting legs at 69mm and a 225mm mount centre to centre measurement.

A key identifying point on this unit is the 70mm pulley outside diameter, along with a 14.5mm pivot hole and 12.5mm adjusting hole. The note also states it is brushless and supplied with an adaptor to suit HXK-32 and HXK-24.

This is a heavy-duty rotating electrical component with a listed weight of 10.2kg and a product note stating it is built to withstand the harshest environments. For buyers matching a replacement alternator, the part number, voltage, mounting style, and pulley size are the main checks before ordering.

Application and Buying Notes

Before ordering, compare the part number NXA9723, the 24V voltage, and the 90A output with the unit you are replacing. Those are the clearest starting points for confirming you are looking at the same alternator rather than another Nikko unit with a similar housing or pulley setup.

Mounting and pulley measurements matter just as much as the electrical rating. This alternator is a twin leg mount with 69mm inside mounting legs, 225mm mount centre to centre, a 14.5mm pivot hole, a 12.5mm adjusting hole, and a 70mm pulley outside diameter. If any of those dimensions differ on the existing unit, the alternator may not align correctly.

The note says the alternator is brushless and supplied with an adaptor to suit HXK-32 and HXK-24. That adaptor detail is useful, but it should still be checked against the vehicle or machine installation before purchase. The listed fitment groups cover Hercules, I-Bus, Isuzu and Kawasaki applications, yet final confirmation should still be made against the exact application details and the physical unit being replaced.

This alternator is listed as new, with an internal regulator and no warranty shown. For commercial and heavy-duty equipment, those details are important because they help set expectations around installation, maintenance, and whether the replacement matches the original electrical arrangement. A 10.2kg alternator is also a substantial component, so handling and installation should be planned accordingly.

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 NXA9723 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.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. NXA9723, Brand NIKKO, Description Nikko Alternator 24V 90A, Adjusting Hole Diameter 12.5, Pin Code IR97, Power Rating (Amp) 90, Regulator Type Internal, Voltage 24, Alternator Mount Twin Leg.

Nikko Alternator 24V 90A. Part number NXA9723 should be checked first. Listed voltage is 24. Listed output rating is 90. 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. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number NXA9723, 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 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HERCULES H.850, HERCULES H.850 2022, HERCULES H700, HERCULES H700 2022, I-BUS 500 SERIES, I-BUS 500 SERIES 2015. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm fitment by matching part number NXA9723, the 24V 90A specification, the twin leg mounting measurements, and the 70mm pulley details against the existing unit and application before ordering.
