OEX Alternator 24V 40A Nikko Style NXA9701

The OEX Alternator 24V 40A Nikko Style is a new rotating electrical unit with part number NXA9701. It is rated at 24 volts and 40 amps, uses an internal regulator, and is set up for clockwise rotation. If you are replacing a Nikko-style alternator, the key checks are the part number, mounting arrangement, pulley type, and electrical connections.

This unit is supplied as each and suits Nikko applications where the mounting and drive details line up. The alternator uses a twin leg mount with 72mm inside mounting legs, a 14mm pivot hole diameter, a 12.5mm adjusting hole diameter, and a 189mm mount centre-to-centre measurement. Those measurements are the practical checks that matter before ordering.

The pulley is 82mm outside diameter with a BB pulley section, and the alternator weight is 6.34kg. Wiring notes supplied with the unit are ignition wire and red lamp wire, with blue lamp wire noted as well. For commercial or off-road equipment, confirming these details against the removed unit is the safest way to avoid an avoidable mismatch.

Application and Buying Notes

Before ordering, compare the alternator you are replacing with the key identifiers on this unit: part number NXA9701, 24V voltage, 40A output, internal regulator, clockwise rotation, and twin leg mounting. The 72mm inside mounting legs, 14mm pivot hole, 12.5mm adjusting hole, and 189mm mount centre-to-centre are the measurements most likely to determine whether the unit will physically suit your application.

The pulley details also matter. This alternator has an 82mm outside diameter pulley with a BB section, so it should be checked against the belt and pulley arrangement on the original unit. If the pulley profile, offset, or belt match is different on the equipment, the alternator should not be assumed to fit just because the voltage and amperage look close.

The wiring notes supplied are ignition wire, red lamp wire, and blue lamp wire. That makes it important to confirm the connector and warning lamp wiring on the machine before installation. Small differences in alternator wiring can affect operation even where the casing and mounts appear similar.

This alternator is listed against a wide range of equipment families, including Nikko applications, some Hitachi excavator models, Isuzu industrial and truck references, and several Komatsu, Kato, Sakai, TCM, and Kawasaki applications. Because those groups contain multiple variants, the safest purchasing method is still to match the removed unit by part number and measurements rather than relying on model name alone.

The listed warranty is 3 years for passenger use and 1 year for commercial use. That warranty detail is useful, but it does not replace the need to confirm the application, mount type, pulley section, and rotation before fitting. If the alternator is being sourced for commercial machinery, checking the exact vehicle or equipment reference is especially important.

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 NXA9701 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.

OEX Alternator 24V 40A Nikko Style. Part number NXA9701 should be checked first. Listed voltage is 24. Listed output rating is 40. 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 NXA9701, 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 fitment by matching part number NXA9701, 24V 40A rating, Nikko-style application, twin leg mount measurements, pulley specification, rotation, and wiring details against the existing alternator and equipment application before purchase.
