Nikko Alternator 24V 50A NXA9715

This Nikko alternator is a 24V, 50A unit identified by part number NXA9715. It is a new alternator with an internal regulator, twin leg mount, and brushless design, which is important when matching it to the correct charging system and mounting arrangement.

Key physical details include 68mm inside mounting legs, a 14mm pivot hole diameter, a 12mm adjusting hole diameter, and 225mm mount centre-to-centre. The pulley outside diameter is 82mm with a BB pulley section, so the belt and bracket setup should be checked carefully before purchase.

This alternator is listed as suited to Nikko units and carries a one year warranty. It also weighs 9.48kg, which can be useful when comparing against the unit being replaced or confirming you are looking at the same style of assembly.

Application coverage is broad across industrial and equipment makes including Case, Hitachi, Isuzu, John Deere, and Komatsu. Because alternators can vary by mount, regulator type, pulley section, and dimensions, matching the part number and installation details remains the safest way to buy the correct unit.

Application and Buying Notes

When comparing this alternator to an existing unit, start with the part number NXA9715 and then confirm the mounting dimensions. The 68mm inside mounting legs, 14mm pivot hole, 12mm adjusting hole, and 225mm mount centre-to-centre are the most practical checks for a correct physical match.

The charging specification is 24V at 50A, so it suits equipment built around that electrical requirement. If the system on the machine uses a different voltage or output level, this alternator should not be assumed to be a direct replacement.

The internal regulator and brushless construction are important identifying points. They help distinguish this unit from externally regulated or different internal layouts, which can look similar at a glance but are not interchangeable without checking the application details.

The pulley details also need attention. This unit has an 82mm outside diameter pulley with a BB section, so belt alignment and groove style should be verified against the removed alternator or the machine specification before ordering.

The listed applications include multiple Case, Hitachi, Isuzu, John Deere, and Komatsu models, but that list should still be checked against the actual machine and engine setup. Matching by make alone is not enough when alternator mounts and electrical configurations can vary within the same family.

If you are replacing a worn alternator, comparing the weight of 9.48kg and the existing mounting style can help confirm you are looking at the same type of assembly. That said, the final check should always be the part number and the dimensions on the unit already fitted to the machine.

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 NXA9715 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 2 ALTERNATORS, Part No. NXA9715, Brand NIKKO, Description Nikko Alternator 24V 50A, Adjusting Hole Diameter 12, Pin Code IR37, Power Rating (Amp) 50, Pulley Section BB, Suits Unit Make Nikko.

Nikko Alternator 24V 50A. Part number NXA9715 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 NXA9715, 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.

Available application references include CASE CX700B, CASE CX800B, HITACHI EX120-2, HITACHI EX120-3, HITACHI EX400-3/LC-3, HITACHI EX400-3C. 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 with part number NXA9715, the 24V 50A specification, and the listed mounting and pulley dimensions before ordering. The application list is helpful, but the safest approach is to verify the actual alternator on the machine against the dimensions and regulator type shown here.
