The listed measurements are 69mm inside mounting legs, a 14.5mm pivot hole diameter, a 12.5mm adjusting hole diameter, and 225mm mount centre to centre, so it is important to compare those points against the alternator currently fitted.\u003c\/p\u003e\n\u003cp\u003eThe pulley information should also be checked carefully before ordering. This unit has an 82mm pulley outside diameter, AAA pulley section, and the note says it suits a 13A type belt. If the pulley section or belt type does not match the machine, the alternator may not be suitable even where the electrical rating appears similar.\u003c\/p\u003e\n\u003cp\u003eThe regulator is internal and the alternator is brushless, so it should be compared with the existing unit on both the electrical and mounting side. The part number NXA9721, pin code IR94, and Nikko application details are the most reliable identifiers available here. If the old unit is damaged or unreadable, measure the mounting points and pulley dimensions before placing an order.\u003c\/p\u003e\n\u003cp\u003eThis alternator is new and carries a one year warranty. For a commercial machine or equipment that works in harsh conditions, the stated build note is relevant, but it should still be treated as a replacement component that must match the original specifications. Confirm the machine’s charging system requirements before fitting, especially on 24V equipment where the incorrect unit can create charging issues.\u003c\/p\u003e\n\u003cp\u003eBefore 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.\u003c\/p\u003e\n\u003cp\u003eFor workshop, fleet, and equipment applications, accurate identification of part number NXA9721 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.\u003c\/p\u003e\n\u003cp\u003eRelevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty One Year, Inside Mounting Legs 69mm, Pivot Hole Diameter 14.5, Pulley Outside Diameter 82mm, Regulator Type Internal, Voltage 24, Alternator Mount Twin Leg, New \/ Reman.

These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eMount style is Twin Leg. Regulator type is Internal. Pulley configuration is AAA. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.\u003c\/p\u003e\n\u003cp\u003eFor part number NXA9721, 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.\u003c\/p\u003e\n\u003cp\u003eFor a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 24 and output 50 should be checked carefully.
