Nikko Alternator 24V 50A NXA9729

The Nikko Alternator 24V 50A, part number NXA9729, is a new alternator supplied as an each unit for rotating electrical applications. It is listed as an OE product and carries OEM number 32G68-00101, so the part number and application details should be checked carefully before ordering.

This unit is a 24 volt alternator with a 50 amp power rating, internal regulator, brushless note, and twin leg alternator mount. Key mounting dimensions include 68mm inside mounting legs, 225mm mount centre to centre, a 14.5mm pivot hole diameter, and a 12.5mm adjusting hole diameter.

The pulley is a 12 groove design with an 85mm outside diameter. Those physical details matter because alternators can share similar output ratings while differing in mount style, pulley setup, and hole spacing. Confirming the measurements against the existing unit is the most reliable way to avoid a mismatch.

Application and Buying Notes

Before ordering, compare the part number NXA9729 and OEM number 32G68-00101 against the unit currently fitted to the machine. The alternator is specified as 24V and 50A, so both the electrical output and the physical fit need to match the existing system.

Pay close attention to the mounting layout: this alternator uses a twin leg mount, 225mm mount centre to centre, 68mm inside mounting legs, a 14.5mm pivot hole, and a 12.5mm adjusting hole. These measurements are the practical checkpoints that usually matter most when matching an alternator.

The pulley details also need to line up. This unit has an 85mm pulley outside diameter and a 12 groove pulley section, which should be checked against the original alternator and belt arrangement before purchase. A correct voltage rating alone is not enough if the pulley or bracket arrangement differs.

The listed fitment references Kobelco ED150, Kobelco SK135SR, SK135SR-2, SK135SR-3, and SK135SRLC applications, including several year references. Even with those application notes, the safest approach is to confirm the machine model, year where relevant, and the identifiers on the old unit to make sure the alternator matches exactly.

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 NXA9729 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 NXA9729 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 12 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number NXA9729, 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 fitment using part number NXA9729, OEM number 32G68-00101, and the alternator’s mounting and pulley dimensions before ordering. If the existing unit differs in mount style, hole spacing, pulley section, or voltage rating, it should not be assumed to be compatible.
