Nikko Alternator 24V 50A NXA613

This Nikko alternator is a new 24V, 50A rotating electrical unit supplied as each, with part number NXA613 and one-year warranty. It is listed with an internal regulator, twin leg alternator mount, and an 8 groove pulley, so the physical mounting and drive arrangement are important checks before purchase.

Key dimensions include 69mm inside mounting legs, 14.5mm pivot hole diameter, 12.5mm adjusting hole diameter, 225mm mount centre to centre, 17 shaft dimension, and an 80mm pulley outside diameter. At 9.4kg, this is a substantial alternator, so confirming the bracket spacing and pulley alignment on the vehicle matters.

The stated application is Isuzu N Series, NQR450, with 4HK1 engine. There is also fitment data attached to the listing that references a wider range of equipment and vehicle groups, but the only explicitly supplied application in the product facts is the Isuzu N Series NQR450 with 4HK1 engine. Where fitment is concerned, the part number and mounting dimensions should be used as the final check.

Application and Buying Notes

Before ordering, compare the vehicle’s existing alternator against the key identifiers here: Nikko NXA613, 24V, 50A, internal regulator, twin leg mount, and 8 groove pulley. These details are the most useful checks when matching the replacement to the original unit.

Mounting measurements are especially important on alternators, because a similar-looking unit can still differ in leg spacing, pivot size, or adjuster size. This unit lists 69mm inside mounting legs, 14.5mm pivot hole diameter, 12.5mm adjusting hole diameter, and 225mm mount centre to centre, so those figures should be checked against the original assembly.

The listed application is Isuzu N Series NQR450 with 4HK1 engine. If the vehicle is being used for a repair rather than a known part-number match, confirm the original part number and inspect the pulley section, shaft dimension, and regulator type before fitting. The 80mm pulley outside diameter and 17 shaft dimension are useful checkpoints when comparing units side by side.

Because this alternator is 24V and rated at 50A, it should only be considered where the vehicle’s electrical system matches those specifications. Using the wrong voltage or mounting style can lead to installation issues even if the unit appears close in size.

For workshop or fleet use, the 9.4kg weight and one-year warranty are practical details to factor into handling and replacement planning. Keeping the old unit until the new one is checked against the brackets, plug arrangement, and pulley alignment is a sensible way to avoid downtime.

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 NXA613 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 NXA613 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 8 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number NXA613, 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 CX210B, CASE CX210C, CASE CX210C 2015, CASE CX225, HIDROMEK HMK200W, HIDROMEK HMK200W 2017. 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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm fitment using part number NXA613 and the application details for your vehicle. The safest match is by part number, regulator type, voltage, pulley section, and the mounting dimensions listed above.
