OEX Alternator 24V 45A Cummins Style NXA9732

The OEX Alternator NXA9732 is a new 24V, 45A unit built in a Cummins style configuration. It suits a Cummins application and is identified with OEM number C4938600, which makes the part number and application details the first checks before ordering. This is a twin leg alternator with an internal regulator, supplied as a 7.38kg unit.

Key mounting details are provided for direct comparison: inside mounting legs measure 101mm, the mount centre to centre is 198mm, the pivot hole diameter is 13mm, and the adjusting hole is M12x1.75. The pulley is 60mm outside diameter with an 8 groove section, and the unit includes a phase (N) connection. Those points matter when matching the replacement to the original alternator.

OEX supplies this alternator as a new rotating electrical part, backed by a 3 year passenger and 1 year commercial warranty. The brand notes also state that OEX products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with ISO9001 certified factory support for engineering, testing and quality control procedures.

Application and Buying Notes

Before ordering, compare the original alternator against the key dimensions on this unit: 24V, 45A, twin leg mount, 101mm inside mounting legs, 198mm mount centre to centre, and a 60mm 8 groove pulley. Those details are often the quickest way to confirm whether the replacement will physically suit the machine or engine setup.

This alternator is listed for Cummins applications, but that alone is not enough to confirm a correct fit. The safest check is to compare the part number NXA9732 and OEM number C4938600 with the existing unit, then verify the mounting holes, pulley section, and the phase (N) connection before purchase.

Because this is a new alternator with an internal regulator, it is intended to replace a compatible unit rather than be adapted to a different configuration. If the existing alternator is a different voltage, uses a different mount style, or has a different pulley arrangement, it should be matched carefully before fitting. The listed weight of 7.38kg can also help when comparing against the removed part.

Warranty cover is listed as 3 years for passenger use and 1 year for commercial use. That does not replace proper fitment checking, but it does give a clear reference for how the part is supported once installed in the correct application. For commercial equipment, it is especially important to confirm the machine model and alternator details before proceeding.

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 NXA9732 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.
