Overview — Fan Battery Charging Alternator A029T484
A029T484 is the fan-cooled battery charging alternator used on CUMMINS diesel engines, generating charging current for the batteries and supplying the electrical loads of the machine. We can supply this part as well as related CUMMINS electrical components, in stock or available on order — welcome to enquire by part number.
Parts Characteristics
The alternator is built to the original output and mounting specification, with a built-in fan that draws cooling air through the unit while the engine runs. The rotor and stator windings are matched to the rated output so the alternator maintains voltage across the operating speed range, and the internal regulator holds the system voltage at the specified level. The mounting bracket, pulley and electrical connections match the original drive arrangement, and the unit is protected against oil and moisture ingress at the points where cables enter. As an OEM-spec replacement, it restores the designed charging performance without changes to the existing brackets or wiring.
Applicable Models & Applications
This alternator is used across CUMMINS engine families in construction, industrial, marine and generator applications where the original fan-cooled charging unit is fitted. The same charging duty is covered on related engine builds, and the alternator suits machines that operate with high electrical loads, including machines with electric starting, lighting and auxiliary systems. Confirm the output rating, pulley size, mounting foot spacing and connection style against the alternator removed from your engine before ordering.
Maintenance & Replacement
Monitor charging performance with a voltmeter at the battery terminals, both at idle and at rated speed. A charging fault shows as a low battery, slow cranking, or an alternator that runs hot after a long working day. Before replacing the alternator, check the belt condition and tension, the battery condition, and the wiring for loose or corroded connections, since these faults can damage a new unit. When fitting the replacement, tighten the mounting bolts, align the pulley with the drive belt, and torque the belt to the specified tension. After installation, verify that charge voltage is within the specified range and that the charging warning lamp extinguishes correctly.
Price Reference (USD)
The reference price for this Alternator (A029T484) is approximately USD 80 – 220 per unit depending on brand grade, output rating, quantity and shipping destination. This is a planning estimate only — confirm current pricing and availability with our sales team before ordering.
Value & Service
Charging faults cause expensive downtime because every electrical fault points back at the battery first, so we verify A029T484 against the original CUMMINS reference and confirm the output rating, pulley and mounting before dispatch. We keep the alternator in stock and can ship worldwide with tracking, and our technical team can advise on belt tension and cable sizes to protect the new unit from the overload that may have failed the old one. Quantity pricing is available for fleet and rental operators.
