Cummins 3283330 Starter Motor | Seven Star LLC
Overview
The Cummins 3283330 starter motor is a genuine Cummins starting motor used to crank diesel engines, identified by the Cummins part number 3283330. According to the official Cummins parts information, this starting motor is used primarily on Tier 1 5.9 litre B series engines, which covers the widely used Cummins B3.9 and B5.9 industrial engine family.
The original listing identifies the application as a portable generator set powered by a Cummins 6BTA5.9-G2 diesel engine, so this example is the Cummins 3283330 starter motor for that engine configuration. Starting motors are wear items in genset and industrial engine service, and keeping the correct OEM part number on hand avoids extended downtime when the installed starter fails.
Engineering & Design
The 3283330 starting motor is a DC electric motor that engages the engine flywheel ring gear to crank the engine until it fires. As a Cummins OEM part, it is designed to the mounting, drive and electrical characteristics of the B series engines it serves, which is why matching the part number to the engine build matters for correct fit and reliable starting.
For the 6BTA5.9-G2 genset application in the original listing, the starter must deliver reliable cranking over the full service life of the set, including cold starts and repeated start cycles. Genuine Cummins parts supply gives maintenance teams confidence in the drive engagement and torque characteristics of the motor.
