Cummins ISX Flywheel Impact Socket 3/4" Dr. 21MM 12 PtThe ATC21MMISX Cummins ISX 21mm Flywheel Impact Socket is a purpose-built heavy-duty tool designed for servicing flywheel and crankshaft-related fasteners on Cummins ISX diesel engines. Engineered to withstand high torque loads, this impact-rated socket provides the strength and precision required for removing and installing flywheel bolts in demanding service environments.
Flywheel fasteners on ISX engines are typically torqued to high specifications and may be secured with thread locking compounds, making removal challenging without the correct tool. The ATC21MMISX is manufactured from impact-grade materials to handle these extreme conditions while maintaining proper fitment to prevent fastener rounding or damage.
Its deep, reinforced design allows for proper engagement on flywheel bolts, even in recessed or limited-access areas around the rear of the engine. Whether used with impact tools or breaker bars, this socket ensures reliable performance during engine teardown, clutch service, or flywheel replacement.
Built for durability and consistent use in professional diesel repair shops, the ATC21MMISX is an essential addition to any Cummins ISX service toolkit.
