Simplify maintenance with our Endurant replacement clutch and flywheel kits.

OEMs now recommend that an out-of-spec flywheel be replaced rather than machined due to the unique designs and tighter tolerances of flywheels in AMT drivelines. Eaton is now offering service kits which include an Advantage Automated clutch and a genuine Cummins Flywheel for the Endurant automated manual transmission. Simply order the kit part number for your OEM/engine combination.

Flywheel machining is no longer recommended

A machined flywheel put back into service may cause alignment issues, fault code generations, and the inability to complete a clutch calibration cycle. OEMs recommend that the flywheel be intensively inspected every time a clutch is replaced: a flywheel out of spec should be replaced rather than machined.
