My fleet mechanic of 12 years has replaced crank dampner and complete clutch system.Cummins engine dealer wants a crack at the problem. I am very unsure of the outcome as thousands of dollars has spent with still no satisfaction. Has anyone else had this problem to give me direction. Thank you

Maybe motor mounts, or crank, or injectors need to be adjusted have you ran overhead? Maybe fuel issue, or bad injector.
