RobM626 Posted March 1, 2018 Share Posted March 1, 2018 Hello I’m new on this forum but have been reading it for a couple years. i have a 2000 mack rd dump with an e7-350. Over the past year and a half have been chasing a vibration that no one can get right. Vibration is coming from clutch area and gets really bad around 1100rpm.... I replaced the clutch 3 times . Every clutch was worn prematurely with uneven wear on the facing. I changed the transmission, pto, vibration damper, motor mounts. Also did a camshaft job, 6 injectors and an oil pump. Everytime I put the new clutch in, I leave the shop and it’s great for a couple days then slowly but surely it comes back... I hear the clutch chattering constantly. If I put it in gear and let it coast it feels like a slight grab and slip... while driving if you press and release the throttle you feeling like there’s slack in the driveline... I’m up to 35k $ in repair bills and the truck still isn’t running right... Any ideas? Quote Link to comment Share on other sites More sharing options...
