Eaton 18spd Intermittent Problem

[MSPOIRIER]

Thanks, I did that a couple weeks ago, breather wasn't bad but I cleaned it anyways. I am going to try the range cylinder Orings today. For 25$ from Eaton it is worth a shot to try one last thing. According to the Eaton manual the "9 Series" which is what I have the range cylinder cannot be removed to change the inner oring seal without removing the AUX. Can anyone confirm or deny this claim? Looks like the fork needs to be removed from the inside. I will remove the cover and have a look to see if I can get the big middle seal anyways..
