Interesting. I just spoke with Ryan at RJM earlier this week to discuss a "rubbery-like" squeak that I traced to the Gen 2 HD CMC. The noise would appear at the upper-end of the clutch pedal travel every time the pedal was pushed and released. Ryan suggested that I apply some Super Lube synthetic grease in and around the opening where the clutch rod enters the cylinder. He suspects that the upper seal simply needs some lubrication. I'm yet to try it. However, as part of our e-mail exchange Ryan mentioned that he has had no complaints/failures to date with the Gen 2 version of the CMC. He may respond to your post since he occasionally posts on the forum ... or you could send him an e-mail explaining the problem. He is usually very quick to respond and always helpful. Moreover, he stands behind his products. Also, you might want to check to ensure that the clutch rod is aligned correctly. It needs to push straight in and out. If it's angled too much, it can damage the seals, and cause the CMC to fail. Finally, I noticed that the engagement point was high after I installed the Gen 2 CMC along with the Version 3 RJM clutch pedal assembly. I lowered it through a combination of adjusting the length of the clutch rod as well as the AFP setting according to Ryan's instructions. This helped. Again, it was necessary to align the clutch rod properly after each adjustment. Trust this helps. Keep us posted as to what you discover. My advice: Contact Ryan and discuss the issue with him.
