I signed up on Startek EPC and have searched through there. I can see the repair seal rings but haven't found the tool nor the instructions for its use. I also have dug around and searched the DIY sections to no avail. This is apparently not a common issue, as I can imagine. I'm at the point of calling my local Indie that I trust. I just don't like to bother him about things like this. Unfortunately, I'm stuck and can't see where the solution lies.
