Greetings, Comrades!
I have a 1990 K75S with 41,000 miles on it. The fork seal on the right-side fork (from the riding position) started leaking slightly last summer and I decided to change both seals and put some Rancho boots on as well. I did all of the due diligence that I could before starting this job - Clymer's manual, all the posts I could find on this fine site, youtube posts, etc. Felt pretty confident that I could pull it off myself.
My problem arose when I tried to remove the fork seal from the black inner tube. There didn't appear to be a snap ring or holding clip in place and when I tried to gently pry out the seal with a small flat-head, still no luck. So, I purchased a seal puller from Harbor Freight, hoping that this would do the trick. I was able to get the seal out, but I fear that I destroyed my inner tube in the process. Turns out that the inner tube on my bike is a Brembo # 1 454 325. Instead of a snap ring to hold in the seal, there is a little metal lip that is part of the tube itself. The seal sits under this lip and than there is a tiny metal band that sits inside the seal which I assume acts to provide tension to hold the seal in place. Unfortunately, I damaged this lip (see attached photo) when I was trying to get the seal out.
Have any of you folks worked on a Brembo inner tube before? Is my tube ruined for good? Any help that you would provide would be much appreciated.
