First I tried to just put the bellow back over the lip and re-secure the inner metal ring clamp. That worked and stayed on - but when draining and spinning popped off again. I replaced the entire bellow and inner metal ring clamp this time. My old drum bellow liner was over 16 years old - NO holes or tears, just really worn down and out. So, I replaced the entire system. I am a single 43-year-old mom and was able to do this on my own. It did take me over 3 hours though. I had a really really hard time getting both the inner metal ring clamp back on and the spring metal ring clamp on at the end...but I finally did it. No leaking and stayed on during spin and drain cycles! Important to have the holes of the bellow at the bottom so it can drain.
