yes, now I see what you mean, the o-ring is between the sleeve and the bearing! Thanks, I may have thought it was just some wood hair, lol
It happens
One time I sliced myself wide open right behind my ankle and to the top.
I was laying down while my buddy was wraping it up and looked to the side and saw what looked to be a piece of white rubber about and 1" 1/2 long and about 1/4" in the middle. I picked it up and asked what it was ..it crossed our minds that it may have come out of my leg but it was so clean looking...I figured it couldn't be so I had it between my teeth checking it out then bit down real hard, shearing it in half with my teeth and throw it back on the ground.
Meanwhile after x-rays, the doc comes back in and says I will need surgery and there was a large portion of my tendon missing.
All I was thinking is..oh G-d..I hope my buddy doesn't say anything.
As soon as the doc left he slaps me on the shoulder like he just made this huge discovery, then says...That was that rubber looking thing you ate remember? Lol
So yeah... always pay attention to detail especially when they could be your own body parts.
I'm like a misbehaving child.
