I'm getting weird noises coming from the bottom bracket (BB from now on), and I wanted to extract it to check if the problem is there or not.
The guide video I used is no longer public (free) as when I saw it the first time.
I've been successful extracting on another bike, but on this one, I have two issues:
On the right side (drive side), made of metal, the extraction key doesn't fit! the key seems to be about 2mm wider than the circumference of the side, as seen on the picture below. I assume something distorted this side, this bike fell once, but I doubt this was damaged by that.
The left side is made of plastic, and my hope was (because of the issue on the right side), to unscrew this side first, but it is very tight and I am fearful of it breaking if I apply more strength. By the way, the key fits perfectly on this side.
I've done this before on another BB and it came out just fine.
A picture to illustrate this:
Finally the question(s):
Is there a different technique to extract this BB?
Is there hope in salvaging this BB? it may not be the part making the noise.
Any guess on why the right side is tighter?
