Hello,
I'm posting from Germany...I'll do my very best, but can't guarantee for 100% language-accuracy
I am trying to revive an old "shop-bike" (Katarga Storm-Race) and after many other problems, the bottom bracket won't move a bit! I am equipped with an bottom bracket tool from Shimano (TL-UN 74-S) and an larg adjustable wrench to get a wrench size of 32mm.
On the images you can see the drive (kurbel_1.jpg) and non-drive side (kurbel_2.jpg) of the bracket.
I am quite irritated because there are a few of the 20 cotters (?) missing in the tool mount on the drive side. (green circle in the image.) There is also an eight-edge nut around the shaft. (blue arrow) There is no contact face on the non-drive side, as I know it from Shimano cartridge bottom brackets.
If I insert the Shimano-Tool, and try to loosen it with the adjustable wrench I am frightened to destroy either the tools or the frame of my bike
What should I do?
What bottom bracket is it and how to get it out?
Thank you very, very much!
