This is what it looks like, only the outer part seems to be damaged just a bit. On this photo, the lockring is not as much on the inside as mine, so here it is 50/50 if my tool would work tho I wouldn't swallow poison it would. http://user.it.uu.se/~embe8573/bike/bb.jpg That's a European variant of the USA OPC.

The bike seems to be upside down but it appears to be the L.H. side of the B.B. which is, I believe the adjustable side. If so you first loosen the lock ring, which is usually the outer ring, in order to remove the inner adjustable cone, don't you? 100% the way I understand it. However I have been unable to get a grip on the (outer) look ring with the "hook" tool as it is too far in, so the outer ring will block the "hook" from getting there. This is often the case! Sometimes it is grippable with the hook but often not so for this exact reason. I don't know if that is an error in construction or wear and tear but I don't think so (either) because it makes sense the lock ring must be right next to the outer ring, i.e. screwed in as far as to make solid contact. I didn't try the pin wrench which was suggested but I'll buy one ASAP and then I'll try it. It makes sense looking at the BB. The "hook" tool makes sense looking only at the lock ring in isolation, but as it is on many those bikes it won't get there by far. When I get the pin wrench I'll report back. -- underground experts united http://user.it.uu.se/~embe8573 |

Ahh, jargon rears its ugly rear. This, right? http://www.yellowjersey.org/ashta.jpg It is a OPC but I can't say if it is exactly like that. Use any big wrench on the locknut. It's reverse threaded. Once loose, the cone usually turns with fingertips or if not any implement such as a screwdriver. Again, oil treads which can be very helpful. OK, it is not that because any big wrench won't work what I can see (?). I think the pin wrench will work because the lock ring has two holes and it is loose in the sense nothing blocks it if one could just get a grip and rotate it out. p.s. Didn't you write about this a few months ago? I've done this two times, once on a REX and once on a Crescent. Those times I grabbed the outer ring with a pipe wrench and used the angled screwdriver/hammer approach to knock the lock ring loose. Apart from being obviously the wrong way this made both rings deformed/notchy, so this time I wanted to do it right. But the "hook" tool cannot do it what I can see. The problem back then was how to remove the crank once the L.H. side is open. Some people got irritated because this is supposedly easy. But I didn't succeed on either. On the REX, the arm won't even enter the shell. On the Crescent, the arm will enter it but it won't go all the way out on the other side. So I didn't solve that problem but I thought if I can do it this time perhaps it will become apparent what is different from them bikes. -- underground experts united http://user.it.uu.se/~embe8573 |

The outer ring blocks the tool from entering from the side. I need to enter the lockring from the front. The tool itself can then be "sideways". I'll get that pin wrench tomorrow and have a report how that works -- underground experts united http://user.it.uu.se/~embe8573 |
