cassette clockwise arrow 40 nm
Hello again everyone!
Now I've moved on from the Swedish and Norwegian standard bikes of the 70s into the most recent of bike technology, namely the mountain-bike or "MTB"! I read on the cassette that you should pull it 40 nm. There is even an arrow pointing the way. It is the well-known way, but OK. I know there is a tool for this - torque wrench, right? I don't have one, but I do have the everyday half-inch ratchet, and the special socket with all the teeth (?) - of 40 nm, I know only this is a lot and the reason I know this is every time I remove it, it is stuck like, very firmly! When I pull, I hear a crash sound three or four times. This seems to be normal. I asked the local guru who did bikes since the 80s. He also claimed he was a master after only two years. Anyway he suggested it was sand! But I'm not that stupid I don't make the parts rudimentary clean before I operate them. So it is not sand. Besides the sound is much to big to be sand. Anyway what do you guys make of all this? -- underground experts united .... http://user.it.uu.se/~embe8573 Emacs Gnus Blogomatic ......... http://user.it.uu.se/~embe8573/blogomatic - so far: 69 Blogomatic articles - |

Get a torque wrench and tighten it to 40nm. Indeed, I'm all for getting the right gear! Eventually I hope to own every single tool there is for doing bikes. And I'm getting closer! I even have ancient Torpedo tools ("hook wrenches?") for their ring lock nuts - you need two of those to seal their 3-speed hub - the only tools for the entire hub by the way! Nowadays, it is almost fun realizing there is a tool you don't have, at least if you can get it A torque wrench which is half-inch, 45 cm, and 28-210 Nm is 339 SEK ~($44, £36, or €42) at the quality-tool shop so yes, in the long run I sure hope to get one of those, God willing. -- underground experts united .... http://user.it.uu.se/~embe8573 Emacs Gnus Blogomatic ......... http://user.it.uu.se/~embe8573/blogomatic - so far: 69 Blogomatic articles - |

I have a couple of torque wrenches, but my cassette took does not have a socket wrench fitting -- so I use a adjustable wrench. Go ahead and hate on me, but I just give the lock ring a good yank. With the serrations, loosening is unlikely. But now I feel bad and will go out and find a tool with a socket wrench fitting. -- Jay Beattie |

You don't need a torque wrench but it's nice to have one and the adapter to work with your cassette key. Otherwise tighten firm and not real tight. I think that the "crash" you're talking about is the serrations/semi-ratchet teeth on the inside of the lock ring. These are to keep the lock ring from backing off if it isn't tight enough. The cassette should NOT rattle. If it does there is an incorrect spacer. I assume that you know the difference between a freewheel and a freehub. If you have a vernier caliper you can measure the spacers and let Muzi know and he can straighten things out. |

During the Russian revolution civil war the Reds didn't have any visible rank system to tell their soldiers apart. Still, everyone knew who was the boss. A good system, I'd say... Otherwise tighten firm and not real tight. I think that the "crash" you're talking about is the serrations/semi-ratchet teeth on the inside of the lock ring. These are to keep the lock ring from backing off if it isn't tight enough. So, the lock ring bolt has serrations on the inside that has a semi-ratcheting property... but contrary to a real ratchet which goes "chirr chirr chirr" this goes "crash crash crash" with proportionally the more power in between and larger chunks of movement? Man, I have a bucket of worn out cassettes. Perhaps picking one apart is educational... The cassette should NOT rattle. If it does there is an incorrect spacer. I don't know if "rattle" is the sound. When fiddling with the cassette some two or three (?) sprockets were moving along, possibly making some sound, actually I don't remember, but if they did it wasn't very loud or alarming in character. The sprockets were not spinning but the amount of force to make them move was minimal. They seemed to be moving in small chunks. The cassette was brand new as said. When I put it on and pulled with the ratchet and socket, it crashed into a new position I think three times, and possibly if I had continued to pull, I could make more such sounds/movements. With every crash sound, it moved perhaps 30 degrees. I assume that you know the difference between a freewheel and a freehub. OK? If you have a vernier caliper you can measure the spacers and let Muzi know and he can straighten things out. This particular cassette is already on a bike but I will see if I can pick apart another, spent cassette and get back to you. However it could be another brand but why not. -- underground experts united .... http://user.it.uu.se/~embe8573 Emacs Gnus Blogomatic ......... http://user.it.uu.se/~embe8573/blogomatic - so far: 69 Blogomatic articles - |

I advise you not to listen to anyone else on this subject except Al Muzi. You don't need a torque wrench but it's nice to have one and the adapter to work with your cassette key. The Park cassette tool -- a least the one I have -- doesn't have a female socket fitting. One could use a 1" socket on the end of a torque wrench. It appears that the Park tool is sized for a 1" wrench/socket. Or one could buy the Shimano tool that has a female socket fitting. 40nm is about 30 foot pounds -- about the recommended torque for old square drive crank bolts. It would take a lot of torque to strip a steel freehub body and steel lock ring, and if it were under-torqued (but still given a good twist), the serrations would hold the lock ring. But, again, its always good to follow recommended torque specs. -- Jay Beattie. |

When you tighten the lockring at first you'll hear a number of clicks as those serrations engage each other. Cheers |
