Friction shifter squeal, fix?

wrote: Folks, Lately my old Shimano 600 friction shifter levers let off an annoying squeal when moving them. Shifting is ok but it's embarrassing when other road bikers are around. A drop of oil didn't help. Can I use some sort of lube on their inner surfaces? LiquiMoly LM48 maybe? Some other trick? Wanted to ask here before I do something where they'll never work right anymore and someone will say "Oh, you shouldn't have done that". There isn't much inside a (I am assuming R.H.) 600 shifter. I think I would ask whether you have the selector set all the way to friction, or indexed, and whether you have disconnected the shifter from the derailer and tried that? You might want to have a look at: https://shimanostioverhaul.wordpress...ar-reassembly/ or http://tinyurl.com/ptrpcp2 or http://bicycles.stackexchange.com/qu...r-installation I've got 600 - 7 speed shifters on the"New Old Bike" that I took off a previous "new old bike" and all they do is click :-) -- cheers, John B. |

I just tried your recipe with the FD shifter and ball bearing grease sparingly applied. Now it needs to be tightened a bit more than usual in order not to gradually slide back and it makes a slight grinding noise but ... no more squeal. Next ride is tomorrow and if this works I'll do the same with the RD shifter. The inner black steel ring with the two locking notches had some rust on it. Grease or machine oil work equally well for that. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Just did, per Tom's and Andrew's advice. Seems to work. All I wanted was that it stops emitting this loud squeak every time I shift and it did stop. -- Regards, Joerg http://www.analogconsultants.com/ not interested in what cawsed squeaking ? whatill the rear wheel squeeks n falls off like the alleged nut on Concorde's runway I never had an aircraft try to take off after me.

Pure friction, they do not have any index function. Sometimes I wish they did but then again some day when the last UG hub is through (it is showing signs) I want to switch to HG cassettes and put 7 gears on there. But friction is ok on the road bike because I don't shift nearly as much as on the MTB. -- Regards, Joerg http://www.analogconsultants.com/ |

But I do frequently forget to lubricate those points, and it makes for tough shifting. -- - Frank Krygowski |

But probably not the grimy toothbrush I use on the MTB chain :-) I did use a toothbrush for this job yesterday but then bearing grease, hoping it'll stick a little longer in there. One remarkable cleaning device I discovered recently are disposable interdental brushes. They look like microscopic bottle brushes and are excellent in cleaning small crevices on bicycles, most importanly inside the chain links. So now I use them for my teeth and instead of tossing I clean the little brushes, let them dry, use them once more on the bikes, then throw them away. It didn't speed up the MTB chain maintenance a lot but the chain is cleaner afterwards. -- Regards, Joerg http://www.analogconsultants.com/ |
