Removing cogs from a Shimano (Singapore made) freewheel?
I have a Shimao 7 speed freewheel made in Singapore. I want to take the cogs off the body. The 7 cogs are silver and there is black ring with 8 recesses on its outer edge. This ring is right beside the smallest cog. I'm assuming that this ring is screwed on. Does anyone know if this is the case? If so, what direction does it come off?
Thanks and cheers |

Thanks and cheers Normal RH thread, unscrew like a jar lid. Good question though. It's not like the freewheel body cover plate which must obviously be reverse threaded. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

A freewheel vise to hold the low gear sprocket is the usual tool if you meant unscrewing the outer sprocket lockring: http://www.yellowjersey.org/photosfr...st/FWVISE2.JPG What he doesn't need is a chain on a stick because the high gear sprocket is splined, not threaded, on modern freewheels. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Ah, I have always used a chain whip to stop the cluster or cassette rotating anticlockwise while unscrewing sprockets or lock rings, but I've always disassembled them while they were built into a wheel. I can see a freewheel vise would be better if the cluster or cassette was not on a hub and built into a wheel. -- JS |
