Freewheel removal woes
Hi Folks,
I have a set of wheels built on 1980 Campy Record hubs..36 hole. The front wheel repack was smooth. When I attempted to get the Suntour Winner Pro four prong freewheel off, it snapped a prong on the freewheel and on my removal tool. The LBS could not get it off either. So I removed the outer bearing cone, figuring that I have a few spare freewheels but I don't want to abandon this wheelset (second set of rims/wheels on the same hubs in 28 years). Unfortunately, clamping the freewheel body in my metal vise was also unsuccessful. I now ask the flotilla of experts here on r.b.t. for any suggestions. I have hand and power tools and IIRC, I put anti-seize on the threads of every freewheel I've installed for the last couple of decades. So, any hope from you folks?? -- Unthinking respect for authority is the greatest enemy of truth. ~Albert Einstein All wars come to an end, at least temporarily.

Since you've already decided to sacrifice the freewheel body, removal is just as you describe, possibly with a more substantial vise and two people on that rim. Make a nice loud exhaled 'banzai' as you break the thread free and shake hands after it's off. p.s. The source of your difficulty may be that BSC and Italian hub threads are similar but not the same, this from Regina: http://www.yellowjersey.org/photosfr...t/FWTHREAD.JPG -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 ** Posted from http://www.teranews.com ** |

If you've decided the freewheel is not worth saving, take it apart until the only thing left is the body and weld a block to the outer face. Let cool, grip the block is a stout vice, and remove. |

Sure you're turning the right direction? Last time I did "destructive freewheel removal" I managed with a pair of channel locks! ;-) Like Muzi said--find a circus strong man, curse! |

Use a pipe wrench and scrap the FW. You have come upon an age old failed design in bicycles, the transmission of torque through a fine pitch thread. The best you can do with that design is what you have done with anti-seize compound. That stuff contains fine metal particles that have a weaker shear strength than steel on steel. The concept is that the metal particles will not be displaced from the interface. I have had marginal luck with that but then I use a four prong freewheel remover and rotate the wheel when the remover is held in a vise. Any grease or oil in that interface will be displaced with use, so that won't help. As you see, Shimano uses a detente cover screw to retain its sprockets on freehubs. No torque is transmitted through threads. Jobst Brandt |
