Recalcitrant UG freehub, lube?
Folks,
The old Shimano 600 (old UG system) freehub on my road bike shows a tendency of occasionally refusing to "free-hub", wants to drive the chain. This manifests itself by occasionally driving the pedals when pushing the bike and when rolling with the pedals held still there's the very occasional THWOCK where the top of the chain dips down and the derailleur tensions up for a split second. I'd like to keep using it until the current (new) sprockets are through, then maybe buy a whole new rear wheel. Ideally a whole new titanium cyclocross bike but then my wife would read me the riot act :-) Is there a way to nurse it along? Regular chainsaw oil didn't want to do the trick. Tri-Flow maybe? Asking here before I mess something up and make it worse than it already is. -- Regards, Joerg http://www.analogconsultants.com/ |

Asking here before I mess something up and make it worse than it already is. Remove the axle set and flush the body through thoroughly with a light oil or an oily cleaner (like TriFlow). Compressed air is helpful. If it spins nicely and visible crud comes out, you're probably OK. Oil freehub body with a good machine oil, clean hub, rebuild axle assembly with new balls and fresh grease. If, after cleaning, the body spins irregularly or feels rough or catches randomly, it likely has a broken pawl which on that system I would deem fatal. Buy a modern wheel. Or at the very least salvage a less than 20 year old hub for it. New wheels are surprisingly cheap at the basic end. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

I've tried loosening the nuts to remove the axle. No luck there. Maybe the transport across an ocean many moons ago has rusted it all in place. It's unbelievable what kind of corrosion can happen even inside a sea container. The tick-tick-tick sound is regular when spinning it backwards. But it does have one tough spot per revolution where it needs to be pushed. It feels like a bearing that is giving up. -- Regards, Joerg http://www.analogconsultants.com/ |

Remove the axle and check the wheel bearings. with the axle out you can also remove the Uniglide cassette body. If it's indeed your Ubiglide body that's toast then let us know the number of cigs you had on it. I might have another Uniglide body I can send you or even a cross-over one that will take either a Uniglide cassette with a screw on high cog or a Hyperglide cassette with a screw on retainer. The crossover body has both external and internal threads. An image of the hub without the body on it will show me if what I have will fit your hub. Good luck and cheers |

BTW, you did hold the cone with a cone wrench when you tried to remove the lock nut? I only ask that because i've seen a lot of people try to remove both at the same time. when I use my cone wrench they marvel at how easy it is. cheers and good luck |

drain the hub of diesel after a 3 day soak
allow to dry careful not to cover it with soot or airborne potash drop into a can of zero weight Mobil heat to hot abt 140-150 degrees for 1 hour remove and cool install in reverse odor |
