adjust cone and locknut on front-wheel axle
When I set out to re-fat the balls in the front-wheel
hub I noticed that the screw-nut on one side of the fork hang by just a few threads, and the reason was all the part were shifted to that side on the axle. I suppose this is simply a mistake from the previous bike owner as what I can see everything and all pieces are symmetrical (or could be) and there is no need to shift it one way or another. However when I tried to get the cone and locknut to move sideways they were stuck bad. The other pair on the other hand was very loose. Whenever I grabbed the loose pair the whole axle started to spin. I tried to hold it with a polygrip and then a pipe wrench but it still spun when I applied force to move the stuck pair of pieces on the axle. Is there a method to do this? -- underground experts united |

Do you have a cone spanner? This is a thin steel open ended spanner that fits the flats on the cone. The flats are likely 13, 14, 15 or 16mm across. The set of cone spanners I have, has a pair of 13/14mm and another pair of 15/16mm spanners. Hold the cone with the cone spanner and undo the lock nut with another open or ring spanner. (spanner == wrench). Pipe wrenches and the like are best avoided. You may grip the lock nut in the jaws of a bench mounted vice and only then need to turn the cone spanner. -- JS |

I'm not positive I'm visualizing your problem exactly, but: A handy way of turning a threaded piece that (like an axle) has no bolt head or screwdriver slot, etc. is to thread on two nuts then jam them together. You do the jamming by turning one counterclockwise, the other clockwise, until the meet and lock. Then a standard wrench will be able to twist the whole assembly. This is how studs are threaded into blind holes in engine blocks, for example. Indeed, this is how the cone is (usually) held in place on the axle. A thin lock nut is jammed against the cone on the axle, locking both in position. Cone wrenches, as described by James, fit the thin flats on the cone. Any standard wrench will fit the lock nut. To loosen the cone and lock nut, you twist the lock nut counterclockwise, the cone clockwise; i.e., opposite directions. They should separate and be loose on the axle. So, depending on the details of your situation, you may need to buy a cone wrench and use it to help separate the lock nut and cone on one side. Or perhaps less likely, you may need to jam two nuts together on the axle, then use them to twist the axle the way you need it to go. I'd bet on the former situation. -- - Frank Krygowski |

Remove the axle set and hold the center of the axle in a vise. Hold the cone with a cone wrench and unscrew the locknut. Clean all parts. Then inspect and/or clean up any thread damage before installing the axle set. And yes, it ought to be centered. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

James, Mr. Krygowski, and you all understood the situation and gave the same piece of advice what I can see. Cone wrench to hold the cone, spanner to hold the locknut, then rotate opposite directions. Yes, I did notice the jaws in the cone but my spanners were to bulky to get there if the locknut blocked one way. Otherwise they were 14 mm IIRC. -- underground experts united |

The old pipe wrenches that some people call a "monkey wrench" are good for gripping small diameters if you close the handles/levers in the jaws of a vice. The jaws are saw-tooth cut, so it matters which way you intend to turn the nut. Generally speaking the more modern "water pump pliers" are not robust enough for vice assisted gripping. |

Yes, I did notice the jaws in the cone but my spanners were to bulky to get there Lock the 2 wheel nuts together on the other end of the axle, should be plenty wide enough for the wrenches. Pass the axle up through the jaws of the vice and clamp on the flats of the first/top nut - that nut will tend to tighten by the torque you apply to unscrew the locknut on the other end, you may find the lock nut and cone stay locked together until the lock nut clears the end of the thread, but at least you don't have to worry about the strength of a slim wrench to get on the cone flats. |

adjust cone and locknut on front-wheel axle
the assemblurs assembling your bike used LOCTITE on the component's threads....avoiding liability for your injury if the components...low grade tube sure...came loose.
Often disassembly requires heat from a torch as heat cooks locktite cawsing the thread filler's crumbling into a powder that will now lubricate disassembly. Unthreading older assembly's asks for vigorous wire brushing, possibly running a razor blade point into the thread disappearing into the nut, soaking with PC blaster...Blaster is applied with an artist's paint brush (Walmart crafts) not sprayed with the can. Then heat till the nut smokes and twist off. Some assemblies are sold and oiled out that the locktite is contaminated with oil. wrenches right off. Usually on an assembly owned by another party. |

For those sorts of jobs, I use locking pliers or Vise Grips. I think Brits call them Mole Grips. -- - Frank Krygowski |
