    Stuck Axle Nut on rear....singlespeed

    hello!

    i did a cursory search and didn' t really see anything....hopefully someone can help....sorry in advance if this is covered somewhere and i suck at searching lol....


    anyway,

    i have a singlespeed rear hub on a track frame.


    was going to remove the back wheel, but ran into a problem:
    when trying to remove the two axle nuts with my 2 15mm wrenches, one axle nut came off fine, but the other is seriously stuck.

    after a little wd40 and trying to muscle it off, i notice the outside hexagon of the axle nut is starting to get stripped and rounded! i of course stopped immediately, but im having the hardest time trying to figure out how to remove it without further stripping the outside.


    anyone have any advice? it would be greatly appreciated!

    You might want to try a product more suitable to freeing threaded fasteners, like Liquid Wrench or PB Blaster. I've used the former with great success, and many on BF swear by the latter.

    To prevent this in the future, grease the threads before assembling.

    i am going to go get some liquid wrench and try it out.

    your second advice about greasing the threads is something i always do but i think i got too excited when i got my wheelset in the mail and forgot to do it in my excitement @_@ (doh)

    thanks!

    Now that the nut is off the other side, you're going to have to stop the axle from turning in order to get the second nut off, right? I'd put the other nut back on and then once you've soaked the stuck side with PB Blaster or Liquid Wrench or whatever, put the wrench on it and instead of trying to turn it with your hand, wack it with a big hammer (in the direction it spins off). Sometimes the "shock" of the hammer strike will loosen bolts more easily than just pushing on them. Or get another wrench and situate it on the 15mm wrench such that it makes one much longer lever for you to pry on so that you're leverage is greatly increased (or slip a big pipe or something over the end of the wrench to accomplish the same thing).

    Unless it's some sort of fancy axle nut, I wouldn't worry about rounding it off since any bike shop or hardware store will have a replacement for you. So if it gets so rounded off you have to use vice grips to get it off, don't sweat it.

    RE tighten the nut that came off OK, greasing the threads with anti-seize , first ,
    and then loosen the one that was resisting coming loose, having nut A in place, again, so axle wont rotate.
    grease the threads with anti sieze on that one, B, snug it back on, and the first one will loosen again.

    15mm 6 point box end wrench is Ideal , snap-on wrenches are the Best,

    well, its off!!!

    i believe in my excitement of getting my new wheelset in the mail i accidentally forgot to grease the threads when i got too eager beaver to put it on the frame....lesson learned!


    what ended up working for me was this: (in case this happens to other newbs like me)

    1) got some PB blaster....applied liberally. waited a few minutes.
    2) didn't use vice grips, but used a 15 mm hex wrench....as opposed to the park tool 15 mm wrench that is only two prongs...

    This....


    instead of this...


    the later was just digging into the outside hexagon and rounding the edges.

    i wasn't really having problems with the axle spinning, it was pretty stationary. i dunno if this matters but it was a coaster brake hub....

    anywho, thanks for the responses! remember fellow newbs, grease your threads! case closed lol

    SCW is a cone wrench, even a pedal wrench would be an improvement .

    +1 Do not use a cone wrench to remove an axle nut. A closed end wrench, like you used, is the weapon of choice.

    Cone wrenches are strictly for cones which are hardened and have narrow slots limiting the options. Otherwise always, use box wrenches, or broad open end wrenches to work on nuts. The thin cone wenches will cut into anything not super hard.

    the open end of a wrench is not really suitable for breaking a fastener loose, on a tough nut the open end can spread. use the box end if you can to break it loose

    A few generalizations from this little adventure:

    A six-point socket would have been another good first choice on that nut, esp. since six-point box wrenches are hard to come by.

    WD40 is NOT a penetrant. It's a pretty lame lubricant.

    Threads get stripped; heads/flats get rounded. When they do, there are a number of extractor socket products that "bite" into what's left of the fastener. Craftsman "Bolt-out", Irwin, Stanley, shoot even Harbor Freight makes them. They do work; fortunately, you didn't have to find this out.
