|   Loctite question | GirchyGirchy
Jan 22, 2003 2:24 PM | | I will soon be putting a disc on the front, and have decided to unscrew the brake bosses so they're not sticking out. I bought some set screws that fit in there, but I need them to stay in place, so I thought of Loctite. I'm wondering, what colour or value would work for this? I was thinking 222 or 243 would be the best.
Since we're on the subject, what about other threads, such as the V-brake bolts and other assorted bolts and screws? Are there two or three values of Loctite that would work well all over the bike? Thanks for any help!

Jan 22, 2003 2:35 PM | | Not sure of the actual values but, as a mechanic, have used the blue loctite in a number of situations. Never fails and is not permanent.
I like to use it most on my wheel builds. Wheels are bomb proof.
I say use it on the brake bosses but not too liberally. As for other areas of the bike (where, specifically and why??), I probably would be a bit reluctant to recommend its use but that depends on the situation.
Hope that helps. |

Jan 22, 2003 10:04 PM | | I've never needed to use anything other then anti-sieze on my spoke threads and I have no love for anyone who uses any threadlocker on a spoke thread.....it tears the heck out of the nipple and is almost as bad as trying to fix a wheel run over by an M1A1 (seen one of those....very not pretty!) |

The threadlock is not permanent and I use it very conservatively.
Tears the heck out of the nipple??? Not sure I understand. |

Jan 22, 2003 2:37 PM | | the label. You don't want a permanent bond. Just something that acts as an interference fit. I think I've got the blue downstairs and I believe it's the same color on the bolts on my bike that use it.
Personally I just used expandable foam earplugs to fill the holes. |

Jan 22, 2003 5:08 PM | | they're a structural part of some forks (Marzocchi definitely). Marzocchi has an official replacement part just for this purpose if you don't want the bosses sticking out. If the brake boss bolt is way bigger than it should be and it has blue loctite all over it you can safely assume it's structural.
Just a heads up. |

Jan 22, 2003 5:34 PM | | Loctite "242" is the grade you want, it's the medium strength blue stuff. Use it on anything on the bike...but NOT on your spoke nipples. I tried that once and had a majior headache come truing time. If a wheel is built properly you shouldn't have to glue it together. |
| loctite = spokeprep ??? | bn
Jan 22, 2003 6:12 PM | | not |
| loctite = spokeprep ??? | racer99
Jan 22, 2003 8:01 PM | | Just don't use red locktite. It requires heat for disassembly. Use blue. |
| Loctite as Spoke prep=CRAZY GLUE... | Dirt Pilot
Jan 23, 2003 3:56 AM | | ...I used green Loctite 290 (ligher duty then blue 242) and had nothing but trouble with that wheelset from the first time I TRIED to true them up. I was rounding off and cracking nipples (alloy) like crazy and ended up rebuilding those wheels 6mo after I first built them.
Wheelsmith makes spoke-prep that they claim has a thread locking agent as well as a lube but it's pricy, anyway I'd never us a thread locking agent again after my experience with the green Loctite.
Use anti-seizing compound on your spokes and a little grease on the nipple seats of the rim. Proper spoke tension is what holds a wheel together. If you need to glue a wheel together, it ain't built right! |

| Blue is the right stuff | GlowBoy
Jan 23, 2003 12:30 PM | | for an incredible range of projects. Faucet handles in the house or Thule rack attachments that won't stay screwed down are some of my favorite uses.
That said, I've never needed it for anything on a bike, except maybe cheap cargo rack bolts. Most decent quality bike parts should stay tight. Loctite is good insurance for critical parts, or for parts that seem to rattle loose even after you're sure you've tightened them properly, but as Calvin Jones said it's not a substitute.
