SwampNut Posted June 8, 2023 Share Posted June 8, 2023 All Loctite is rated up to 300F, and there's a special one for 650. The "DB killer" insert in the KTM's aftermarket muffler likes to shake its retaining bolt loose. Life with a thumper I guess. Any opinions on which product to use?

The 650 degree stuff should be adequate, if there is no other "mechanical" means of securing the bolt. Quote Link to comment Share on other sites More sharing options...
SwampNut Posted June 8, 2023 Author Share Posted June 8, 2023 There's nothing mechanical that would work other than maybe a better lock washer than what was included. It's in a small hole with minimal access. Quote Link to comment Share on other sites More sharing options...
tomek Posted June 8, 2023 Share Posted June 8, 2023 Safety wire no? What about rivet instead of bolt? Quote Link to comment Share on other sites More sharing options...
superhawk996 Posted June 8, 2023 Share Posted June 8, 2023 A dab of .030 wire from the MP200 will secure it good & proper like 🙂 The high temp loctite should do the trick. Quote Link to comment Share on other sites More sharing options...
SwampNut Posted June 8, 2023 Author Share Posted June 8, 2023 LOL, I bet that would be great on the sheet Chinesium of the muffler. Quote Link to comment Share on other sites More sharing options...

XXitanium Posted June 9, 2023 Share Posted June 9, 2023 Could you do something with clips and springs like on racing headers? Quote Link to comment Share on other sites More sharing options...

SwampNut Posted June 9, 2023 Author Share Posted June 9, 2023 It's a tiny threaded hole behind a slightly larger access hole. The only solution is to make the fastener stay in place. My ONLY question is whether the 300 or 650 is needed. I have some basic Loctite, sounds like I should get the high heat version for this one task. 1 Quote Link to comment Share on other sites More sharing options...
rockmeupto125 Posted June 9, 2023 Share Posted June 9, 2023 I'm just getting the idea that this fix should mechanical, not chemical. Between the constant vibration and high heat, I agree with the idea of safety wire, or a large headed bolt that a spring clip large enough not to be able to turn in the muffler body... But you would have to safety wire the clip. How about earplugs? 1 Quote Link to comment Share on other sites More sharing options...

XXitanium Posted June 9, 2023 Share Posted June 9, 2023 So, not metal? Quote Link to comment Share on other sites More sharing options...
SwampNut Posted June 9, 2023 Author Share Posted June 9, 2023 Everything in there is metal. Quote Link to comment Share on other sites More sharing options...
rockmeupto125 Posted June 11, 2023 Share Posted June 11, 2023 Does the bolt go all the way through to the inner wall of the silencer? I'm just leery of using chemicals on chinesium exhaust. That just seems like high risk for tearing the tack welded nut off and not being able to remove the silencer. Quote Link to comment Share on other sites More sharing options...
XXitanium Posted June 11, 2023 Share Posted June 11, 2023 Could you just use a slightly longer bolt and back/jam two nuts into each other? Like a jam nut? I'm thinking inexpensive, something that you have in your garage. But it did spend a little time looking around for high temperature Loctite and high temperature Jam nuts: Behind door number 3 Quote Link to comment Share on other sites More sharing options...

Also, pretty sure it's not a tack welded nut, but just tapped metal. I appreciate the problem solving here, but my amount of fucks is way closer to zero, high temp Loctite it is. I'm not curious about nor considering anything other than making this bolt stay forever. 1 Quote Link to comment Share on other sites More sharing options...
