merckx Posted October 9, 2006 Share Posted October 9, 2006 You could try tightening them all. Link to comment Share on other sites More sharing options...
bromy Posted October 9, 2006 Share Posted October 9, 2006 You had all that lot in pieces the other week did you not:no: try some shake proof washers or depending how hot it gets nyloc nuts Link to comment Share on other sites More sharing options...
keron Posted October 9, 2006 Share Posted October 9, 2006 You could try tightening them all. you beat me to it..... Seriously though, as brom said really....unusual is it not? have you checked the exhaust rubbers to make sure they are on/in place as the movement in the system could perhaps loosen them??

JohnA Posted October 9, 2006 Share Posted October 9, 2006 It's driving you nuts, isn't it? Link to comment Share on other sites More sharing options...
Daston Posted October 9, 2006 Author Share Posted October 9, 2006 yeah tightened them all up before we left to go to santa pod by the time I got back they were almost completly undone! I will pick some nyloc nuts up Link to comment Share on other sites More sharing options...
TLicense Posted October 9, 2006 Share Posted October 9, 2006 I don't think nylocks will work under that kind of temperature. You need some Nordlock washers. They physically can not vibrate loose.... http://www.nordlock.com/ Link to comment Share on other sites More sharing options...
Daston Posted October 9, 2006 Author Share Posted October 9, 2006 cool cheers for the link Link to comment Share on other sites More sharing options...
JohnA Posted October 10, 2006 Share Posted October 10, 2006 If the threads are clean and straight and new nuts are tightened properly and they keep coming loose, then I'd be inclined to find out *why*. Maybe there are vibrations that shouldn't be there. Focusing on the symptoms instead of the cause could end you up with a cracked pipe. Link to comment Share on other sites More sharing options...
Kranz Posted October 10, 2006 Share Posted October 10, 2006 Or instead of Nylocs get some K nuts. They're same as nylocs but with a metal locking part so aren't affected by temperature. Link to comment Share on other sites More sharing options...
