Stu Posted January 31, 2021 Share Posted January 31, 2021 As I say if they are bolts then I would replace all with a stud then brass nuts You don't have to use specific studs you can make them out of threaded bar or stainless bolts you may already have and cut the head off and file the edges The idea being that in the future the studs will always stay put and the nuts would come off easier and they are also easier to break off if they seize 1 Quote Link to comment Share on other sites More sharing options...

Ian Frog Posted January 31, 2021 Share Posted January 31, 2021 I always used the 2 nut method till I got the studs with the allen headed hole, in fact the first time I didn`t realise they had the thing lol fitted 2 studs before I twigged. Not sure if they would be easy to remove that way but I did liberally coat with Copaslip as I always do. Cheers Ian 1 Quote Link to comment Share on other sites More sharing options...

fifthwheel Posted January 31, 2021 Share Posted January 31, 2021 I hope you get the studs out, if you struggle and want me to post my tried and tested method using a welder (mig preferably) I will, John. 1 Quote Link to comment Share on other sites More sharing options...

Yes as the head is standard and the new pipe is made to suit the head. Cheers Ian 2 Quote Link to comment Share on other sites More sharing options...
WD-40 Posted January 31, 2021 Share Posted January 31, 2021 What's in it is M6 studs and nuts. That is part of the reason they snap. They should have used M8.

jedibiker Posted February 1, 2021 Author Share Posted February 1, 2021 Managed to work off the left side bolt easy, so now I know it is a bolt, although odd looking like a cap. Tried a middle pipe bolt and it snapped with hardly any force. But, it looks like even if they snap, i can then get something onto the stud and get them out. Mole grips or weld as said above. Bit of progress I guess. 1 Quote Link to comment Share on other sites More sharing options...

Bender Posted February 1, 2021 Share Posted February 1, 2021 If your ok with welding, get a nut to fit over stud and weld it on, heat stud and nut a few times and see if you can rock it back and forth to get it moving. 2 Quote Link to comment Share on other sites More sharing options...
Mississippi Bullfrog Posted February 2, 2021 Share Posted February 2, 2021 Did you follow @skyrider advice and soak them in PlusGas. Having dismantled several 1970's cars I know it is good at freeing seized nuts and bolts. On the few occasions it didn't work first time I used a second dose followed by a squirt of WD40. The WD40 being a dispersant helps drive the PlusGas into the seized joint. I only ever had one time that didn't work. As @Bender says, don't just move the nut in one direction, very small amounts of movement either way will loosen better. Quote Link to comment Share on other sites More sharing options...
