Joeboy, yep I could use them again but the plank that installed these bolts cross threaded an M10 x 1.25 nut on a 1.5 bolt so they have to come out
Right I have just spent 3 hours this afternoon trying what I could.
Started on the right bolt (worst one) ground the burred bit of so I could fit a nut back on it.
And also drilled a couple of holes in the ally mounting lug so I could get WD40 to, hopefully, penetrate the hidden part of the bolt.
Tried the 2 nut approach but to no avail, wouldn't lock off, just screwed the thread off.........Result, No movement
Tried the heat then soak in wd40 then hit said nuts with lump hammer and drift........Result, No movement
Tried welding nuts on, two pronged attack, the heat would be better than my blowtorch, and It will overcome the thread issue above, .......Result, No movement
So,I cut the bolt off flush with a grinder and resigned myself to the long task of drilling it out.
Just about room for the chuck to clear the casing, slightly off centre but managed to get a 9mm hole that removed one side of the bolt down to 3/4 its depth and twatted it with a drift,whilst applying heat, as this way its effectively being pulled out rather than pushed through the mounting....Result, Movement, just a little, but movement none the less
Success
Not looking forward to doing the left hand side but it came out with just a swift clout and some heat, as I said the other one was worse.
So now I can replace all the crappy mounting bolts with nice new shiny stainless ones
Oh and I found the end of my allen key, it was 15 feet away from where I was working on the driveway on the garden, the other side of my car!?!?!?
