razorsedge Posted October 13, 2018 Share Posted October 13, 2018 If you can't grab the bolt/thread somehow..... could try using a soldering iron tip on the end of the thread. This might allow the nut to come undone by melting/releasing the grip of the nylok nut (while hot). Link to comment Share on other sites More sharing options...
Tim Z Posted October 13, 2018 Share Posted October 13, 2018 Try splitting the nut in 2 halves,using a Dremel? Fiddly but might work. Link to comment Share on other sites More sharing options...
Autosteve Posted October 13, 2018 Share Posted October 13, 2018 Hacksaw a slot in the end of the bolt you can see in the picture. Once you have a slot, small flathead screw driver in the slot and undo the nylon nut. Link to comment Share on other sites More sharing options...
Tim Z Posted October 13, 2018 Share Posted October 13, 2018 Looks like pretty tight access,hacksaw might a be a bit hard job. Dremel or if you got room small angle grinder with a 1.2mm metal cut disk,but a lot of sparx and shit. - - - Updated - - - I mean with the grinder cut the whole head off with nut and bolt,flush wit mounting plate base. But the hot sparx might do damage to playfield. I would use the grinder myself and just cover everything up well. Link to comment Share on other sites More sharing options...
Rich Posted October 13, 2018 Share Posted October 13, 2018 I recently had the exact same issue, this is how I removed it. 1. Remove all the pop bumper parts so you are left with just the plastic housing, bracket and nuts and bolts. 2. Put the assembly in a vice so that one jaw will touch the threaded end the spinning bolt and using a smaller nut than the size of the head of the one in the hex mould, or a socket will work, now close the jaws together. 3. Paying attention, as I'm sure you will, not to tighten the nut too much so that it flattens the thread, but enough to hold the bolt in place. I use aluminium guards. 4. You can now use an opened spanner to undo the nut, if the bolt still turns just tighten the vice a little more. 5. You will find that you can now undo the nut with the bolt remaining still, (keep undoing the nut until it touches the face of the jaw of the vice) enough so you can then remove the assembly from the vice and grab the head of the bolt with a spanner or pliers etc. and off comes the nut, voila! Hope this helps :) Link to comment Share on other sites More sharing options...

Hope this helps :) did you reuse the old bolt? use a new bolt? cut a groove in the old blot? Link to comment Share on other sites More sharing options...
Rich Posted October 15, 2018 Share Posted October 15, 2018 I re-used the old bolt. It's the housing that has given way, ever so slightly, but only on the right hand side. So tightening the nyloc nut didn't prove a problem. Link to comment Share on other sites More sharing options...
Autosteve Posted October 15, 2018 Share Posted October 15, 2018 When this happens you might want to make sure it is indeed an imperial Nyloc nut on the imperial bolt and not a near identical metric threaded nylok nut. They start out OK but bind after about 3-4 threads. Link to comment Share on other sites More sharing options...
