Stuck bolt in tank

[fester]

Hi after trying to remove my radiator plastics I seem to have a seized bolt in one of the brass inserts in the tank. I have managed to get the plastic off but the and insert ear just spinning now. I have tried a few things but they are both just spinning . It ( the insert) still feels sort of tight but still spins. Hopefully someone here has had experience dealing with this and could help.

Cheers Rohan

I've got the same problem! And new plastics to put on too. It just spins and spins! Any ideas would be much appreciated. Its the same on both sides of my tank...

You need to try and get the brass out and use a strong glue to put it back in, and make sure you dont over tighten and put some grease in the thread.

exact same thing happened to me on my yz. what you have to do is put an electric drill on the bolt and spin it fast to heat the plastic up. then use vicegrips and pull it out. then glue back in.

Ok! Thanks for the info!

Yea that is gay and is much more likely to happen in the summer. I use anti-seze on all my bolts. Yet to have a problem on my current bike. Good luck. I fixed my mates but expoxying it back in with really good expoxy.

I managed to get it out by spinning the whole thing with a drill and pulling it up enough to get some vice grips under it. The previous owner had made a bit of a mess around it with a hacksaw so keeping an eye out for another tank. Any idea on cost???

shouldn't really matter should it? the yz shroud covers it so you cant see the repairs. new tanks are expensive, not worth it imo unless you want a bigger one.

Just a thought: I fixed a big crack on my cars windshield washer tank with a soldering iron and used plastic chunks cut from brackets (from same tank) as filler rod.

Was quite surprised that it worked, but it was similar to welding/soldering steel. If you get too hot it fizzes like overheated metal too. Repair area needed to be very clean, any trace of dirt was a problem. Used white spirit.

You'd have to use same tank plastic for filler as this'll be different to other plastic types. Just looking at my bikes tank, maybe you could cut some strips off a chunky rear part where it sits on frame. Maybe cut some hacksaw grooves (or something like that) in the brass insert you'd have a solid repair?

Be super careful about fuel fumes if you try it though, empty tank and flush with soapy water.

cut the bolt head off, when you cut it with a grinder it will get hot, let it cool and the brass insert will be welded back in, use vice grips to get the thred out, then forever use inti seize on them.

My mate drilled the head off the bolt then I put anti shock super glue on the insert and was able to undo the rest of it with vice grips. I don't know if this was the best idea but I was busy marking the cams while he was looking at it. One of those times when you're trying to hint subtly that you want them to not touch anything as they could break something and piss you off big time.

using a cut of disk would of been the best option and taking time not to allow the brass to heat up replace the brass insert with a 2 piece one

hahahaha....and here was me thnkin, what the hell would you want to stick a bolt in your tank for? It would just rattle around in there all day long!
Might need a wee lie down about now...
