Awww... crap. How to fix this?

[Dammit!]

Any brainstormers wanna help me out with a way to fix these things so they don't spin? It's not leaking (amazingly) but I had a hell of a time getting that top one off.

[wanta250r]

Maybe you can squirt some plastic/JB Weld around it?

[Dammit!]

JB Weld was my first thought. I know it will bond to the metal but not sure about the plastic. I may need to (carefully) cut some notches in the plastic so it has something to grab on to.

try this... get an old spoon or butterknife or something and a propane torch, heat it (the tool you decide to use, not the tank!!! hehe) until it gets hot enough to melt the plastic and push the melted plastic back in around the insert, you may even need to find an old peice of plastic to melt for a little bit of extra material, it may turn black, but if you take your time and go slow it wont. (I have a bunch of old busted up honda plastics for just this reason)
sand it smooth with some sand paper and buff with some fine steel wool and youre done. HH

hey Doug, just Apoxi it.... get your self some industrial grade apoxi, and apply it till you fill the holes around the metal and then your good!!!

Would epoxy be better than JB Weld?

I love JB Weld. I've fixed all kinds of crap with it that you wouldn't expect it to work on.

[RideRed250R]

epoxy (sorry for my HORRIBLE spelling) would work better on that, jb weld, is Metal to metal, or patching metal, epoxy is more of a filler material...

I had a similar problem with my tecate tank. You were lucky to get the bolt out.

In my case i spun the bolt and nut with a drill until they both seperated from the plastic, they got hot and just pulled out. Then i soldered on some tabs "little wings" to the nut.

Then I heated the nut "complete with tabs" and pushed the nut back into the plastic. put some epoxy in the gaps around the nut. No more problems!

I used a super strong super glue and it works great. You could also use a plastic welder and fill in the back area with extra plastic.

get some good epoxy

[Erics350x]

Go to a auto parts store. they carry a product for fixing rubber and plastic bumpers, very strong stuff. i know napa has it.

And once you get the nuts fixed back into the tank, use a bit of Never-Sieze on the threads to keep it from ever happening again.

[Dammit!]

I just picked up some stuff called PC7. I went to a auto body paint/supplies store for some of that epoxy and the guy told me to get this stuff instead because nothing else will bond with polypropelene (sp?). Anybody ever used it before?

[Dammit!]

Well so far I'm not impressed with this PC7 stuff. I used it on a junk tank as a test. Still soft after a few hours. Scraps right off the plastic too. Says it cures overnight so we'll see I guess. JB Weld would be hard as a rock by now.

[BigGreenMachine]

That PC7 stuff blows! I have a tube of it and its absolutely useless.
