Cracked fuel tank!!!
Permalink  
 


Hi Ryan

I think you guys in Oz seem to have a bit more trouble with the tank-tree interface than we do in the UK! 

We have sold quite a few tanks to Australia but the shipping is extortionate. A second-hand tank including shipping would be over £200 no

Repairing a damaged or cracked plastic fuel, gas or petrol tank
Permalink  
 


Hey guys, I have a ttr-250 and have noticed that my fuel tank has a crack in the top of it after it started leaking when I filled her up. The crack is about 7cm long I would say but it's only a little hairline crack. I have tried the solder iron trick but I can still see the crack, I'm not even sure if this theory works or if I haven't done it properly. Reason being I was quoted $800 dollars for a new tank and I thought that was abit rich. Please if anyone has any ideas or any cheap tanks they know of, help would be much appreciated, Cheers

Have a look around for plastic welders in your area, check the Yellow pages etc... in the auto section where people repair plastic bumper bars etc...

A place to start at least, also check the local bike wreckers

Good luck

Thanks Steve, yea that's the other trouble I've had, I'm based in Adelaide, South Australia, and I've phoned many companies about welding my tank. One placed agreed to do it them I phoned them today to find out that they couldn't. Ive tried wreckers also and they just tell me how hard it's going to be for me to find one
Thanks for the reply Steve I appreciate it.

Hey chester,

                    You could check out this thread maybe it helps http://www.ehow.com/how_4690973_repair-plastic-fuel-tank.html

I have repaired tanks before using Selleys kneed-it before and had no problems. Check out this thread if that last one does'nt help http://www.selleys.com.au/putty/epoxy/knead-it-multi-purpose#information

Failing that you will have to get it plastic welded cry

Too easy man,

                     If your going down the Selleys kneed-it road just make sure you roughen up the surface with some 400-600 grit sandpaper so it sticks and clean surface is always good  http://www.selleys.com.au/putty/epoxy/knead-it-multi-purpose#information

Put two layers one small then one over the top of it then you can sand,file,drill,cut or do want you want with it.

Interesting story....

Once i was up in the middle of nowhere visiting a friend of mine and it was a rough road. It turned out rougher than i thought and a big rock bashed a hole in the sump of my Holden kingswood. I had some Steel kneed-it handy as always in the glovebox,so i waited for a bit for the oil to drain out.After some time it was still draining and it was getting dark.

I had no torch with me and was a long way away from the nearest house so i had to move quick.

I decided to wipe it down with petrol and a rag then jam what i could into the gaping hole still pouring oil.

After some effort of trying not to mix too much oil with the kneed-it i finally sealed it.

I still was'nt sure because alot of oil had mixed with the kneed-it

I then scrached it up with a rock wiped it clean again with the petrol and rag and put another big ''wadd'' of it on.

To my suprize it worked better than i thought and lasted me another four years like that.

When i sold the car ''just about a wreck'' it was still sealed and as far as i know it is still sealed today.

Amazing stuff biggrin

Here are some other fixes i  have done with no trouble at all...

Side crankcase covers ''even 35mm holes'' Steel kneed-it

Plastic torch light cover multi-purpose Kneed-it

Car Body repairs Steel kneed-it

Copper fittings Copper kneed-it

The other fixes are boring and you'd get the point by now

It has'nt failed for me yet except for my carby support mount but i think that was asking too much biggrin see here http://ttr250.activeboard.com/t50560400/repairing-a-broken-carburetor/

Don't like to bring up the past but it would be good to know what method was used???

Did the kneed-it work or plastic weld???

Gas tank repair
Permalink  
 


Hi guys 

 

I have a nice crack in my 99 ttr250 blue gas tank, i put a think line of fiberglass resin and hardner over it and it seems to work fine for now, no leaks. But was woundering if any of you have any other suggestions? What im thinking is to just fiberglass it with the fiberglass resin and hardner and paint it. My thinking is that since the resin worked fine by its self, then doing fiberglass as it should be done should work...right? LOL

is is so not self and wavy no, but, I have a large industrial mower and split the plastic tank on a barbed wire fence disbelief. we fixed it by draining the tank, then melting the plastic back together with a lighterbiggrin the repair was a temp fix to get us back to the vehicle, that was 3 years ago, but so dangerous, biggrin

This link - CLICKY LINKY - takes you to an article by wikiHow regarding tank repairs.

It may contain the answer you're after, Marshall. confuse

On a personal note, I have successfully repaired many of my "plastic accidents" (NOT petrol tank) using my electric soldering iron. smile

What a great tip, I noticed a massive (275mm) crack/split in my tank which leaked fuel when full yesterday and thought new tank or plastic weld job needed for sure. However after reading this tip I have just bought a tube and carried out the following repair (still to sand and repaint) but it's not leaking yet, will let you know if it holds up after a couple of tough rides.

Once again, thanks Jarrah.

No problems Michael thumbsup.gif

If that fails (it shouldn't), you can use a soldering iron and some blue plastic to melt onto it. This worked a treat on my old WR400 plastic tank (now replaced). First run the soldering iron along the crack to seal it, then fill in the crack with more plastic. I have also used this method on many other plastic things and it is stronger than gluing.

Enjoy!

Jarrah

2002 TTR250 Fuel tank
Permalink  
 


I bought a TTR250 on 3 days ago and what do you know as soon as my father touches it, he pierces the fuel tank loading it onto the truck. Cant find any original fuel tanks anywhere and I really do not know where else to look, whether buying the same one or whatever. I am honestly very new to bikes so I have no idea what to do. smilesmile

I managed to find a company around the corner that repairs plastics

 

Left it with them for the day

showed me the pressure testing and it was all sweet

another $80 down the drain but much better than finding any other alternatives

 

And thank you for the welcomes, much appreciated smilesmile

Fuel tank split...help.advice req
Permalink  
 


Hi all. Was out today on some local tracks andon the way home I pulled into see a friend on the way back. As i stopped there was fuel gushing out of the bottom of the tank onto the exhaust and engine. Stood there waiting for it to ignite but luckily it didnt. After it stopped i went and checked it out and it appears that some one had plugged a hole up with jb weld or similar. It must have rattled loose or split on the trail..

My question is that there is a fuel tank for sale on totally ttr web site but the photos look like someone has welded a round patch on the bottom. Do these tank go there frequently or is it a factory fitted patch.Am i better to save up for a plastic tank? Any thoughts or advice greatly appreciated. Regards wayne.

I think you will find that the metal tanks, over a lot of time, have a problem where they are rubbed with the saddle and at times rust and leak. bleh

Repairs with JB have often been shown to work, but must be really regarded as temporary.   hmm

Welding a metal tank is the really sure way to repair - but is dangerous for the amateur repairer. Best entrusted to pros. who know that petrol, fumes and heat are together lethal.

Totaly TTR has a used, refurbished steel tank currently HERE

A much safer, neater and cost effective (£40 plus post) repair.

I have used Plastic Paddings Leak Fix to repair OE tanks in the past and it has provided a long-lasting solution to leaks.

See http://ttr250.activeboard.com/t44176501/restoring-oe-petrol-tanks/

It is certainly worth a try on your tank before you bin or replace it.
