Hello all,

The tank on my CB175K3 was leaking slightly even through the JB weld. I decided to remove it and get down to bare metal and have a good look.I found a couple of pinholes and the tank seems otherwise to be quite serviceable. The trouble is that as I chipped away at the JB weld, it dislodged the internal liner from the bottom of the tank.This liner was put on about 15 years ago and I presume was not done correctly as its about half an inch thick, and I need to get it out before I can do anything else.Does anyone have an idea as to how I can do it?


Thankyou.

Graham

Thanks for that Richard.I haven't heard of that product and I checked and they are out of stock. I have been looking on the net, and have found a product called MEK or methyl chloride which should do the job,but apparently its pretty nasty and extreme care is needed.I did try acetone but it did nothing.

Thanks Graham

Just looked on Ebay UK, and found vendors selling dichloromethane AKA methyl chloride for around 10 UKP a litre.

Considering that the Sealeater stuff cost 30 quid, seems worth a go,

I didn't take any extreme precautions when using the stuff, and I haven't died yet ….

You wouldn't want to get it in your eyes, or on the skin for very long.

I have found a place here in Sydney that sells it in one litre containers so i'll order some and give it a go. This should be the last big job to do on this bike,unfortunately I will have to repaint the tank as I have spoilt the paint somewhat, but I should be able to do that.Last week I went to a motorcycle classic restore guy and he wanted $1000 plus to fix the tank,which I am not prepared to pay,so I shall be having a go myself.It's not due for its road worthiness rego inspection until December so I have plenty of time.Once again thanks for your input,will let you know how I get on.
Regards Graham

Hello all,

Just an update on removing my fuel tank liner. I bought a litre of MEK, and it appears to be working although very slowly.i'm going to get some more and hope it speeds things up.There is a very gooey gunky mess in there.

I tried Acetone Jim, but it didn't do anything,although my liner is not Kreem.

Have you tried e-mailling the makers of JB weld? They might have a solution.

I'm wondering if warmer temps may speed up the action? Your winter temps right now may be a bit too cool.
I have heard of using hot compresses and the like to raise parts temps to speed reaction times.

No Alan, I didn't think of that,but it is certainly worth a try.

Thanks, Graham
