Oil tank internal pipe missing

Good afternoon,

Having cleaned up my WM20 oil tank ready for painting, and looking through the maintenance manual, I think that the internal return pipe may be missing! Has anyone successfully managed to re-attach a section of pipe within the tank? I would assume it woukd have been welded/brazed to the union before it was secured? I have read many of you don't worry about a return filter, so the correct method of securing it wouldn't matter so much. But I will certainly need a way of checking the return flow of oil.

Would anyone have a picture of inside an empty tank they wouldn't mind posting on the forum please?

Many thanks

Adam

Hello Adam,

I would think it wouldn't be too hard to slide a thinner diameter pipe inside the existing spout on the outside of the tank, and then solder it in position. Just clean everything well first or the solder won't stick. The oil pipe has only to rise above the level of oil in the tank, after all. I can't post a picture of the inside of my spare oil tank I'm afraid. I've never managed to master the technique for getting them on here! If you want pictures, send me an email and I'll wing some back to you.

Failing that, I have a spare oil tank.

Allan,

Thank you for the reply! Yes I will see about getting some of the right diameter steel pipe, can it up and see if I can get some silver solder to stick.

Do you know if the pipe is full diameter where it exits or is it similar to other marks where they are crimped or capped with a smaller bore side exit hole?

Many thanks

Adam

This might help. Copper pipe would be easier. Ron

Re: Oil tank internal pipe missing

Thank you Ron, agreed, copper will be tried first! Is that a baffle plate in the tank or a bracket?

Thank you for the assistance!

I guess it's a shelve for the filter to sit on. I would look in my oil tank but it's full of oil. Ron

This one is pretty manky inside, but you can see there is a circular seat for the filter to sit on and the top of the pipe is blanked off, presumaby there is a hole somewhere on the side?

Yes Rob, you can see the hole in the drawing I posted. Ron

Re: Oil tank internal pipe missing

Excellent replies thank you all for the pictures and information.

I think I have what I need to repair the tank now!

Many thanks

Re: Oil tank internal pipe missing

I'd cut it open to do the repair.
Also I'd be sure there were no other issues.

Better safe than sorry.

Re: Oil tank internal pipe missing

It might be easier just to get another tank?

Re: Oil tank internal pipe missing

It doesn't seem that long ago that there were several at every jumble for £25 a time, but things have changed, still a few on ebay for £75 plus postage but it depends on how much you value your time I suppose?

Re: Oil tank internal pipe missing

I just missed out on a reasonably priced tank last week (£35), by a matter of minutes on ebay sadly.

I have some 5/16 copper pipe and will give it a go with some silver solder, I don't mind spending time fixing things, and it would be a shame to see this one on the scrap heap. If it doesn't work I will keep my eye out for one that's not too expensive. I have plenty more to do on the bike in the mean time.

Thanks for all the comments

Re: Oil tank internal pipe missing

I have a tank that is complete internally and in usable condition but will require some filler for a few dents before painting....You can have it as a freebie if you pay the postage on it (I don't know where you are but UK only I'm afraid)...Contact me off forum if your repair doesn't work out....Ian

I know strange things happen to these machines over the years but this is a bit weird. Do you have any idea as to how the pipe came to be missing?

Re: Oil tank internal pipe missing

I bought a very nice tank before realising later the oil pipe was missing...Fortunately the dealer took it back and refunded my money...He hadn't noticed either!!...I don't think it's a common problem, in 50 years I only know of these two...Ian

Re: Oil tank internal pipe missing

I have one oil tank has the internal return pipe missing but is pretty much perfect otherwise - that still makes a very small failure rate. :wink:

Re: Oil tank internal pipe missing

They could have been used like this one as a temporary petrol tank?

Re: Oil tank internal pipe missing

Interestingly there doesn't seem to be any sign of the internal bracket having ever been fitted, but you can see where there may have been a pipe attached to the inside.
