I think it came from Waldridge several years ago. I can check, I guess.

So I picked up some well nuts, I think they are shorter than the ones Old Britts uses. I had tried mocking them up at one point but it didn't seem to work, then I tried again using a spacer and I think I have it now. Before I didn't have the nut far enough up, but now the spacer works. The spacer will be replaced with rubber washers and I think it will all go together.




And video of me picking up the tank by one of the nuts. It's REALLY secure.

Hi Dave:
It is the same way my bartell tank is mounted.They send a rubber plug with a brass insert molded in.I made up a stud 3" long and threaded it in to the full length of the plug. I then used a washer and nut and tightened up the nut till the rubber plug expanded .You have to hold the stud well you tighten up the nut.It only expands a small amount.I had enough of the stud left to go through 4-5 norton rubber washers and go through the frame mount and put a washer and nut on.I opened up the first 3 washers so the locking nut goes through.That way the washers sit flush against the tank mount

Any chance of a picture? I think how you describe is what I'm trying to accomplish. Do you remember if the well nut (what you call rubber plug) you have is really long? Mine's only about a inch tall.

I believe the tank was originally from Bartell.

Funny thing is the fuel tap areas aren't drilled through just tapped.

It looks like the standard P11, Matchless style mount. Rubber with through bolt, tighten mount nut and it expands the rubber to tighten in the tank holes. I don't have any pictures unfortunately.

Just imagine the thick metal washers are going to be rubber ones. I may need more thickness here, but I'll know more when I fit it.



Anyways, something like this.

Hi Dave:
You can use screws like the last post pic shows.My rubbers are 1" long with a brass insert.I just used a stud and nut to expand the rubber. I made the stud setup so the spacer rubbers and rubber inserts would stay in place when I took the tank off,just like the stock setup.Either way will work.

Dave, what about a bar end addaptor, you can get them cheaply for push bikes. Or if you want to make your own, a rubber bush that fits the hole in the tank neatly, and fashion up a stud with a slow taper, so that as you tighten from below throught the mountthe taper is drawn into the bush thereby expanding it.

I'm pretty sure that's what a well nut is. Thanks for the suggestion!

Got the rubbers from Old Britts today. Now I need longer bolts, but that's ok. I think the stock setup is two washers on either side of the bracket.


Under the tank you can see the pad. This is the stock pad 06-2567 and look like it will work perfectly.

Those are the right bits. I use them on an aluminium fastback tank.
To remove the tank I loosen the bushings and lift the tank off off them leaving all the spacers and bolts in place, use the standard large rubber washers to get the tank to the right height. I did find a problem with the bushings getting stuck after fitting dry so I give an occasional thin smear of silicon grease. They work very well.

Yeah, I'm noticing them sticking already. I'll hit them with the grease tomorrow.


Tank to top triple clamp was TIGHT. I tried two on top, but had to go with one. With everything tightened down there is just a little clearance. I'll have to keep an eye on it.

A note for anyone interested, the "standard" length well-nuts that I'm using are turning out to not be long enough. The tank seems to come loose a little too easily when the bike is running. I'm looking for a source for longer well-nuts. They are out there but not easy to procure, yet... Stay tuned.

Dave, Dave, Dave, Dave, Dave.

Use P-11, N15, or g15 tank mounts.

Do you have the dimensions of those mounts?
