How does this gas cap come apart?

[Dwight Romberger]

Hi all,

Does anyone know how I can take apart this gas cap?

I want to replace the part that goes in the tank with a larger one.

I don't see any fasteners and throwing it against the wall doesn't work!

Thanks for the help.

Looks like a press fit to me. The locking part is probably riveted to the inner ring and the unit pressed into the chrome cap.

If it is pressed together, how might I pull it apart?

Unless there is a snap ring on the inside of the cap by the lip, then it is machine folded and pressed on. Trying to get it off manually will mangle it for sure. A lathe in a machine shop may be able to cut the inner stuff off. Then you will have a $100 cap at least.

Why not simply tell us which cap with the dimension of the opening you are needing?

You were right. It was pressed in there. A little pushing and pulling and judicious tapping and it came off.

Thanks.

I am trying to make two 3 1/2" matching caps that look like the originals. One for the radiator and one for the gas tank. I have an original one for the gas tank, but it needs to be rechromed. Too expensive right now.

These are new chrome. The pair will cost me about $80 plus a small amount of blood and band-aids.

Thanks again guys for your help.
