I'm looking for the rubber seal for a 1973 Yamaha CT3 Petrol (Gas) Tank.

Anyone know where I can get one? (preferrably in the UK)

The only one I can find is on the USA ebay .....and at $50 it seems expensive.

Hi Mervin,

Sorry :unsure: , I'm renovating a 1973 CT3 ...... and I'm going to need lots of help, particularly when I get around to the engine.

The part number is 308-24612-00-00.

Who are CMNSL?

consolidated motor spares Netherlands they have all the parts lists online

but i think after a quick search that part is NLA

gimme the dimensions the RD 350 cap has a very similar number but not quite the same, i have stock of them coming this week i hope i can measure one and see if they are any good too you then

Unlike other seals I've come across this has a 'U' shape profile to fit over the metal internal cap.

OD is about 54mm

ID is about 41mm

overall depth about 5mm

Thanx.

Hi Merv,

Did you manage to check your seals? :)

Hi i also have a CT1 that will be restored next year , ever thought of making a gasket.

I would have thought it very difficult to make a circular rubber gasket with a 'U' shape profile. Any ideas?

Is it u shaped because its compressed over the years or shaped like that, try looking for the other models such as AT2 AT3 CT2 DT3 RT2 RT3

as they use the same part number which should be 308-24612-00-00

Will have a look at mine when i get home tonight.

Hi, i also own a 1973 CT3, it`s a lovely little bike and my petrol cap gasket is in a pretty bad way, it leaks quite badly. Did you find anywhere to get this gasket? Any help would be gratefully accepted. ;)
