Villiers chain ?

[iansoady]

Like "Lucas" electrics - now supplied by Wassell and originated who knows where - but not Great Charles Street. The trade names are bought up by shysters to give a veneer of respectability.

All made in China .........except Lucas trade mark is used by Bosch and all Lucas 'genuine'' parts are called 'legacy' and made in India by Bosch......Lucas is actually owned by USA conglomerate TRW Inc.

I asked the boss at my local bearing shop about the chain, and best he could come up with was O8B chain which has the right roller dia, but wider between the side plates. He said about $6.00 per foot. Some here to compare sizes.

Hi
I had the same problem and finally found a satisfying solution for me.
In many german mopeds from the 60's and 70's where chains with the dimension 1/2x 5,2x 8,5 used (sometimes 1/2x5,4x8,5). The two numbers are in millimeter.
These kind of chains are still easy available in germany, just one example:

I hope i could help you

Hi Ralf,

That's interesting. The roller diameter of 8.51mm equates to 0.335" - spot on, and the width is quite close: 5.21mm is 0.205" vs the British chain at 4.75mm (0.1875" or 3/16"). The extra 0.46mm/0.018" width is not too bad, so the chain would probably work ok?

Cheers
