G'day Graham,
Any of the major belt suppliers should be able to help. By that I don't mean the local bearing/industrial supply house. Go back to who supplies them, the belt specialists. I had to do this to source a belt for the drive to my Kubota alternator. When I contacted them they thought that the pulleys I was using were a little on the small size and suggested that I use multi rib belt. When I said that I wanted a little slip in the belt they told me to turn up some flat pulleys and turn the multi rib over. I had already turned up the V pulleys so maybe next time I will turn up some flat pulleys and use an upside down multi rib belt.

Hi Graham,

If you are looking for a online supplier rather than a local supplier try Bearing boys.

http://www.bearingboys.co.uk/Vee_&_Wedge_Belts-1025-c

They have a good web site for all lengths of belts. When I needed non standard belts for my lathe, I measured the length / cross section and ordered from them. Quick delivery and cheap. Its also an interesting site for other products.

p.s. I have no connection to this company apart from been a satisfied customer.

Cheers,
Simon.

Hi Graham, I'm hoping you find someone as my Prince has approx the same size belt. Although I do have a spare inthe paste i've bought mine from Fenner Transmissions but it seems they've been taken over by Dunlop and no longer have trade outlets. As Simon says iv'e just had a look at the Bearingboys site and they do have someone you can talk to if needed. Good luck and let me know if you find a supplier. John

Crikey - thanks for all the replies everyone.

I'd forgotten about the local one to me that Manxnortonman pointed out, and in hindsight, I should have tried them first.

However, in the meantime, I contacted J&M Belts as suggested by Roy The Mechanic, and they're going to sent me one for £5 all in. In the post today, and all I have to do is send them a cheque once I receive it!

Thanks everyone. Maybe now I can go out on the Meteor with breaking down!

Referencing ogrilp400's ideas earlier. Those in the know will be aware that Dick Sherwin and I provide a car alternator kit which uses a polyvee belt. To avoid alignment problems with the belt the first prototype I made used a non-grooved pulley at the bottom on the dynamo replacement and a grooved one on the alternator. The idea was taken from Flymo lawn mowers who use a similar system. The difference was that Flymo have grooves in their smaller, driving pulley and a smooth, larger driven pulley. Mine slipped badly as we use a larger driving pulley when compared with the driven pulley to allow the alternator to run at about double the engine speed. I had to resort to using grooved pulleys both top and bottom. Why did we use the multi ribbed polyvee belts? Well they are designed to go round small radii, which is why we did not go for normal 'V' belts and they do allow more slip than a normal toothed belt, use of which has been found to have a short life due to the nature of the Vincent dynamo drive (on twins). I do not know what gear ratios are intended but turning a multi vee belt over and running on the flat side sounds like a recipe for disaster.:)
