Hi Mo
have a tray of old classic bits, but not identified as well as other Brit bits but cant think of any twin gears. can look at the weekend.

just one thing , is it a whine or a screach? a screach could be the bearing about to break up or spinning in the housing, a definate wine probably down to gear noise or bush play.
this is the sort of thing you need

when I first started mid eighties we had many spares stockists within 20 mile radius, British Iron, Nobby Clarke, L&D, Charlies, Chalky White, Chestermans, Michael Freeman,  Chequers and many more, all are gone now. in 50% of them its the children of the original owner not wanting to carry on the business. America (Ebay) seems the best nowadays for used parts.  I remember Fluff Brown went to America on holiday , (Fluff owned FB AJS after the factory closed.) he ended up visiting their American stockists and arranged many containers of brand new old stock to be returned. everything from cable ties to complete never raced scramblers.

not sure what you mean, the bike is a 1962 A65 or a late 1961 A10 (seperate gearbox). you could check the bushing in the gears as well. one other thing to remember, the engine is a box (or tin) the noise could be travelling around the chambers, an old mechanics trick is to put a screwdriver against various places around the engine and the handle to your ear to localise the noise origin. BUT make sure its not near moving parts!!

trying to answer after working nightshift, must read properly to avoid confusion!!

Hi Chaz,  The confusion is you put a link for A65 spitfire etc i took it as if you were saying that they were the same gearboxes as the A10.....as I say this is my first BSA so I did not know if they were or were not the same and as JulianS has said that the A65 box gears are not the same as A10..........so That is were the confusion is, to clear up anything my BSA is an 1962 A10 rocket gold star Rep so hope this is now not give anyone no more confusion lol.

ok thanks.
the confusion came as 1962 was a cross over year late to 1963 A10s and early from 1962 A65s.
I get this many times especially with Japanese bikes, dealers selling old stock off sometimes cheaper a year later than should be for that model year, especially when customers come in with their own sourced parts which I then have to order the correct part. They then get to find that the bike is a year older than they thought.

Hi all I have just picked up a complete gearbox that has been totally overhauled from an old friend that has just gone down hill with Dementia he had done three gearbox's over a year ago and he has just gone down hill over the last 6 months very quickly and he was a really great bloke with BSA`s and a great Gearbox builder as everyone I know took there gearbox to him to rebuild so I am lucky to have one he done,,,,,, cost me about 300 but that means I can take mine out and put his in and do mine when ever i want.......but I wish him well......So thanks John.

Regards Mo

And Thanks everyone for all your advice
