BSA B31 gearbox bearings

[KeithA]

Hello; Does any-one know the bearing type or number for BSA B31 1945 gearbox.
The one on the RHS of the mainshaft BSA Part # 65-3116.
Thanks Keith

Hi Keith,
Assuming your 45 B31 still has the original 45/6 gearbox fitted??
this type has the speedo drive on the gearbox sprocket side
The listing I have does not give a bearing number for the right hand side?? so perhaps its fitted with a bush??
The sprocket side takes a 6206 bearing pt no.29-3857

The later gearboxes take a 6207 on the sprocket side and a RLS6 in the cover

Sorry to not be able to help more

Thanks for the reply;
My gearbox is as shown on service sheet # 302.
It is very hard to see the correct part, but I have found out it is in fact a bush, and not a bearing.
Now I will have to try and find a supplier for this part.
Draganfly are out of stock.
Regards Keith
