BSA A10 Gearbox mainshft
« on: 18 September, 2017, 20:37:24 »
I have been waiting for a local racing company to produce a batch of 5 speed gearboxes but is taking forever. Having fitted an oversized needle roller, for the layshaft, that inner plate is now unusable. I have acquired another box and a needle roller layshaft from Draganfly, but my mainshaft, where it goes through the Clutch side bearing, has wear. I have read they can be hard chromed and ground to the correct diameter. I have only found 1 place in the south of England (Hounslow) that can do this. Has anyone a good recommendation of where I can go and an idea of price. Stripping engines, a rewire,12 conversion, electronic ignition new fork springs, I can do, machining is a new game to me.

The bushes in the sleeve gear are replacable, not sure why you would need to build up the shaft.
