Hello, I have a 1955 model 19s Norton. This has the rear wheel fastened on to the sprocket-ed brake drum with three studs and a spindle through the axle. The brake drum and final drive chain stops in place on a stub axle. Now i cannot get get the stub axle tight enough to stop there being movement when the wheel is in place. You know hold the wheel top and bottom from the side and pull and push. The manual and spares list show no washers or spacers between the brake drum and stub axle but it feels as though there should be, is there something missing on the brake plate side that would make things tighter? Anyone got any ideas.
