Hi, washer is felt, 0.426 od, 0.046 thick, remember that this is probably the original. spring 0.220 free. I have posted pics in the ariston gallery. You can see the components, on my deck the plain washer is next to the spring, then the pulley, felt washer, 'D' washer and finally circlip. No lubricant. Having stripped it for the pics and reassembled it's fine, no assistance has ever been required for the turntable to start.
