You probably know this but, the original ML8 was painted yellow, then silver, and finally green. I have a parts diagram if you're interested. Send me your email address if you want a scan of it. My old ML8 had no belt when I bought it, so rather than try to remove the spindle,I bought a plastic link belt which has been in place now for 30 odd years. I don't find it noisy. A bit expensive though.
