High pressure water might be a better way to clean the sheaves up, hot if possible. Or scrape it off with a knife held flat? You probably could use emery paper but you wouldn't want to rough the surfaces up at all I would imagine.

Emory cloth is fine, I did it to mine after smoking a belt and never had any issues after putting it back together. I went coarse, medium and fine. it doesn't have to be super smooth, the belt will wear it in pretty quick.

LIVE AND LEARN, as they say. The extreme heat generated by the 20 mile run back to camp actually melted the belt rubber INTO the surface of all four sheaves (primary and secondary). After days of trying to remove the burnt rubber off of both the primary and secondary sheaves with emery cloth, I got frustrated and put a wire brush on a drill to them. Big mistake !!! The heat generated with the wire brush took off the rubber, but also melted the surface and I ended up with globs of aluminium on the surface making it very rough and by any standards unusable for belt use. So a new secondary and primary sheave were ordered as well as the dust guard that goes behind both clutches as it also melted in the process. Got most of my parts, but have been waiting for over a month for my Hot Rod Sheave kit from PBS. A very expensive mistake on my part for not making sure that my primary was properly assembled the first time.
