Trying to replace the starter gear on the bike. Took the case cover off (forgive me if I use the wrong terms). I believe it's the primary chain (that wraps around the alternator? and clutch). We need to get the sprockets that are apart of the alternator off but it has a large nut holding it on and we can't figure out a way to keep the stuff from spinning on us. Any idea's on how to hold it so we can break that nut free? I can get some pics if need be.
Edit: can I assume this is a lefty loosy situation or is it reversed?

We pulled that cover off and behind it is where the nut we need to figure out how to get off is sitting.
