I need to adjust the belt ride height on my 03 600 HO Sport, in my secondary clutch. I'm not familiar with this clutch, I'm used to having a dial for adjustment, but all I see are three bolts. Is this clutch adjustable? How is it done? I'm guessing that something needs to be done with the three bolts. My other question is that it looks like it will be a tight fit, if not impossible, to get a socket into the holes that the bolts recessed into. You can tell that I haven't tried this yet, but will a regular socket fit in there?
