What kind of sled do you have? When was the last time you put a new belt on? when was the last time you cleaned the primary and secondary clutches? also check the track tenion. I would check these first, i'm sure someone else will chim in and give you a couple more ideas.
97 ZR580. clutch's are clean, tried new belt still the same. had my crank break before and my primary was spinning around in the tub. rebuild the engine with new crank, but thinking my primary might be messed up, what should i look for. thanks
If the clutch hasn't be serviced in a while now would be the time to do it before something bad like injury or further repairs result. I'd pull it and look at everything. Yes the weights should have minimal movement left to right. It could be they need to have the bushings replaced in the weight arms. If left alone, they will tear up the spider rollers and egg shape the weights, notch the bolt the weight go on and this can cause them to stick at partial opening. Check to see also that the rollers roll easy in the spider. If the rollers are bad as you said I'd think it would be cheaper to buy another clutch. Uncalibrated. Buying one off e-bay usually means additional money spending that someone else didn't want to do. Most clutches are shot or close to it if not serviced when they hit around 2500 miles.
