im working on a 582 for someone. its a CCC produced machine not an IH. the clutch pressure plate will not disengage from the friction disc. this is not an issue with the throw-out bearing as the throwout bearing compresses the spring like its supposed to. there doesn't seem to be a teaser srping, seems to me missing, is that the issue. when you operate the clutch with the engine off, the tension gets taken off pressure plate but the pressure plate doesnt pull away from the friction disc, it just rests against the friction disc and the driveshaft continues to spin. if it was in gear it probably would come to a stop but in neutral you can not put it into gear
