I need a little help. I just received my driven clutch spring from Cartpartsplus. The instructions say to remove snap ring.... I have a different type clutch it seems. There is no snap ring. The end that is supposed to have the snap ring looks to be pressed in. There is a large nut on the other side. So far this nut has been impossible to remove. That makes me think that it isn't supposed to come off. Can anyone help? Do I just remove this nut and proceed with replacing the spring?
