This is a very old 286 that hasn't been used in a long time. I want to use it again. The drive line was froze up to where it wouldn't extend so I took it off by removing the bolts and springs & nuts of the slip clutch. There was one clutch lining that crumbled up when everything came apart. I went online to find new parts, and I see different makers on the driveline, but they all have 2 linings. This one doesn't have the inner plate that would use a 2nd clutch lining. The thing couldn't come out on it's own. I don't understand why somebody would have removed it, if that's what happened. This slip clutch looks like it was built with one lining. Has anyone else seen this?
