That's an outstanding old Mac!
When removing 6-10 clutch I may have done just that or it was already cracked and just showed itself upon loosening. The metal was so brittle. Ran it today and cut for about ten minutes and all was well. I am leaning towards already cracked as the performance is everything I could want with the 55 clutch installed. Mark I placed that copper patch on the wrap handle and it will work out fine. I have zink plated machine screws in place but will change out to something softer in case I throw a chain.If the tapers were clean, dry, and fit well and the clutch nut properly torqued (book says 160-170 In/#) it should be O.K. Since you put the clutch from the PM55 (no keyway) on the 6-10 (keyed crankshaft) you may be able to up the torque a bit. Never go overboard when tightening the clutch on a RH start saw with the keyway in the spider, they will break very easily.
