Got the black rubber gloves on and did a semi physical on the saws and found this on the clutch drum for the 395xp. The clutch pack looked good, no bluing at all there, but the drum as you can see is quite scorched. This saw is used with the 36” Alaskan mill . The 372 I use with an internal clutch drum looked great, this saw is used with the Alaskan edger in a veritical position. Both chains are sharp, I know this because I was getting zero stretch out of the two after the day was over last Sunday. Also I sharpened them before they were brought out. The only thing I can think of is that I did not and have not used wedges with the 395xp and the 36” Alaskan mill. Could the wood be pinching slightly on the blade, causing the saw to work harder? I always thought the wedges were used for better wood face appearance. I would appreciate what you guys would think.
