Had a sprocket failuire on my new 346xp this weekend. It was the rim type with 2 peices. Upon visual inspection it looked like the cog weld seperated away from the outer clutch housing. It happened when the saw got it's first hard cut into a 19" dia red oak. The saw is under warranty luckly. Have others had this happen. I'm thinking the saw is just to damm fast!
