Hi everyone. Posted a question on my 039 seeming to bog and choke with chips in the cut yesterday, and asked about if a larger felling dawg might help. Well, after cleaning the saw this morning, I took the bar, cleaning the oiling hole and bar groove, and noticed that the spocked didn't spin when I hit it with air. Figured there was a little junk in the sprocket that might need to be blown out. Tried to turn the sprocket by hand had realized there was a problem. The sprocket will turn fairly freely for about 1/2 turn, and the second half of the turn is VERY tight. Almost too tight to turn by hand and needed to push with tool to make it turn the whole way. Also notice some bluing on the nose of the bar - two small sots on the rail, above and below the nose. So..........I'm guessing now that the reason my saw was bogging might have been related to the nose failing? Would that make sense? The bar is basically brand new - bought in August and only cut about 1/2 cord (it's a rollomatic e). I can't remember ever pitching this bar hard, etc., so not sure what happened. Is the bar repairable, or am I looking at having to buy a new bar? Thanks for any help! Cheers!
