On the topic of bars. We have a 661 with a 36in bar. Bar is only a few months old, seen a hard life with the last couple jobs it was used on. Chain is new and bar chain tension has been good but it seems to throw the chain off the bar on the bottom around the sprocket. I’ll come off throttle and it keeps falling off the bar just right there. Any ideas? I have a bar file and have gone over it and seems fairly true and straight but I can’t get it to stop rolling off the bar
I used to do that, but now I leave the bar down to reduce the chance of the chain jumping. I have not had problems with the bar moving back up and slacking the chain, except occasionally on small saws that only have 1 bar nut.I may be suggesting something sort of teaching to suck eggs but...
Are you holding/supporting the tip of the bar when you do your final tighten? If not it WILL walk up when you go to cut and put just a little slack in the system.
Easy rule of thumb. "No sag, no drag."@biggun yeah right before it started doing this a chain got stretched so far it wouldn’t run right. Put a new bearing, sprocket, and (newish) chain on it. Shortly after I did this the chain started wanting to throw itself off.
@SeanKroll I do the normal tightening method. Lift bar nose, tighten chain until it makes full contact with bottom of bar, tighten front but first then back. I always hand spin, run the chain, and double check the tension before I go cutting
