Thanks for this wonderful video. I managed to destroy a roller (poorly positioned in an Alaskan chainsaw mill). This gives me the insight I need to tackle it!
Simon, thanks for that, yes I might be bale to drill the feed hole out. The steel is tough and the existing hole is the same width as the bar groove, maybe an extra parallel hole, or just better maintenance. These bars are mainly used on hardwoods and they get a really rough life compared to softwood use, cheers
Ade, yes I think you are right on the lubrication front, there's so many things that can cause a problem, increasing the flow may help, but then that's a pollution problem, cheers
@@bootsowen Owen, I cleaned then out with a bit of bicycle spoke, they work is a difficult environment especially on hardwoods. I'm thinking along the lines thornwarbler suggested, but it's tough steel that work hardens. Don't want to leave a snapped off drill in there, cheers
Thanks Andy really interesting to see your repair. Is it the height of the roller bearings that stop the two bar plates binding the tooth wheel when you tap the rivets down home?
Hi, the central disc on which the bearing run is slightly thicker than the sprocket and the bearings, so the sides of the nose clamp against that, cheers
Thanks Andy, I have been following you for a long time and have a similar view to life as you. I had to change my name to my radio callsign due to trolling. Im the guy with the small Wood in Nottinghamshire. Have a go at repair you have nothing to loose and everything to gain. Cheers.
Evening I had a go at similar , nose on bar of my 026 Stihl had locked up , the rivets are very hard metal, it suprised me as rivets are usually soft like the nail. Turns out it had nylon fishing line in there ,had made a nice nylon washer either side of the sprocket , didn't quite get back together as those rollers wish to escape and hide,and I had a nr new spare bar so used that . I have the sprocket minus one roller. I used paper to try to reassemble , may have stole the idea from one of our vids I forget . Interesting video, don't know if it's my end Andy but your videos are a bit blurry? All the best 👍
Tom, I always reference external sources of info, it's only fair. This method came from experiment, trial and error, it's the only logical way to get the nose back into the bar. As to quality, I upgraded my cameras 6 months ago, so the quality issue is probably at your feed or equipment, cheers
