Ok, so most of us know that the legendary Stihl 056's are taking dirt naps due to lack of good ignitons and non-standard sized bearings and seals on the clutch side. This thread is for me a Dave B. to track any progress on finding standars bearing and seal solutions for these saws.
I have pleaded my case to both Greg at Bailey's and several Chinese AM manufactures to make a package solution to bring these saws back to life and both feel that there isn't enough market or "meat on the bone" for them to dig in on it... They might be right and nobody cares about these dinosaurs but some of us on AS, but I believe that there has to be a couple thousand of these saws that people would mind swaping new AM parts onto and running again! Or am I crazy??? I have a bunch of 056 parts and would like to build a couple of them over the winter... Start to finish and post the info here for future members...
After talking with Dave (VERY Wise & Capable machinist!) about the problem I gave him 2x 056 crank cases that had bad bearings (one of each clutch side type bearing, since there are 2 styles). He needed to know the dimentions of the bad bearings and seals in order to research possible standard size solutions. I believe in our initial conversation the suggestion was such: if the crank's width is a standard size we match a bearing to the crank diameter. Then we could oversize/machine the case to accept a slightly larger standard size (overall diameter) bearing. hopefully this will work on one of the two types of crank case so we can use standard size parts that are readily available.
Dave if you are reading this... I believe it might be easier to start with the two piece bearing/seal design. Because if we can get a standard bearing fit to the inside of the case the outside seal can still be found sometimes on ebay and the internet. However, I don't know how hard it will be find a standard size "sealed bearing" replacement for the 1 piece design... It might be easier to machine the outside of the case and drop a sealed bearing into place... IDK... up to you!!! Can't wait to hear what you have to say!
After finding a fix for the bearing I would like to move this thread into a "How To" on fixing the ignition system with parts available. The idea is to have all the information pulled together in one thread for people to read/research how to fix these wonderfull old saws.
Igniton solutions I've seen or heard of...
1.) replace with cut off saw ignion (350TS or 360TS: SEM unit)
2.) replace with points style ignion (need eccentric: 041? any others)
3.) convert to electronic remote trigger unit (nova module)
4.) Bosch ignitons commonly have a bare wire grounded under the flywheel so check that first...
I read a thread on #3 but it seems like the OP never came back with part numbers and directions for us, and/or gave a final diagnosis on whether the solution fixed the ignition problem. So while I believe number 3 is possible, I think myself and others need more conclusive proof... If anyone has made this work, now would be the time to make thorough "how to" on this solution.
In conclusion this thread is basicaly seeking out fixes for the non-standard, NLA, and hard to find parts... Hopefully Dave will be along to share some news sometime in the not so distant future! Others feel welcome to add your expertise on the subject... Maybe shaun will be along soon b/c I know we've talked about this a bit too...
