I am not waiting on rings, i have some coming should ship out monday and be here by weeks end. that ring just pulled apart like white bread, the second ring allowed me to pull on it and it got installed.
I just noticed something they have very little showing on the website for the 070. They need to get the parts posted so we don't have to ask and hope. I got worried when i could not find the 10x1 left hand threaded nut that you put on the clutch side crank stem. I just could not find it. So I drove to the areas largest old timey hardware store its like two stories and 4 city blocks in hopes of finding one and they had one but it was coarse threads, not what is needed. I took the case in with me and the stihl tech questioned me on how my saw was so clean. Thats code for fake, lol . i let it lie and he came back at me and i told him it was aftermarket and he so Oh! He wanted to touch it, i know he did, he never had touched one. They called ever dealer in a 70 mile radius for me (told you old timey, actual customer service) and of course no one had it. so i am telling you this charming story to let you know that you need to be on top of it.
I got back home and looked one more time and it was standing up on the blind side of the small box i put everything in. it comes packaged by itself and its silver not black like the ones we often use. so i decided to get some rings right now and move on to ensure i can get the kit completed.
i wish i would have made a packing list for each saw and then have done build the videos. we buy the kits and the day we get them we check off whats there and whatever is not, we get to having it sent right away rather than later finding something missing and having them, then they tell you they don't understand send them a drawing of where it goes or send them a picture and then they can't see it. lol. if you run into something like that you can take a screenshot of an ipl and sent it off.
