I replaced a plastic drive gear in my “one step up from Harbor Freight” Craftsman model corded electric Craftsman chainsaw. As I was reassembling it I saw a small black tube 1 1/2 long on the garage floor below where I was working. I have no idea if it came out of the saw. It’s totally unfamiliar to me. It is not shown on any exploded diagram I can find nor is there any obvious place for it. It’s ribbed or threaded on the outside, and is very flexible. Pictures attached. Kind of afraid to reassemble without it. My only thought is it fell out of the plastic tube that runs to or from the oiler pump to limit the flow of the oil. IDK. It does fit nicely inside but I wouldn’t want to put it there without confirmation. Just asking here due to the wide base of the forums knowledge and experience. Hoping someone can advise.36C2F2FB-93B1-4E05-A111-095987E9875D.jpg51844443-8B96-4DE1-8ED2-C93A5EA4A8E3.jpg Wasn’t sure which topic to put this in. Admins feel free to move it.
