Greetings, my first question here. I searched on Eco and read about 10 pages of posts, however didn't see this question. disassembling a series 90 Eco air meter. Ron Scobie has helped me out a lot, but now...well, now I have a problem. In removing shaft that has the number wheels on it I found that the second wheel (2 wheel meter) will not come off. It rotates on the shaft, and it appears it is on a bronze or brass bushing. The bushing is what is stuck. I can't find any mention of the bushing nor anything showing a split pin or set screw holding it on in the paperwork I have. All spacers and the first wheel slide easily. Anyone else have this experience or knowledge on what to do? Even thought of cutting the shaft, but Ron is out of them at the moment, and that is a last resort. I truly appreciate any help and/or insight on what I am doing wrong.
