I was almost done with this bike when I thought; “That crankset seems a bit rough. I better repack those bearings.” It was the ancient kind that uses an axle, bearings, and cups instead of a simple axle/bearing cartridge that just screws into the frame.
The axle cones were blown. Where there should have been a shiny bearing-track were pitted regions that foretold broken bearings and failure.
This was specially annoying because, in an ill-advised attempt to clean up the garage, I threw out a bunch of old bike parts last year. One of those parts was a Tagaki crankset assembly identical to the one I now held in my hand. I had thought; “When am I ever going to need one of these?”
Well, now, for instance. “The lesson is, never throw anything out,” my son said. (Unfortunately, this is the de facto policy of our household, which is the reason there’s so very little space in such a large house)
MrsDoF and I had lunch at Wendy’s, and then we checked a trash pile where I’d seen a bike old enough to have that kind of crank – it was gone. We pulled into the driveway and I said “Goose chase”. Or rather, Goose-egg.
Except… hmm… while I might throw out a cheap crankset, it wouldn’t be like me to throw out the axle. After all, an axle takes up hardly any space at all. And axle cones fail even when the cups themselves are OK; it’s just where the force of operation is most concentrated. In fact, I probably would have tossed that axle into my parts bucket. And being heavy, it would find its way to the bottom!
Which it did. Now all I need to do is go buy two bearing races (cheap) and the bike is ready. :coolsmirk:
