Okay, bicycle repair question. What tool do I need to remove these? (1970's vintage bike) (Thanks all! Answer: pin spanner and bottom bracket wrench... all available from park tool for the price of your firstborn LOL ) #BikeTooter
@ai6yr You could probably break the lock ring loose with a pair of channel lock pliers. Once you have that loose, the bearing cup an be turned out by hand. There is a special tool for the bearing cup, but its main purpose is to hold the cup in place while you reef down the lock ring.
@ai6yr When you reinstall the cup (with freshly greased bearings), you need to get it just right. There must be zero play (it has to be snug) but freely turning (no binding).
@yoused Thanks! I already did this with the Schwinn Varsity with great success.
@ai6yr I had a Varsity for about 15 years. I gradually replaced every part on it with something better, including the frame (Letour). It was the bicycle of theseus.
@yoused LOL... Well, right now, just the gasoline expended to haul this project bike home. It looks to be exactly the same bike as the Varsity I restored, except larger tires. (Mysteriously, one tire is 27x1 and there is a 700CC tire not attached. 🤔). Since the seller graciously provided tires/tubes for this, it looks to me like the investment here will be chain, brakes, brake/shifter cable maybe (could re-use them, but they are circa 1974....). The big question is whether I paint it or not, really.
@yoused Yes....This one, also.
