Wow, you stop after 25 miles to break 'em down? I guess if it's at a food stop you can schmooze and eat while working on them.
We had an entire day of hub antics at SchwinnSchool min 1969 and one of the instructors was an ex-magician and made it look very easy. Holding the 'stack' of parts between his four fingers, he plopped them on the axle before we could see how and what was done.
The shopmate with whom i attended, 30 years my senior, lost many pawl springs on the carpet. It was 4PM and he was very jittery being 8 hours after his morning eye-opening last swigs of Old Kentucky and just an hour away from his evening cocktails. Being at the school, he could not dip away to his old buick for the customary drinking of his lunch.
It was about that time that SA went from machined-and-hardened gears to compressed powdered metal. the former were said to be stronger.
We did the AW and TCW (coaster brake) models but also were taught to fix the Shimanu type FA (Schwinn joked that it stood for 'Falling Apart' )Shimano three speed hubs.
Not long after that class did Schwinn embrace so much from Shimano. Huret yielded to 'Schwinn Approved Shimano-made Derailleurs and the Shimano three speed hubs as well for infernally-geared machinery.
Fun stuff.
