I'm fixing up an old Sears 3 speed men's model for a Winter project. It's coming along nicely and cleaning up well considering how bad it was when I picked it up (amazing how differently it looked in person, as opposed to the eB*y pics!).
I'm guessing it's a Puch, as the decals said made in Austria (though the frame is stamped made in Germany).
The 3 speed hub seemed to work in all three gears while the bike was inverted. Couldn't ride it as it had two flat tires. The hub is stamped "3 3 3" then underneath that: "3 Speed Hub".
I'm not going to mess with the internal workings unless it's proven necessary later. What lube goes into the hub and how much of it? It seems to be empty, but not dry. I have to guess a light oil just by the size of the fill opening. Think Prolink Progold chain lube would work? How much of it?....fill it up just doesn't sound right. Thanks!
