Schwinn Sprint Teardown

Today I have an old Schwinn Sprint from the 1980s that could use an overhaul:

The chain is pretty rusty and the cables don't move so well. The dusty frame probably means it's been sitting for a number of years. Well, it's time to have some fun with it. This bike is pretty similar to the Fuji road bike I redid a while back. I'll start with removing the pedals and cranks this time:

14mm socket on the crank nut:

Puller tool for square tapered cranks:

Now the cranks are off, I can remove the lockring on the adjustable cup:

Unthread the cup and the spindle comes out:

 

The fixed cup comes out with a big wrench and some persuasion (remember this guy is reverse threaded):

 

To repack the headset bearings first I need to remove the shifters (a Phillips screw on these Suntour friction shifters):

Next the brakes (a 10mm nut behind the fork, a ratchet makes this easier):

 

Loosening the allen bolt on the top of the handlebar stem should let everything slide out:

Now I can remove the headset's top nut:

Then the top bearing race will unscrew by hand:

Bye bye fork:

I'll remove the chain and soak it in motor oil:

This pile of bits used to be a bike:
