so i figured it would be a great idea to take my bike apart this weekend and clean it and put it back together.
i then say to myself very proudly, im a computer technician, i take stuff apart ALL THE TIME and more often than not put it back together, ive taken my camera lenses apart when needed and they still work, various electronic devices and the ilk, a bike, CANT BE THAT BAD.....
so i go, i remove the wheels, a friend showed me how to put a tube and tire on properly, so i do, front and back, then i see that horrible disgusting chain that hasnt been cleaned since the bike was built, in 78'
i learn how to break the chain, remove it from the gears, clean it all up, same goes for the front gears and derailler and back. i then look proudly at all the clean shiny metal and think, damn thats a good job.
manage to get the chain back together, with slight problems, the chain pin ended up bending out the side of the link, and after fighting with it for about 15 minutes, its mostly together ( i didnt take a picture of the link in question, but i will when i get home.
but the main concern is that the chain isnt on properly. i asked my father (who knows more about bikes than I, not by much at this point i gather) and he says i did it wrong and to do it this way (another incorrect method). so the chain is on, but doesnt crank properly, there is extra slack at the bottom and things are VERY stiff, i guess i might have overtightened things.
attached is a photo, i want to avoid taking it into my LBS because i dont have the 80 bucks for a tune up, going to go to an open workshop on thursday, id love to ride before then, but its not in my financial means.
Thanks all in advance for whatever help you can provide.
Can you shift into your lowest gear? It looks like the derailleur is not set right - it looks too high to clear the largest cog and should hang down more as xenologer mentions. Did you actually take the derailleur off the frame? The cable coming in also looks too tight - if the derailleur were tilted down a little more, the cable would be at a more relaxed angle, the pully cage would hang where it should, the chain would tighten up, and the upper pully would clear the largest cog. And those worn pulleys need to be replaced. The chain looks very dry, try some Tri-flow on each link and let it sit for 30 minutes.
One thing I learned long ago was to take pictures of everything BEFORE I started tearing it apart. It has helped me countless times on more than just bikes.
Try all of the above and check the chain's links one-by one for stiffness. If you find a stiff or tight one, usually the one you messed with, wiggle it side to side to loosen it. The links should be loose with littlee or no roughness or tighness.
