removing derailleur on bicycle without buying a chain tool?
First off I am extremely cheap. I got an old bike at a garage sale for $5. one gear in the derailleur has half of the gear missing (cracked in half). Rather than buying a new derailleur, going to just make it a single speed. A chain tool would be the simplest way to go, but I am cheap and would rather not spend $15-20 on that. I tried ripping the fucked up derailleur apart, but it will not budge, no idea how the dude managed to break a gear in it, the thing is beefy. Any advise on how to cut/break a piece of metal so i can get the thing off? (tried a hammer, prying at it with a screwdriver, prying at it with a crescent wrench). I am thinking electrolysis (not sure how to set that up exactly, but I think that would weaken the metal). a torch would probably damage the nearby chain (1000C is really hot).
What chemicals are very corrosive to metal? Thanks!
There are two pulleys on the derailleur that are secured by two set screws. the two cog like things… get an allen wrench and remove the set screws, remove the pulleys and then slip the chain away from the derailleur.
Set the high and low limit screws on the derailleur so the chain stays on one of the functional gears.
Is this a real question?!
On top of removing the derailleur you’ll also need to shorten the chain so you are going to HAVE to buy a chain tool or take it to a shop and have them do it… maybe $5 or $10 to do the whole works.
