the only part i disagree with is having the bike 'in gear' and even though the force applied is through human strength i just don't recommend it.garth285 said:if an impacter doesnt work then use a large 2 foot or so breaker bar and I have done this a few times but with the bike on the stand or the kickstand put it in gear roll the bike forwards until the gear stops it (this is so that theres no slack in the chain) and hold the rear brake at the same time and just crank on it, ya need some muscle to do this but it will sometimes work better than sitting there with an impactor or torching the nut to break it loose.
Whoa nelly. I bet that was a bad day. I can't help but laugh at that though.12RPilot said:My buddy borrowed a 1" impact wrench from his freind the truck mechanic. Then he cranked his air up to 170#. Put the socket on the sprocket, pulled the trigger and launched the bike through the drywall and broke several boards on the garage siding. Moral of the story: stick a board or something across the swingarm and through the back wheel.
Now, I don't know shit, but I worked on helicopters for 10 years and this sounds like the best way. This way, the counter torque is absorbed by the chain on the old sprocket and none of your internals get hit.leemille said:i wrap an old piece of chain around the socket, clamp it with a pair of vice grips and stick an 18" breaker bar thru the vice grips. that's one side. the nut is then attacked with a 1/2"x18" breaker bar with a socket. the nut come right off. be sure to clear the safety washer before starting to remove the nut.
