The crank is a little gear on a short round shaft. If you stick your screw driver, find the shaft then slide til you bump into where the gear is, it's pretty easy to move the crank up or down by feel with a skinny flat head. The adjuster gear is slightly above the hole in the rotor, maybe a half inch or quarter inch up.reviving this one from the dead, but has anyone else tried to do this and the hole through the rotor doesn't line up with the crank? I have to take the rotor off to adjust
