Bike Tips - Installing the Sprocket

Installing a new sprocket is not such a big task as people make of it. These simple instructions should make it easier. 

1) First step is to take the crank arm off of whichever side the sprocket is on, to do this just get the right size allen key to take out the main bolt that runs through the center of the arm, next you will have to untighten the other allen key screw that clamps the arm on the spindle. 

2) Now that u have the arm and sprocket off as a whole, you want to take the right size allen key and unscrew the crank bolt completely from the backside of the sprocket. 

3) Once this is done your sprocket will be separate from each arm, you also may need to pound out the spacer from the whole in the middle of the sprocket. 

4) Now your going to get your new sprocket, put the washer inside the middle and screw the crank bolt back on so the sprocket and arm are re-connected. Now you have to slide the crank arm back on the spindle and put the chain on ( if your going down in sprocket size you will need a chain breaker to take a link out) once you have the chain sized right, put the arm on the spindle and set the chain up, tighten the main bolt and give a few cranks, if u hear cracking you need to take out a washer on the spindle so the sprocket and rear cog line up perfectly. 

5) Once everything is all sized and ready to tighten, lube up the spindle with some good grease, tighten all bolts and go ride.
