How do i remove my sprocket off a dk bike with 3 piece cranks?

Answer 1

you don't need any special tools. I've been riding BMX for ten years and never owned a crank puller. Depending on the cranks you have will depend on the tools you will actually need. Generally you need a set of allen wrenches. The hexagon shaped tools.

Look at your cranks. I'll assume the sprocket is on the right hand side. Look at the right hand side. See the crank arm, one end has the pedal tightened on. The other end should have a bolt facing you and possibly a couple of bolts clamping the crank arm on. If the crank arm is clamped down onto the spindle(piece that holds the two crank arms on), undo the one or two bolts that will be there. Now undo the larger single bolt that is screwed into the spindle. Now go to the left side of the bike. There should be a smaller bolt holding the sprocket on. Undo that one. Your crank arm should come off, it may need some gentle tapping. If it's stuck, s***w the bolt back into the spindle about 7-10 full turns, but not until it's tight. Tap with a hammer on the bolt lightly to help push the spindle through the bike, while pushing out of the crank arm. If it's really that stuck. Run it over to the local bike shop and they should be able to help you out for a buck or two or free if they're a decent shop. Sprocket should be free now with the chain still intact.

Reverse steps to install. Remember not to force anything or hit anything too hard. You will bend and break things and it's not worth it. Just ask someone who has gone through many, many parts over the past ten years..

if its a sealed bearing crank then yeah a crank puller, but if its not you should just un bolt the end caps and loosen the arms and pull em right off.

Answer 3

You need a special tool called a "crank puller".

No, I'm not kidding.   Any good bike store will have one.

I love bike tool names.
