Without more information - model of bike, reason for wanting to remove crank arms or crank bearings, what tools you have available - it's not possible to offer detailed help.

Special tools are required to remove the bearing keepers on the crank. Pullers designed for the pedal arms are needed too. You can get these tools here: Bicycle Crankset Tools Mount or Dismount Your Bike Crankset

HOW DO I REMOVE THE CRANK


If I remember right the threads on the pedals are left handed, which means you turn in opposite direction than normal. then you unscrew the nut on the crank. The race for the bearings will have a slot. Use a screwdriver to turn it the normal way. Take out that bearing. Then move crank a little way to the other side to get bearing out from the inside race. Then you should be able to pull crank through.
On the newer bikes, the crank can be dismantled on each side so all you have is a shaft to remove. You still remove the race and bearings the same way.

Need to order tools to repair 29" mongoose crank assembly


Those look like standard three piece cranks. You need a special drank removal tool. The one made by Park Tools for pulling square taper cranks should work, CCP-22, they are about $15 at your local bike shop (LBS) or online. If you have Octalink or spline drive cranks they have a tool for that too.

The cranks are usually held in place with a 14 or 15 mm bolt or nut on square taper bottom brackets and you can use a regular ratchet and socket to remove these. Once removed, you thread in the crank removal tool (mentioned above) and then turn the handle until the crank comes off (this is very tight and takes a lot of "elbow grease" to turn the tool handle).

To remove your pedals, you can use a 15mm open end/box end wrench to remove them. Keep in mind that pedals thread into the cranks in the same direction on both sides, so in other words one side is reverse threaded (this has always been the non-drive side crank).

Assembly manual


To remove the crank (the arm the pedal is attached to), you'll need a special tool. I got mine at a bike shop. (Bike shops are our friends.) I use the Park Tools CWP-7. It's pretty much a big bolt with a smaller bolt going through it. You'll remove the cap covering the spindle bolt (if it hasn't fallen out already), remove the bolt that holds the crank are onto the spindle, then thread the "big bolt" part of the tool into the threads for the cap on the crank. You'll then screw the inside bolt into the big bolt, which will push the crank arm off of the spindle.

I need to take my bicycle crank apart


I assume you have a three piece crank (axle plus two crank arms). Go look at the Park Tools website. You will need to remove the little hubcap about the size of a 50 cent piece, then remove the nut on the end of the axle, then use a crank puller to pull the crank off. The crank puller is like a wheel puller in that it has a bold in the middle the pushes against the end of the axle, but instead of having jaws the hook on the outside of the wheel, it has a large male thread that screws into the threads where the hubcap was screwed into. Good luck.

I am trying to remove the crank form a bicycle


There are different types of cranks and attachment methods. You probably have what's called a "4-sided taper" which means the attachment has 4 faces (like a bolt and socket with 4 instead of 6 sides) and when the crank is attaches, the bolt literally squeezes the crank onto the axle.

Yes, it takes a special tool.

You can buy one here: http://www.benscycle.net/index.php?main_page=product_info&products_id=796&currency=USD (This is *probably* the right tool, but without knowing the type of crank you have, it may not be!)

But it's probably cheaper to take it to a shop unless you're going to keep using the tool.

Why are you removing the crank?
