How to Use a Cotterless Crank Puller Tool

How to Use a Crank Puller Tool

  • Crank pullers are commonly used to remove the crank arm from many types of exercise bikes. The tool can be used on most brands of indoor cycles and stationary upright or recumbent bikes. This tool cannot be used on bikes equipped with a 1-piece crank arm.
  • Using the crank puller is simple and easy; Start by removing the crank arm bolt.
  • First you will need to remove the plastic crank bolt cover from the crank arm to access the bolt. This can be done using a flat head screwdriver or a penny from your pocket.
  • Remove the crank arm bolt. This can require a hex wrench or a socket wrench.
  • Next, thread the crank puller tool into the crank arm in place of the crank bolt cover. Thread the tool into the crank arm several threads. It may be necessary to use a wrench to tighten further.
  • Now that you have this part of the tool threaded into the crank arm, turn the handle on the tool. As you continue to turn the handle of the tool, this pulls the crank arm off the bottom bracket shaft.

The right foot pedal has fallen off on my model recumbent cycle. The threads of the crank arm seem to be shredded. What do I do?

This can happen if you do not make the pedals tight enough when you first install then. Contact the manufacturer or seller. They should carry the crank arm. Note that it takes a special tool to replace a crank arm. Most bike shops have crank arm pullers for sale. You can contact the manufacturer to see which crank arm puller is required. When you install the new pedal, make it very tight.

Can't remove right pedal shield

The shield will not come off unless you remove the entire crank, not just the pedal. to do this, you need to buy a CRANK ARM PULLER TOOL available for around $15.oo at any bicycle shop. Make sure to get one for a square tapered bottom bracket. Just used one, the crank came right off and the shield simply lifted away. here is a link to a YouTube Video showing the tool and explaining the process: https://www.youtube.com/watch?v=N63ofGcRCYQ

problem removing crank arm off of a mojave gulch bycicle from huffy

There's a special tool called a "crank puller" that has to be threaded in to the crank arms that are on your bike in order to remove them. An inexpensive version of the tool will cost around $10- which is about the same price as a shop would charge you for the work.
If you *do* want to remove them yourself, please be sure to thread the crank puller in perfectly straight and very, very carefully (backing in all the way out and starting over if you encounter resistance). Once you have threaded it almost all of the way in to the crank arm by hand, grab an adjustable wrench and tighten it down before you spin the handle to push the arm off of the bike. (If you fudge it and damage the threads inside the crank arm, you will have to pay a shop to bash them off instead- another special tool is used for that.)

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?
