What Can You Use Instead of a Crank Puller?

A crank puller is a tool that helps you remove the crank from your bicycle. It's usually used when adjusting or cleaning the bike, but can also be used to replace an old one. They are usually inexpensive and easy to use. But what do you do if you don't have one?

A screwdriver: If all else fails, a screwdriver can be substituted for a crank puller as long as it has a wide enough head and is relatively sharp on the end of the blade.

The key here is to try not to damage any threads once it's in place, so apply gentle pressure while turning the screwdriver counter-clockwise until it pops out of place with some force (about 1/4 turn). This should

If you are trying to remove a crank from your bike, but don't have a crank puller, there is an easy way to do it. All you need is two pieces of wood and some rubber bands or string.

The first thing you need to do is put the wood on either side of the bottom bracket spindle. Make sure that they are standing in opposite directions so that one end can reach around the axle and the other end can go over top of it as well.

Put one rubber band or piece of string around each end and then cross them over each other in order to form an X shape; this will be used as a handle for pulling out the crankshaft later on! Now all you have to do is tighten.

The bicycle crank should be solid, not wobbly. If you have a wobbling bike crank, it could mean that your bearings are worn and need to be replaced. This blog post will explain how to diagnose and replace a bike's bottom bracket bearings.

It is important for the cyclist to know what their position on the bike is before replacing any parts of the bicycle. A good place to start is by examining the chainrings at either end of the crankset (the set of gears where you pedal).

The teeth should look like they're in line with each other - if one or both are out of line then this may indicate that a bearing has come loose and needs tightening, or worse still that there's been some damage done

This is a blog post about why your crank might be wobbling. Cranks can wobble for many reasons, but we'll talk about the most common three here.  First, your bottom bracket might not be tight enough.

This can cause the crank to loosen and wiggle around in the frame of your bike while you ride it. If this is happening, you need to tighten up that bottom bracket! Second, if there are any play or gaps between the pedal axle and where it attaches into the crank arm, then this could also be causing some issues.

Finally, if you have loose pedals on your bike (as opposed to clipless), then these could also be causing some issues with rocking back and forth as you ride. You should.
