Remove Cranks Without A Crank Puller
What Can I Use If I Don’T Have a Crank Puller?
If your bike has a cartridge bottom bracket, the most common type, you can usually remove the crank without a puller. The first step is to unscrew the bolts or caps holding the crank arms in place. With the bolts removed, the crank arm should come off easily by pulling it straight away from the spindle.
If it’s stubborn, tap it lightly with a rubber mallet. Once the first arm is free, repeat with the other side.
If your bike has a cup-and-cone style bottom bracket, you’ll need a crank puller to remove the crankset.
This type of bottom bracket uses bearings that are held in place by cups that thread into the frame. There are two ways to remove cup-and-cone bottom brackets: with an adjustable wrench or with a specialized tool called a Park Tool BBT-22 Bottom Bracket Tool Kit.
With an adjustable wrench: Unscrew and remove both locknuts from the outside of the bottom bracket cups using an adjustable wrench.
Turn one ofthe cups counterclockwise to loosen it until it’s loose enough to be removed by hand (it helps if you have another person hold on tothe other cup so it doesn’t turn as well). Remove this cup and then repeat withthe other side. With Park Tool BBT-22 Bottom Bracket Tool Kit: Unscrew andremove both locknuts from outside of bottom bracket cups using Park ToolBBT-22 Bottom Bracket Lockring Hook Wrench (included in kit).
Insert ParkTool BBP-1 Bottom Bracket Cup Remover (included in kit) into notches at endof one cup and rotate counterclockwise to loosen until cup can be removedby hand (it helps if you have another person hold on to frame while doingthis). Remove this cup and then repeat with other side.
How Do You Take off a Bike Crank?
Assuming you want to know how to remove a bike crank in order to replace it:
Tools needed: 8mm Allen wrench or pedal wrench, 15mm open-end wrench
1. Remove the bolts that secure the crank arm to the spindle.
There are typically two bolts, one on each side of the arm.
2. With the bolts removed, the crank arm should now slide off of the spindle. If it is stuck, try wiggling and pulling it gently until it comes loose.
3. To reattach the crank arm, simply reverse these steps! Make sure to tighten the bolts securely so that the arm doesn’t come loose while riding.
How Do You Remove a Crank Bolt from a Bike?
Assuming you want to know how to remove a crank bolt in order to replace a bike part:
To remove a crank bolt, you will need:
-A socket wrench that fits the bolt
-A piece of pipe or another extension for the wrench (optional)
-Possibly an allen key
1. First, if your bike has pedals, you will need to remove them.
There are usually two types of pedals – those with cotter pins and those without. For pedals without cotter pins, there will be a cap on the back of the pedal that can be unscrewed with an allen key; underneath this cap is the nut that needs to be loosened. For pedals with cotter pins, the pin needs to be removed before the pedal can be unscrewed ( use pliers if needed).
Once the pedal is loose, it can be pulled off of the crank arm.
2. Next, locate the crank bolt – it is typically on the side of the crank arm opposite from where the chainring is located.
3. Use your socket wrench to loosen and then remove thebolt – if it is particularly tight, you may need to use an extension for more leverage.
Be careful not to strip The threads as you loosen/remove The bolt!
How Do You Remove a 3 Piece Crank?
Assuming you want to know how to remove a three-piece crank from a bicycle:
The first step is to remove the chain. To do this, you will need a chain tool.
Place the end of the chain tool onto one of the pins on the innermost link of the chain and push until the pin pops out. Once that pin is removed, the rest of the links should come apart easily by hand. If they don’t, use the chain tool to remove more pins until all links are disconnected.
Next, use a crank puller to remove each crank arm from its respective spindle on the bottom bracket. The crank arms are usually secured with cotterless bolts (allen key bolts). Unscrew these bolts until they are loose enough to be removed by hand.
If they’re too tight or stripped, you may need to use an impact wrench or drill/driver with an appropriate socket attachment.
With both crank arms removed, you should now have access to the spindle in the center of the bottom bracket shell. Use a Bottom Bracket Tool to loosen and remove this spindle from the frame.
Keep in mind that some bottom brackets are reverse threaded (righty-tighty, lefty-loosey), while others are standard threaded (lefty-tighty, righty-loosey). Make sure you know which type yours is before proceeding!
And that’s it!
You’ve now successfully removed your bicycle’s three-piece crankset.

How to Remove Bike Crank Arm Without Puller
Removing a bike crank arm without a puller is possible, but it is much more difficult. The first thing you need to do is remove the pedal from the crank arm. To do this, you will need to use a wrench to loosen the nut that holds the pedal in place.
Once the pedal is loose, you can remove it by hand.
Next, you need to remove the bolts that hold the crank arm in place. There are usually two bolts – one on each side of the arm.
Use a wrench to loosen these bolts and then remove them by hand.
With the bolts removed, you should now be able to pull the crank arm off of the bike frame. However, if there is resistance, you may need to use a pry bar or other tool to help dislodge it.
Be careful not to damage the bike frame when doing this.
Once the crank arm is removed, you can proceed with your repairs or replacement as needed.
Shimano Crank Removal Without Tool
If you’re like most cyclists, you know that Shimano is one of the leading brands when it comes to cycling components. But what you may not know is that their cranks can be removed without the use of a special tool.
That’s right, all you need is a 4 or 5mm Allen wrench to remove your Shimano crank arms.
The process is actually quite simple:
1. First, remove the chain from the chainring. This will give you more room to work and make it less likely that you’ll damage your chain during removal.
2. Next, locate the two bolts at the back of the crank arm near where it meets the bottom bracket spindle. These are usually hidden behind a small cap (which can be pried off with a flat-head screwdriver).
3. Using your Allen wrench, loosen and remove these bolts.
At this point, the left crank arm should come free from the spindle. Repeat this process for the right side and your cranks will be off!
How to Remove Bicycle Crank Bearings
If you’re like most cyclists, you probably don’t give much thought to the bearings that allow your pedals to spin smoothly. But if those bearings start to go bad, it can make pedaling feel very difficult and uncomfortable. Fortunately, it’s not too hard to remove and replace them yourself.
Here’s a step-by-step guide on how to do it:
1. Start by removing the crank arm from the bike frame. You’ll need a crank arm puller for this (most bike shops sell them).
2. Once the crank arm is removed, you’ll be able to see the bearing cups that hold the bearings in place. Use a hammer and punch to tap out the old bearings from their cups.
3. Clean out any dirt or debris from the bearing cups with a rag or brush.
4. To install new bearings, first grease them generously with bicycle bearing grease (this will help them last longer). Then press them into place using an old axle or similar object that fits snugly into the cup. Make sure they’re seated evenly before moving on.
5. Replace the crank arm and tighten everything back up securely before taking your bike out for a spin!
Crank Puller Sizes
There are many different sizes of crank pullers, and the size you need will depend on the size of your crankset. The most common sizes are 15mm, 16mm, 18mm, and 20mm. If you have a standard crankset with 24mm spindles, then you will need a 15 or 16mm crank puller.
If you have an oversized crankset with 30mm spindles, then you will need an 18 or 20mm crank puller.
To determine the size of your crankset, measure the diameter of the spindle in millimeters. This measurement is usually stamped on the backside of one of the arms near where it attaches to the bottom bracket shell.
Once you know the size of your crankset, select a corresponding crank puller that is slightly larger. For example, if you have a 24mm crankset, choose a 16mm crank puller.
When using a crank puller, first remove any pedals that might be attached to the crankset.
Next, insert the jaws of the tool onto opposite sides of one of the arms and tighten until snug againstthe arm’s flats (do not overtighten as this can damage delicate threads).
Shimano Crank Removal Tool
If you are a cyclist, then you know that having the right tools can make all the difference. And when it comes to removing your cranks, the Shimano Crank Removal Tool is the way to go. This tool is designed specifically for removing Shimano cranks, and it makes the job quick and easy.
Simply insert the tool into the crank bolt and turn it counter-clockwise until the crank comes loose. Then just remove the tool and your cranks will be off in no time.
Cotterless Crank Tool
Most cyclists are familiar with the standard crank tool, which is used to remove and install cottered cranks. But what about a cotterless crank tool? This type of tool is used to remove and install cotterless cranks, which are becoming increasingly popular among cyclists.
There are several advantages to using a cotterless crank tool over a standard crank tool. First, it is much easier to use – simply insert the tip of the tool into the hole in the crank arm and turn. Second, it is much more versatile – it can be used on both square taper and splined bottom brackets.
And third, it is much more durable – made from hardened steel, it will last for years with proper care.
If you’re looking for a new crank removal/installation tool, consider investing in a cotterless crank tool. It will make your life easier and help you keep your bike in top condition.
Conclusion
If you need to remove your bike crank without a puller, there are a few steps you can follow. First, if your bike has pedals, you’ll need to remove them. Next, use a wrench to loosen the bolts that hold the crank in place.
Once the bolts are loose, you should be able to simply pull the crank off of the bike. If it’s stuck, you may need to tap it with a hammer or other object to get it started. Finally, reattach the pedals and tighten the bolts back up.
