How To Remove Bottom Bracket Without Tool? – [Step By Step]

Are you the one who doesn’t have a budget to purchase tools but wants to remove the Bottom bracket without a Tool, like me?

If yes, you are at the right time and right place;

The question is, how can the bottom bracket be removed if there are no tools available?

Taking the bottom bracket out of your bike’s frame is possible without a bottom bracket tool. You need a wrench to loosen the nuts holding the bottom bracket onto the crank arms.

After that, remove the bottom bracket from the frame using your hands.

Bottom bracket removal might be challenging, depending on the type of bracket and the resources at hand. While a bottom bracket tool is recommended for this maintenance, a few simple home tools will suffice in a pinch.

It won’t be simple, but if you put in some effort and have patience, you’ll be able to do the work.

How To Remove Bottom Bracket Without Tool?

Modern bicycles typically use one of two bottom bracket designs. We have a press fit and a threaded one on this particular bike.

The bottom bracket on your bike has threads, and we’ll show you how to remove and replace them here. To take off your bottom bracket without a tool, follow these steps:

Remove the Cranks on the Left Side:

No matter your bike’s bottom bracket, you’ll need to take the cranks off to get to the bearings. Unscrew the 8mm Allen key bolt holding the arms to the spindle, and then take the arms away from the spindle.

The bolt must be inserted into the left crank arm and unscrewed by turning it anticlockwise. Now that the axle is exposed, you can safely remove the additional spacers by counting how many you take off and storing them safely.

When reassembling the crank arms, you will require these spacers. Before you remove them from their current location, simplify the task of reassembling them by documenting the configuration with shots.

Remove the Cranks on the Right Side:

Once the left crank arm has been removed, the right crank arm may easily fall out of place on some bikes.

The right-hand crank on some bikes can be resistant, so you might need to use a rubber mallet to tap the arm loose.

However, at this stage, a metal hammer should not be used in case it dents the metal.

After taking off both crank arms, the last step is removing the dust caps, which is all left to do now. Taking them off by hand should be easy, but a light spray of lubricant might help if you need help.

When you’ve finished, you’ll be left with a bottom bracket that is completely exposed and ready to be removed.

Remove the Bottom Bracket:

Before we begin, we’d like to emphasize that, depending on the type of bottom bracket, knowing how to remove it without a tool can be quite tough.

Remove Bottom Bracket

These bottom brackets are the simplest to remove without any specialized tools. When you’re ready, here’s how to take off the bottom bracket:

  • Make sure your bike’s frame is well-protected – Wrap some fabric around your bike’s main tube. The fabric will prevent scratches to your bicycle in case of an accidental misstep.
  • To remove a threaded bottom bracket, you must first break the seal. As a rule, the bracket is flush with the bike frame, leaving little room for a rider’s hands.

The bracket can be secured in place with the help of a pair of locking needle-nose pliers. Turn the wrench counterclockwise as far as it will go to release the bracket.

  • Remove all of the threading from the bracket. A few recesses should be on the bracket designed to hold a bracket tool.

They’ll help you loosen the bracket’s threads without stripping them out as you work. To remove the bracket, loosen it by pressing the tip of a screwdriver into the indentations and rotating it.

  • You can remove the bracket by unthreading it completely and then pulling it out of the frame with your hands.

If it will not come out, the bracket is still threaded in place, and you will need to continue working through the process.

Utilize this opportunity to clean the bracket since your hands will likely become greasy during this procedure.

One-Piece Crank Removal: Bottom Bracket:

You can attach a one-piece crank bracket, which is manufactured from a single metal component to a minimalist bike frame with ease. Now follow these steps to remove one piece crank bracket:

  • Take off the left pedal. This optional first step will offer you more space to deal with and make the job easier.

Though pedal wrenches are available for purchase, you can also remove a pedal by clamping two hex bits from a screwdriver set to an adjustable wrench and giving it a vigorous spin.

  • Taking off the lock nut reveals the left-threaded lock nut securing the left-hand crank. Turning the lock nut clockwise with a 30 mm spanner will loosen it enough to be unthreaded by hand.

Take out the key and washer underneath and put them somewhere safe. To put the bracket back together, you’ll need those parts.

  • Loosen the cone keeping the bracket in place – Once the lock nut has been removed, you can access the cone. The openings in the cone can be pried open with a screwdriver with a flathead tip.

These notches are for a bracket tool, but a screwdriver head will fit them just fine. The bracket can be unfastened by applying angled pressure and turning it clockwise.

  • After you’ve loosened the cone, you’ll see a tiny metal cage holding the bracket in place; remove this cage. To take it out of the bracket’s interior, use your screwdriver or pliers.
  • Rotate the one-piece crank anticlockwise until it retreats from the bracket, and then you can pull it out.

Nothing is keeping it in place, so after some initial discomfort, you should be able to pull it out yourself.

Avoid damaging the crank’s gears by placing it on a flat surface with the gears facing upward.

Techniques for Removing a Press-Fit Bottom Bracket

Press-fit bottom brackets are installed on your bike and require some effort to remove. Because of internal pressure, these are the most challenging to remove by hand.

It will take a good whack with a hammer to separate the bracket from the cup, as it is firmly stuck against the cup’s inner wall.

Do not do this without the appropriate equipment; it will not go well. Bottom bracket tools are helpful. However, it’s easy to ruin the cup when installing a new bearing, rendering the tool useless.

Press-fit brackets come in a wide range of sizes, adding another layer of complexity. Regarding removing press-fit brackets, some bracket tools won’t do the job for thinner ones.

You need to get the appropriate tools to avoid the hassle of changing a broken bicycle, which is impossible if you are limited to press-fit brackets.

There’s no point in causing damage to your bicycle to learn how to remove the bottom bracket without a tool.

Why Is It Necessary to Remove the Bottom Bracket?

There are several reasons to remove your bike’s bottom bracket. It’s usually because the bearings need to be changed. The crank may feel loose or unsteady if the bottom bracket bearings have worn out.

Removing the bracket to replace the spindle is another reason. The bottom bracket spindle connects the crank arms. If it gets broken, you’ll need to replace it. Finally, remove a bottom bracket to wipe mud or filth that’s blocking your wheels.
