Mountain biking is an adventurous and thrilling activity that demands proper maintenance and care of the equipment. One crucial aspect of maintaining a mountain bike is removing the crankset periodically to clean and lubricate it. The crankset is the component that connects the pedals to the bike’s drivetrain, and it is pivotal in providing power to the bike’s motion.
Removing the crankset typically requires a specialized tool known as a crank puller. However, if you are stuck in a situation without the puller, you might be wondering how to remove the mountain bike crank without puller. In this article, we provide a step-by-step guide on how to dismantle the crankset without using a puller. Read on to know more!
Tools Required for Removing a Mountain Bike Crank Without Puller
Removing a mountain bike crank without a puller can be challenging but with the right tools and technique, it can be done easily. The first thing you need is a 5mm Allen key that fits your crank bolts. This will be used to loosen the bolts that hold the crank arms in place. You will also need a rubber mallet to remove the crank arms from the bottom bracket spindle.
Next, you will need a pair of pliers or a crescent wrench to remove the dust cap that covers the bottom bracket spindle. This will give you access to the bolt that holds the spindle in place. You may also need a flat-head screwdriver to pry off the dust cap if it is stuck. Finally, you will need a socket set or a wrench to remove the bolt and washer that secure the spindle to the bottom bracket. With these tools at hand, you are ready to remove the mountain bike crank without a puller.

Step-by-Step Procedure to Remove Mountain Bike Crank Without Puller
Removing the mountain bike crank without using a puller can seem daunting, but by following a few simple steps, you can take it off with ease. To start, you will need a few tools – a rubber mallet, a 6mm and 8mm Allen wrench, a screwdriver, and a cloth. The procedure may vary slightly depending on the type of crank and bottom bracket.
First, loosen the crank bolts using the Allen wrenches. Next, take the rubber mallet and gently tap the side of the crank arm to loosen it from the spindle. If the crank doesn’t come off, try tapping it from a different angle or using a little more force. Once the crank arm is off, you can clean it and the bottom bracket spindle. Be careful not to damage the bottom bracket.
The next step is to remove the chainrings from the crank arms. Using the Allen wrench and screwdriver, remove the bolts from the chainrings. Then take the chainring off and give them a thorough clean. Reattaching the crank arm involves reversing the process above. So, slide the crank arm back onto the spindle, apply a little grease, and tighten the bolts back into place. Finally, reattach the chainrings and tighten the bolts using the Allen wrench and screwdriver. Congratulations, you have successfully removed your mountain bike crank without a puller.
Alternative Methods to Remove Mountain Bike Crank Without Puller
If you don’t have a crank puller but need to remove your mountain bike crank, there are a few alternative methods you can try. The first method involves using a rubber mallet or hammer to gently tap the crank on the non-drive side. This may loosen the crank from the bike’s spindle, allowing you to pull it off by hand or with a makeshift tool like a wire hanger or pliers.
Another option is to use a long bolt or threaded rod that fits into the crank’s spindle hole. Insert the bolt into the hole and then use a combination of leverage and rotation to loosen the crank from the spindle. This method can require some trial and error to get right but can be effective if you don’t have a puller on hand. However, it’s important to be careful not to damage the bike’s spindle or threads with this method.
