Video of How to Use a Crank Puller Tool

1 part needed for this repair — view & shop below

This video will demonstrate how to use a crank arm puller tool to remove the crank arm from an indoor cycle.

Tools Required:

Remove the crank arm bolt before installing the crank arm puller.
Crank arm threads may have over-spray of the paint or powder coating on them. This doesn't impact assembly of a new bike, but can present problems when it is time to remove and replace a crank arm in the field. The paint or powder coating can block the tool from threading in fully. Clean the threads before using your crank puller to avoid damage to the tool or crank arm. Use a stiff wire brush. If needed, use a tap the size of the threads in the crank arm being removed for heavy buildup. Common tap sizes are 22mm x 1.0 and 25mm x 1.0

Procedure:

To begin you must remove the crank arm bolt.
Thread the puller into the crank arm as far as possible by hand. Use a wrench if needed to install the outer piece of the puller in several threads.
Hold the threads of the tool in one hand.
Turn the handle with your other hand to adjust the shaft inside the tool outward. This will allow the tool to seat into the crank arm as far as possible.
Using a 7/8 inch wrench turn the crank puller as far into the crank arm as possible. CAUTION: If you only finger tighten the tool you risk damaging the tool and the crank arm.
Turn the handle of the crank arm puller clockwise to press the arm off of the bottom bracket spindle.
After the arm comes off the spindle hold it in place to use the wrench and remove the tool from the crank arm. It can be difficult to remove the tool otherwise.
