Remove the dust cap from the crank (Picture B )

Loosen the crank bolt using the socket end of the tool or a suitable socket/ box spanner. Completely remove the bolt together with the washer. (Picture C)

Screw the threaded end of the crank puller fully into the crank. (Picture D)

Screw in the internal pusher until  resistance is felt. Using a suitable spanner or adjustable wrench, torque up  the internal plunger until the crank comes off the tapered axle.

Before re-fitting the crank onto the axle both components should be thoroughly cleaned and greased.

Place the square hole in the crank arm onto the square end of the bottom bracket axle.

During the manufacturing process of your bicycle, the cranks are pressed on by machinery. When fitting or replacing your crank, please remember after inserting the axle to use a rubber mallet and tap the crank lightly onto the axle. Without doing this your crank will come lose and may even fall off.

If you hear creaking coming from your cranks, it could be many things - your cranks, bottom bracket, pedals, frame, or even something as remote as your quick release skewers. If you are unable to isolate the problem, bring your bike to a bike shop.
