Step 1. Remove the dust cover

The handwheel is tightened to the main shaft with a crank bolt. Mostly old fashioned cranks seal this bolt with a dust cap.Read more: How to find a replacement tenant Before you get to the crank-accessible part of the crankshaft, you’ll need to remove the dust cover. In my case, there was a small slit on the side of the dust cap’s lid that was pressed into place. You can insert a flat-head screwdriver and pry it out. All of these versions are screwed into place, the original dust cover being both rare and expensive. That’s because fragile plastics are easily damaged and they tend to get misplaced. So be careful when trying to make them loose.

Step 2. Remove the handwheel bolt

The handwheel is held in place by the handwheel bolt. I have a Park Tool crank bolt wrench, which has a 14mm socket on one side and an 8mm hex tool on the other.In this case I will need the socket wrench part.

Step 3. Remove the chain

Therefore, it is best to remove the chain and place it on the rack housing before removing the crank.Read more: how to reply to a text from a man saying this Make sure this tip is rotated far enough out or left out altogether. Or you’ll be like me and think the crank puller won’t move any further because the threads are dirty instead of the press sitting on the crank bolt.Be careful not to criss-cross the small threads in the crank. Especially in the absence of a dust cover, the threads can become dirty, making it difficult to snap the crank puller into place. The threaded part of the handwheel puller is screwed onto the handwheel. Once in position, the rotary head presses against the bottom frame’s main shaft, pushing itself and the crank with it, away from the main shaft.If the crank puller comes in about half an inch, you’re good to go. While holding the crank with one hand, the other hand can rotate the crank counterclockwise with the help of an adjustable wrench. I have never had too much trouble removing the crank with this tool. , no matter how old and broken they are. If the crank won’t budge, it’s just a matter of applying a little more force.
