View Full Version : Crank Arm removal help

03-03-2010, 03:02 PM
What is the easy way to remove the crank arm on the side with the front chain rings. I was able to pound with a hammer on the other side to get that crank arm off. Not sure of the best way to get the other side off. Not much room and donít want to damage any of the components. Thanks for your help in advance.


P.S. Temps are warming up in the Upper Peninsula of Michigan and am ready to get moving on my Maurader build.

I think a crank puller is worth the price. Mine was about $10 at the LBS.

Yup - there is no better way, and the tool will come in handy over and over.

Definitely. After pounding on the side with the cogs and breaking them...I got a crank puller and took it apart the first time, with no more fuss. Of course those cranks were no longer any good to me...right tool for the job.

I prefer this type of crank puller. You could use a breaker bar and a socket for stubborn cranks, and even add a length of pipe (commonly called a "persuader") to the breaker bar for really stuck crank arms.


My first one was one of these. It didn't hold up when I used a persuader on a tough crank arm.

In the book Brad just used a drift or metal rod stuck through the holes and a hammer. Worked fine for us. Ours came right off, the sprockets were never touched and you can pound just as hard through the drift as a straight shot. Cost? $0 Right in my price range.

Thanks for you help guys. I figured I would use a crank puller a few times so I just bought the universal one from Ebikestop.
