    Crank question...

    I have this ****ty old bike that I'm trying to strip but I can't figure out how to get the cranks off.

    The crank was not held on with a dust cap with an allen head, rather a regular nut.
    So, I removed the nut and now there is just a bolt head inside the dust cap hole.

    Obviously a regular crank puller wont work, so, how do I remove this crank?
    Thanks.

    take the nut off and then use the crank puller, it's the way cotterless was back in the day, maybe they're still made this way somewhere, it can't be that uncommon

    is this an older frame/bb? I don't know if this helps but I had the same problem (crank puller wouldn't thread on since that bolt sticks out past the dustcap threads) on a goodwill bike that I was stripping and building back up cheaply for a friend.

    my solution was not something i would suggest on a nicer bike but i basically stuck a flathead screwdriver under the crank arm and pryed it upward. i tapped the screwdriver lightly with a hammer and moved it all around the crankarm... this slightly loosened the crankarm and allowed me to rock it back and forth on the spindle until it popped off. worked well and i got both arms off in 2 minutes with no damage to anything.

    of course it does involve sticking a screwdriver between your bb and crank arm and hitting it with a hammer so hopefully someone has a better suggestion. if you choose to try this, just tap it lightly with the hammer, thats all mine needed.

    But a regular crank puller screws into the whole vacated by the allen-headed screw that is first removed.
    Mine has no such opening.
    I'll get pics.

    Here.
    It's blurry, but you can see the nut that sticks out.



    And yes, it is an older P.O.S.
    So, that hammer method doesn't seem all bad.

    yeah very similar to mine.... pry up with the screwdriver and tap with a hammer, you should notice the crank arms move just a little bit on the spindle. after they move, you can just rock them back and forth until they come off (taper is your friend)

    It's a nutted spindle. A standard crank puller should work.

    My son's bike had this. A Park crank puller took it off easy.

    Yes, my crank puller worked fine upon second effort.
    I'm an idiot.
    Sorry.
