    park tool site should get you going.

    It's been over 20 yrs since I've done anything with a BMX bike, and i was too young to know anything then (=

    Actually, I have the 3-piece . How do I remove the old crank, and what do I need to know to install a new one?

    check out the

    other BB guides there on the repair help section of the park site. http://www.parktool.com/repair_help/...ttom%20bracket

    With a 3 piece crank, you'll first need to remove the crankarms. I guess most bmx cranks use a pinch bolt to hold 'em on, or if like most road/mtn bikes a bolt hold's em on the BB spindle. You'll likely need the proper tool to pull the arms off, same with removing/installing the BB cups.
