I'M BUYING A FRAME FOR MY 20" LOWRIDER BIKE BUT I HAVE NO IDEA HOW TO DO ALL THE CRANK WORK LIKE:

I DONT KNW HOW 2 TAKE DA CRANK OUT OR TAKE DA SPROCKET OFF

CAN YOU GUYS HELP ***  

first you take the left pedal off. then you take the chain off and get some vise grips or channel lock pliers and turn it right not left.once you get that off their should be a flat piece wit two slits take a flat head screwdriver and a hammer and put the flat head in the slot and hammer to the right take that off and work the crank out without damaging the bearings  

It's been a while now...have you figured it out yet??
