does anyone know how to remove a chain ring from a one piece crankset? i cant for the life of me get the chain ring off. its an early 1960's schwinn crankset with the standard factory chain ring on it (4 circles). Is there a special way or tool that i need to pry this thing off or is it an actual part of the crankset? I want to put on a new ring if i can get the old one off. Secondly, what will i need in order to put the new one on? is it a cotter pin that they used? any help on this would be much appreciated thanks!
I assume you have the crank and bearings out of the bike. If you have a vice, place the right crank arm in the vice. Then use a big adjustable wrench or pipe wrench to loosen the bearing cone/nut holding the chainring on. The threads are normal, so turn the wrench counterclock wise.

Just reverse the process when assembling back together. You may need a large washer between sprocket and bearing cone/nut. Use whatever grease your have on hand for the bearings.

Here is Park Tools guide to one-piece cranks.
