just pull the barrel n have a looksee , but not hard to change , no need to be in same spot too as no keyway on these cranks bottom end , just put on a hard surface (vice old rail track something hard , or just a hard steel block one side , hit the other side sharply and it should pop off . just be carefull with the pulley , practise on a couple of old duds 1st .
a taper fit so no need to locate anything , the nut will do the job and make sure its tight
