Rest the chain ring on a vice (covered with card) with the vice open enough for the crank arm only to fit through and whack the spindle end with a rubber mallet, the chainring and the bearings should come off together
Whats the matter Kid, don't ya like clowns? Don't we make you laugh? Aint we fukkin funny?
