On my 7' 451 I just take out the bushing bolt and pull the blade out the other end. Sometimes I use a large punch and hammer on the bushing to help it along if it sticks.
@@willietownsend3547 yes if you freeze the replacement is gets slightly smaller and if you heat the other part even better but you have to go quickly . use a socket and a long bolt to pul the slightly smaller socket and old bushing out. PB blaster helps also
