Stuck sear bar plunger???......any tricks??

[Thor]

Soak it in pentrating oil like KROIL for a few days, of perhaps put it in the oven at around 300 degree F for an hour, sometimes that will loosen things up! This is a trick I use when I CAINT get the 3/64" +- (I know it is really metric) diameter retainer pin, small little stubborn sucker! Thor
