Crosspost from /o/ sqqtdtot,

I’m trying to disassemble this grease gun because the lockout rod fell inside the body of the gun. Most videos show the plunger (pic rel) having a nut or a cotter pin, this one has some kind of press fit pin. Can’t for the life of me get it to budge even with pressure released. No room for a hammer and I don’t want to tear up the rubber seal.

How do I get this little shit out? Many thanks bros

It appears to have some sort of press fit pin in it? Even when releasing the tension I can’t get this to budge
