Right. The plunger has a little "shelf" in it that rides on the pin. You need to take tension off the pin to be able to drive it out easily. Unless you have 3 or 4 hands, it's best to get someone to help you, or use a C-clamp. Get a punch the right size, because a nail will definitely booger up the end, and then the pin will be useless. Don't ask me how I know this. ;DAWFUL CLOSE said:Every thing comes out the ejection port side of a Marlin
TO remove the lever spring, have some one push in on the plunger while you tap out the pin.
Go to Ace Hardware and purchase the #1 spring on their spring display board. Cut it to the same length as the factory pin and you will be home free. Spring should cost less than a buck.
