Marlin 81 Cartridge Guide Spring

How hard is it to replace the Marlin 81 Cartridge Guide Spring?

My Bolt-Action 22LR plinkster has this spring broken, so everytime I feed I need to push down the tip of the ammo to help it chamber.

I saw the part on e-gun parts (numrich ??).

Do I need to remove the barrel, or will it slide out of its position, and I just slide the new one in?

found this:
Yes, you will have to remove the barrel to replace the guide spring. The barrel is retained by a cross-pin through the receiver. This is a tapered pin and should be drifted out from the left side of the receiver to the right. If the barrel is tight in the receiver after the cross pin is removed, set the barrel in a padded vise and drift the receiver off to the rear using a nylon, or brass drift punch....
