Hi Router
It's roll pin,, it's one that tricky to get out because you can't drive it out, you will need to pull it out,, take a #39 or #40 drill bit and tap it in to the roll pin,, the drill flute must slide in the slot of the roll pin, drive it in about 1/2" or so then take a pair of vise grips and hook on to the drill then with a SMALL hammer tap on the vise grips, it will take a bit to get it to move out but once you have it out by 1/4" put the vise grips on the pin then tap on the vise grips again.
They can't be drilled out the norm they are spring steel and as hard as the drill bit..the norm. drill bit will just break off because of the slot in the roll pin,, it takes a bit to get this type out...but once you do drill the hole all the way b/4 you put a NEW roll pin back in... for a 5 cents part it's a pain.
NOTE ROUTER
It may not need to be removed, you may just need to rework the springs..
