Hey man thanks for the reply. Sorry if my post is kinda confusing english isn't my main language and I'm having a hard time figuring out the name of the bike pieces.

Lock ring was on, I already took it off. Basically I want to switch the wheel around because the nets (not sure if that's the good translation) to hold the gear are stripped and it was causing my chain to fall. The other side is brand new. The gear is just locked in really tightly and I'm scared to break something if I push too much.
